Similar but much smaller "microtektites" appear in deapsea de posits in the adjacent oceans. Radiometric and fission-track dating indicate that the tektites solidified about 700,000 years ago. Yet, their geological age, as measured by the age of the terrestrial sediments in which they are found, is only a few thousand years. This great disparity in age engendered a confrontation between geologists and geophysicists. The latter insisted on their 700,000-year figure; the former said "maybe so" but the tektites are still found only in very young, superficial sediments. The point here is that time-of-solidification may not be the same as time-of-fall. At stake is the prevailing theory, now dogmatically proclaimed, that tektites are created when a large asteroid impacts the earth, ejecting molten droplets of rock which shower back to earth as solidified tektites. No one has ever found a suitably large crater ( 200 miles in diameter) assignable to the Australasian tektite strewn field. Nevertheless, the impact model prevails; and the young geological age of the tektites is dismissed as erroneous. A Soviet scientist, E.P . Izokh, has recently proposed a radically different scenario that would produce both ...

They come in various shapes: droplets, buttons, even dumbbells. By general agreement, tekites are attributed to meteoric or cometary impacts that melt terrestrial rocks and splash liquid droplets into the atmosphere. There they are shaped by aerodynamic forces and solidify. This scenario is all very reasonable, but some nagging problems remain. Where-o -where is that crater? 770,000 years ago, a huge meteor hit somewhere on earth and strewed an immense batch of tektites and microtektites over fully 10% of our planet's surface (about 5 x 107 square kilometers). This is called the "Australasian strewn field." Such a recent cataclysm must have left a large and inescapable crater somewhere. The problem is that no one has yet found it. (Ref. 1) Many lines of evidence suggest that the missing crater is in Indochina. C.C . Schnetzler and J.F . McHone located four likely structures in Laos from Landsat images. However, visits to these areas found no evidence of an impact. (Ref. 2) So, this mystery persists. How were the Muong Nong tektites formed?

Science Frontiers ONLINE No. 53: Sep-Oct 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Tektite-like objects at lonar crater, india Arguments about the origin of tektites persist in the scientific literature. A strong consensus has these small, drop like glassy bodies originating when meteors smash into the earth, liquifying themselves and some of the surface rocks. The resulting liquid droplets solidify in flight and when they descend form "strewn fields" hundreds, even thousands, of miles in extent. The main argument has been over whether the actual impact craters giving rise to the tektites might actually be on the moon instead of the earth. Looking over the literature, one sees that this debate has been characterized by much invective and scientific infighting. Today, most scientists concur that some tektite strewn fields are definitely associated with specific, although distant, meteor craters on the earth's surface. Unfortunately, the large separations of craters and strewn fields add a circumstantial flavor to the evidence. However, some tektite-like objects are to be found in the immediate vicinities of terrestrial craters, but not in far-flung strewn fields; viz., the Aouelloul Crater in Mauritania, and the Zhamashin Crater in the USSR. Another example has now come to light: the Lonar Lake Crater, a 50,000-year-old impact crater, in the Deccan flood basalts in India.

Science Frontiers ONLINE No. 25: Jan-Feb 1983 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Review Of The Tektite Problem Tektites are small glassy stones with drop-like and button-like shapes. They are found primarily in four strew fields in Europe, Australia, North America, and Africa. Just about everyone believes that tektites are once-liquid droplets of rock that were solidified in flight. The major question -- often intemperately debated -- is the location of the tektite source. Are they of terrestrial, lunar, cometary, or some other origin? A recent study by Shaw and Wasserberg, using element abundances as a guide, strongly favors a terrestrial origin, with meteor impacts serving as the liquefying and splashing agents. Indeed, specific craters have long been associated with the European and African strew fields. Those who believe that the tektites were splashed all the way from the moon by meteor impacts have not given up yet. One provocative fact stressed in this article is that the ages of the four groups of tektites are 35, 14, 1.3 , and 0.7 million years. Tektites are all quite young! (Smith, Peter J.; "The Origin of Tektites -- Settled at Last?" Nature, 300: 217, 1982.) Comment. Were there no tektite-forming meteor impacts prior to 35 millions of years ago?

