The earth from afar must have seemed to be a disturbed top---on a geological time scale, of course! What could have perturbed the earth? One suggestion blames a sudden shifting of the planet's mass distribution, some sort of subterranean indigestion, like a subducted ocean plate suddenly plunging through into the lower mantle. (Kerr, Richard A.; "Did the Dinosaurs Live on a Topsy-Turvy Earth?" Science, 287:406, 2000.) The biological consequences of such a sudden tilting could have been severe. The event -- known as rapid true polar wander -- may have been accompanied by worldwide volcanic upheavals and reorganization of tectonic plates that would have played havoc with anything living in the Late Cretaceous period, 65 million to 99 million years ago. Although the notion that an asteroid was the immediate cause of dinosaur extinction about 65 million years ago has won wide acceptance, many paleontologists have argued that volcanic activity may have played a role in changing the climate and sending populations of the giant creatures into decline.

This was the time of the well-publicized, but still hypothetical, asteroid impact. It is said to have wreaked havoc on our wounded planet and, especially, the dinosaurs. Volcanos spewed out vast lava fields and filled the air with greenhouse gases and dust. It was a bad time for many life forms. Actually, It may have been far worse than generally advertised. In addition to the volcanic activity and climate change, the shock of the asteroid impact could have been sufficient to destabilize the immense amounts of methane hydrate that have long been locked up, frozen and dormant, in oceanic sediments all over the world. According to this scenario, once the shock of the asteroid impact released the methane from its icy prison, it rose to the surface of the oceans in a world-wide burp. Methane, unfortunately for the dinosaurs and many other life forms, is highly flammable. Lightning could have ignited it almost immediately if it was concentrated enough. A colossal firestorm might have then enveloped the entire planet. The whole atmosphere could have been afire. This, according to B.

Mauna Kea (4201 meters), Mauna Loa (4201 meters), and other Hawaiian peaks penetrate high above trade inversion. Together they create a visible wind wake some 3,000 kilometers long to the west -- many time-greater than any other island wind wakes to be seen on the planet. The effects of these soaring peaks are more than visual. Their wind wake drives an eastward ocean current that, in turn, draws warm water away from the Asian coast 8,000 kilometers distant from Hawaii.

They have calculated that the oceans are leaking water into the Earth's mantle five times as fast as it is being replenished. It is true that ocean water is being drained away at subduction zones where oceanic crustal plates dive under the continental plates; there's a 10,000-mile unsealed crack there. S. Maruyama and colleagues at the Tokyo Institute of Technology estimate that 1.12 billion metric tons of water leak through that crack in the earth's integument every year. Geologists have always assumed that most of this leakage was returned to the oceans through deep-sea vents and volcanic action, but Maruyama calculates that only 0.23 billion metric tons are recovered.

Within this visible cross section of the icesheet, layers of dark volcanic tephra serve as stratigraphic markers and datable age horizons. Systematic sampling of these layers at a well-known meteorite collection site (the Allan Hills Main Icefield) has revealed a band consisting of unusually dark and rounded particles, many of which are spheroidal. This debris layer (BIT-58) extends parallel to the stratigraphy of the ice established from the tephra bands, and thus apparently marks a single depositional event. Several kilograms of ice from two sites along this band were subsequently collected and melted, yielding a few grams of sediment for further study." Microscopic examination and microprobe analysis led to the following conclusions: "Although direct evidence of an extraterrestrial origin for this debris layer (such as the presence of cosmogenic 10 Be and 26Al) has not yet been obtained, the available data strongly suggest that this sediment originated as meteoritic spallation debris. This debris is distinct from other Antarctic 'cosmic dust' collections by virtue of its uniform, recognizable, ordinary chondrite composition and the consistent relation shown between grain size and texture. The BIT-58 layer probably originated from a single transient event, the passage and/or impact of a single large meteorite over the East Antarctic icesheet." (Harvey, ...

"Eight circular geologic structures ranging from about 3 to 17 km in diameter, showing evidence of outwarddirected deformation and intensive brecciation, lie within a linear swath stretching about 700 km across the United States from southern Illinois through Missouri to eastern Kansas. Based on their similar geological characteristics and the presence of diagnostic and/or probable evidence of shock, these structures, once classified as 'crypto volcanic' or 'cryptoexplosion' structures, are more confidently ascribed to hypervelocity impact.

Observation, however, has once again confounded expectation." In the snowy wastes of Antarctica, scientists have picked up meteorites that almost certainly came from the moon and Mars. And near St. Gallen, Switzerland, there was discovered a 22-centimeter block of Malm limestone that was apparently ejected from the Ries impact crater, almost 200 kilometers away, about 15 million years ago. We know all of these rocks are impact debris because they contain shatter cones indicating a violent origin. Not only did these bits of debris confound expectations, but their shatter cones implied shock-wave pressures far too low to achieve lunar and Martian escape velocities, or even the velocity necessary to propel that chunk of Malm limestone 200 kilometers.