New finds of tektites have expanded the strewn field of these Australasian tektites to include part of China. It now appears that about 30% of the earth's area was subjected to this stony bombardment. It is inescapable that the Australasian-tektite fall was a major event in the earth's history. But where are other signs of this great catastrophe? The present consensus holds that the Australasian tektites originated when a large celestial body slammed into our planet somewhere in Southeast Asia. The energy of the impact splashed droplets of molten rock into the atmosphere, where they were shaped aerodynamically and then fell as tektites. The extent of the immense Australasian-tektite strewn field implies a hard-to-miss crater about 100 kilometers in diameter. Yet, despite the geological recency of the event and despite much geological surveying, no convincing crater has been discovered. (SF#115) So, we have abundant evidence of a terrestrial event encompassing much of the planet but no "smoking crater"! The mystery deepens when one realizes that whatever cataclysm sent the Australian tektites aloft may have been comparable in magnitude to the impact that extinguished the dinosaurs (and other fauna) some 65 million years ...

The age of formation for these tektites, as determined by both fissiontrack and potassium-argon dating lies between 700,000 and 860,000 years. Geological evidence, however, suggests that the tektites fell only 7,000 to 20,000 years ago -- a substantial discrepancy. Surely, say some, these old tektites were washed out of some equally old deposits and transported to the young strata where they now reside. Not so, say Australian geologists, because most of these tektites are found in areas devoid of outcroppings 700,000 years old. Furthermore, the rather fragile tektites show little signs of wear, as they should if transported by flood waters for long distances. These and other geological facts militate against the 700,000-year date. Geologists have questioned the two dating techniques, while geophysicists think the geological evidence is shaky. (Chalmers, R.O ., et al; "Australian Microtektites and the Stratigraphic Age of the Australites," Geological Society of America, Bulletin, 90:508, 1979.) Comment. It is important to resolve this issue because the dating methods employed are crucial to the now-dominant theory of plate tectonics. In particular, the 700,000-year figure seems to represent a major crisis in biological and geological history. Reference. We expand on the ...

The tiny, often-illustrated teardrop- and button-shaped tektites clearly seem to have been formed when an extraterrestrial object smashed into the earth, melted terrestrial rock and soil, and splashed the fluid droplets over thousands of kilometers of Australia and Southeast Asia. Solidifying in flight, these par-ticles fell by the millions. Aerodynamically sculpted Australasian tektite But another type of tektite is also found in Southeast Asia. These are the layered or Muong-Nong tektites, which are not aerodynamically sculptured. They come instead in large, irregular masses, 3-20 centimeters thick, weighing up to 24 kilograms. Their layered appearance is thought to result from flow and stirrings as they solidified in small pools of melted rock and soil splashed from nearby impact craters. These irregular chunks of solidified melt could not have traveled great distances like their streamlined brothers. They lie at most only a few crater diameters from their parent craters. Since layered tektites are found over an area 800 x 1140 kilometers in extent, and they are not far-travelers, Southeast Asia must have been peppered with many small cosmic projectiles 700,000 years ago (the disputed age of the event).

Since tektites are supposedly formed during meteor collisions with the earth, many scientists thought the evidence, circumstantial though it may be, very convincing.

And, believe it or not, the rains of tektites discussed below may have been the forerunners of climatic catastrophes similar to the postulated nuclear winters. We shall call them "meteor-impact winters. First, a tad of background: Great meteor impacts and tektite events seem to have occurred nearly simultaneously with deep-cutting biological extinctions and reversals of the earth's magnetic field. Ever since this apparent synchrony was recognized a few decades ago, theorists have been vying in generating scientific scenarios, especially some mechanism that would reverse the earth's magnetic field. New entrants in the lists are R. Muller and D. Morris, two Berkeley physicists. Here is how they see it: "A sufficiently large asteroid or cometary nucleus hitting the Earth lofts enough dust to set off something like a 'nuclear winter.' The cold persists long after the dust settles because of the increased reflectivity of the snow-covered continents. In the course of a few centuries, enough equatorial ocean water is transported to the polar ice caps to drop the sea level about 10 meters and thus reduce the moment of inertia of the solid outer reaches of the Earth (crust and mantle) by a part in a million.

First, at least within certain large classes of lunar craters, internal origin (i .e ., some form of volcanism) predominates over impact; this result raises questions about the reality of the 'era of violent bombardment.'Second, the origin of tektites by meteoric impact on the earth cannot be reconciled with physical principles and is to be abandoned. The only viable alternative is origin by lunar volcanism, which implies the following: continuance of (rare) explosive lunar volcanism to the present time; existence of silicic lunar volcanism and of small patches of silicic rock at the lunar surface; a body of rock in the lunar interior, probably at great depth, which is closely similar to the earth's mantle and which contains billions of tons of volatiles, probably including hydrogen; and the origin of the moon from the earth after the formation of the earth's core."

The sudden change in the abundance of forest plants suggests that the winters became much more severe while the summers remained about the same. At about the same time, the radiolaria were devastated by some sort of disaster. This was also the time when the North American tektite strewn field was deposited -- a field that stretches halfway around the world. John O'Keefe hypothesizes that some of the tektites and microtektites that rained down during this period missed the earth and went into orbit around it, forming an opaque Saturn-like ring. This ring might have lasted a million years or more; and its shadow could have caused the extrasevere winters postulated from botanical data.

Now one reads everywhere of huge terrestrial impact craters, iridium layers, and tektite deposits.

Those headlands less than 40 meters high have lost most of their dunes, leaving only raw, unweathered rock. On the other hand, the higher headlands have retained these dunes. Australians B. Young and T. Bryant hypothesize that a tsunamis 40 meters high swept the lower headlands clean about 100,000 years ago. They can even plot the incoming wave's direction, because a few remnants of the coastal dunes still cling to the southwest corners of the headlands along the NSW coast south of Newcastle. In their scenario, the tsunamis came from the northeast, smashed into the Solomons, southeastern Australia, and northeastern New Zealand.

The absence of a smoking gun (a sufficiently large terrestrial crater with an age of 65 million years) has allowed volcanists to deny the cosmic catastrophists a complete victory. However, the recent identification of tektite-like glasses at the Cretaceous-Tertiary boundary (KTB) on Haiti is leading geological detectives closer and closer to the missing crater. Elsewhere in the world, the KTB is characterized by an iridium anomaly and a thin layer of "impact clay" consisting of tiny bits of shocked minerals. At Beloc, on Haiti, though, geologists find a 55-centimeter-thick layer of glassy debris. Approximately 25% of this stra tum consists of 1-6 -millimeter particles of tektite-like glass. Most of the glass particles are spherical, but a few have the splash-forms and dumbbell shapes of bona fide tektites. The thickness of the Haitian deposit and the large sizes of the particles suggest that the smoking gun must be nearby. Ironically, the Haiti stratum was originally classified as of volcanic origin; and we must add that we are presenting here only the conclusions of the asteroid school.

Such flips can of-ten be correlated with climate changes, global ice volumes, sea-floor spreading rates, and deposition of black shales, tektite falls, biological extinctions, etc. The frustrating thing is the lack of clear-cut cause and effect; that is, how these phenomena are linked physically to the geomagnetic field. Part of the problem is that we can only guess at how the geomagnetic field is generated. Let us assume that the earth's magnetic field is created by dynamo action in the planet's fluid core. P. Olson finds analytically that the core dynamo may reverse sign due to fluctuations in core turbulence caused by two competing energy sources: heat loss at the mantle-core boundary and progressive growth of the inner core. In concept, the heat lost at the core-mantle boundary might be linked to climate changes and sea-floor spreading. Taking a different tack, D. Gubbins has investigated the possibility that field reversals are triggered by ice ages and meteorite impacts (tektite falls). The physical mechanism here would be the increase in pressure upon the core, which affects the rate of freezing in the outer core, and thus the power available to the core dynamo. Gubbins found that these externally caused pressure changes were too small to explain the polarity changes. However, the parameters involved ...

... Geologist G. Patterson, University of Memphis, thinks that the huge chunks of sandstone came from coastal Louisiana and were carried some 650 kilometers (400 miles) inland by the giant tsunami raised by the asteroid or comet that smashed into the Yucatan to close out the Cretaceous. That, of course, was when the dinosaurs were forced into oblivion. But could the tsunami really have transported such huge rocks 650 kilometers? (Falk, Dan; "Washed Up," New Scientist, p. 26, November 7, 1998.) Comments. Tsunami debris from the end-Cretaceous impact has been found along the Gulf Coast and on some Caribbean islands. In northeastern Mexico, geologists have found a debris layer 3-meters thick that is also of the right age. This layer contains tektites, glass spheres, plant material, and an iridium anomaly. (SF#85) However, these debris deposits can hardly compare to the far-inland Arkansas sandstone chunks. From Science Frontiers #121, JAN-FEB 1999 . 1999-2000 William R. Corliss ...

... fossil meteorites have been found. All meteorites, except, four, have been found in a 60 cm thick bed called the Archaeologist. This bed represents a few hundred thousand years and contains several hard ground surfaces...Many of the Archaeologist meteorites are prominently angular in shape whereas others are round. This seems difficult to reconcile with an atmospheric breakup of a single large meteorite." B. Schmitz and M. Tassinari, the authors of this paper, suggest that this rare concentration of fossil meteorites represents an unusual event in the solarsystem history, possibly a major collision in the asteroid belt. (Schmitz, Birger, and Tassinari, Mario; "Early Ordovician Meteorites: How Many Falls?" Eos, 79:F50, 1998.) Comment. It should be added that tektites and microtektites (impact debris) are likewise found mainly in recent, superficial deposits, even though many ancient impact craters are now recognized on earth.

Science Frontiers ONLINE No. 49: Jan-Feb 1987 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Geomagnetic Reversals From Impacts On The Earth R.A . Muller and D.E . Morris review the evidence tying geomagnetic reversals to the impacts of large bodies with the earth: the tektites and microtektites; the climate changes; the biological extinctions, etc. Then they propose a physical mechanism for geomagnetic reversals: "The impact of a large extraterrestrial object on the Earth can produce a geomagnetic reversal through the following mechanism: dust from the impact crater and soot from fires trigger a climate change and the beginning of a little ice age. The redistribution of water near the equator to ice at high latitudes alters the rotation rate of the crust and mantle of the Earth. If the sea-level change is sufficiently large ( 10 meters) and rapid (in a few hundred years), then the velocity shear in the liquid core disrupts the convective cells that drive the dynamo. The new convective cells that subsequently form distort and tangle the previous field, reducing the dipole component near to zero while increasing the energy in multipole components. Eventually a dipole is rebuilt by dynamo action, and the event is seen either as a geomagnetic reversal or as an excursion." (Muller, Richard A., and Morris, Donald E.; "Geomagnetic Reversals from Impacts on the Earth," Geophysical Research Letters, 13:1177, 1986.) Comment. That the earth's field is generated by internal dynamo action is ...

... Science Frontiers ONLINE No. 6: February 1979 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Earth, the magic top The Journal of Physics is a most respectable British scientific publication, but in a recent issue we find an article that would warm the heart of Ignatius Donnelly, to say nothing of Hapgood, Brown, Velikovsky, and more recent catastrophists. Employing a wide span of data from complex top theory to ancient legend, Warlow suggests that the earth has undergone many violent catastrophes, some of them within the time of man. Flood legends, geomagnetic reversals, tektites, paleoclimatology, salinity crises, and other familiar standbys of the catastrophists force P. Warlow to examine the stability of the earth in the presence of astronomical collisions and near-collisions. He shows that the earth rotates slowly and that, even with the stabilizing equatorial bulge, our planet is rather sensitive to outside forces. It is, he says, like a tippe top or magic top; a 8,000-mile-diameter top that turns over repeatedly in response to external influences. Did not the ancient Egyptians write that the sun once rose in the west? Are there not massive faunal extinctions? Have not stray solar-system bodies left scars on all the inner planets?

... the earth and its sensitive biological cargo. This supposed Mirror-Matter planet happens to be the conceptual double of a Normal-Matter, hypothetical planet named Nemesis, which was proposed in the 1980s to account for the same periodical extinctions in the fossil record. However, diligent searches did not locate Nemesis. Of course, if Nemesis were made of Mirror Matter, as now proposed, it would have escaped telescopic detection then and would still elude our telescopes today! (Schilling, Govert; "Through the Looking Glass," New Scientist, p. 16, April 28, 2001.) Comment. Not only is a crater missing at the Tunguska site, but no one has been able to positively identify the immense impact crater that we suppose must have been excavated when untold numbers of tektites rained down upon Australia, Southeast Asia, and the Indian Ocean about 800,000 years ago.

... , and mysterious devastating fire from space." Even some of the place names in New Zealand relate to some kind of catastrophe. In the province of Otago, there is Waipahi (place of the exploding fire) and Tapanui (big explosion). Oral history is entertaining, but scientists want something more palpable before they will entertain Velikovskian ideas about recent history. Well, if you visit Tapanui (big explosion place), you can find Landslip Crater, a 900 x 600meter depression 130 meters deep. This does not have the appearance of a bona fide meteor crater, but all around it are suspicious signs. For example, treefall distribution from 800 years ago was radially away from Tapanui out to 4080 kilometers. In the same area one finds the trinities, small globules of silicates with tektite overtones. And then there is the extirpation of the moas about this time. To be sure, there are separate, conventional explanations of all these phenomena. But, if you add the Maori oral traditions to all these suspicious physical signs, a Tunguska-like event does not seem impossible.