Some of the key questions regarding the origins of life at submarine hydrothermal vent environments are focussed on the effects of temperature on synthesis and stability of organic compounds and the characteristics of the earliest organisms on earth. There is strong molecular and physiological evidence from present-day mircoorganisms that the earliest organisms on earth were capable of growing at high temperatures (about 90 C) and under conditions found in volcanic environments.

This is Periodic Spring, whose intermittent flow is a rare geologic phenomenon. The water is cold and clear, an indication that this is not a geyser like Old Faithful; such geysers, of volcanic origin, send forth hot water. Through the years various observers have timed the flows at anywhere from four to twentyfive minutes, with similarly varying dry spells. The intermittent flow is especially regular in late summer and autumn. During stormy periods or when there is heavy snow melt-off, the flow fluctuates but does not stop entirely."

After all, what force generated by small changes in the sun's output could stir up the earth's magma from a distance of 93 million miles? Stothers was surprised. "Stothers analyzed two immense catalogs, published in the early 1980s, that list more than 55,000 known eruptions since the year 1500. Concentrating on several hundred of the moderate-to-large eruptions, he found statistically significant patterns in eruption frequency that match the solar cycle. Eruptions seemed most numerous during the weakest portions of the solar cycle." Further, there was a 97% confidence that the correlation was not a statistical accident. The only cause-and-effect explanation offered by Stothers was negative and indirect. During periods of abundant sunspots, increased solar emissions jar the earth's atmosphere slightly.

But why would a planet's volcanism turn off so completely and so abruptly? Our earth, Venus' sister planet in many ways, still perks away, leaving craters of various ages. Why is Venus so different?

R.E . Gentet sets the geological stage in the following paragraph. "The 1849 gold rush to the state of California was the beginning of some of the most unusual reported finds of early man in North America. The gold-bearing gravels of California are recognized as being Tertiary in age, ranging from oldest to youngest Tertiary, depending upon the exact geological setting. At the time these gravels were deposited, volcanic eruptions also laid down lava beds, often tens or scores of feet thick. This occurred a number of times, and together with much erosion since then, have now resulted in table mountains, that is, lava-capped hills where the harder lava has better withstood erosion stresses while surrounding softer material has been swept away. It is under the hard lava beds, in the gold-bearing (auriferous) gravels, where the reported human bones and artifacts were found, not just once or twice, but hundreds of times by miners during the span of time from the 1850s through the 1890s while engaging in mining operations. Findings were spread over a wide geographical area." During the late 1800s, several books and many papers recorded the discoveries. Some of the finds were made by respected scientists of the day.

It was declared, rather imperiously, that a large asteroid had impacted the earth, causing much physical and biological devastation. Many scientific papers are still being written on this singular period in the earth's history, and the situation is no longer so clear-cut.

Some scientists, however, propose that the iridium layer was instead deposited through widespread volcanic activity. The proponents of an astronomical mechanism should be heartened by a recent paper in Nature, by W.S . Wolbach et al. Here is their Abstract: "Cretaceous-Tertiary (K -T ) boundary clays from five sites in Europe and New Zealand are 102 -104 -fold enriched in elemental C (mainly soot), which is isotopically uniform and apparently comes from a single global fire. The soot layer coincides with the Ir layer, suggesting that the fire was triggered by meteorite impact and began before the ejecta had settled." The composition of the hydrocarbons in the sediments points to the earth's biomass (mainly surface vegetation) as the source of the soot. The total quantity of K-T soot is equivalent to that which would be produced by burning 10% of all present terrestrial plant material.

While volcanic eruptions form most sea-mounts, these mountains consist of a nonvolcanic rock called serpentinite, and oceanographers are not entirely sure how the serpentinite mountains formed." The theory of plate tectonics has the Pacific plate diving under the Philippine plate along the Mariana trench. It may be that water trapped in the downgoing crust leaks out, rises, and serpentinizes the crust above. This altered rock, being lighter than that surrounding it, may slowly rise through it, eventually forming undersea mountains.

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."

Wake Island hydrophones, to the southeast, detected some submarine volcanic activity far south of the cloud, but no detonations in the area the cloud was spotted.

The transitional field is low in intensity and is typically non-axisymmetric. Geomagnetic impulses corresponding to astonishingly high rates of change of the field sometimes occur, suggesting that liquid velocity within the Earth's core increases during geomagnetic reversals." The time period required for the field to reverse was about 4500 years, as measured at Steens Mountain, Oregon. There were three periods of very rapid change (impulses), which hint at radical changes in the core. The average magnetic field at the earth's surface decreased to 20% of normal during the reversal. (Prevot, Michel, et al; "How the Geomagnetic Field Vector Reverses Polarity," Nature, 316:230, 1985.) Comment.

The others ran for their lives toward Njindom. By 10:30 AM authorities had found 37 bodies along a 200meter stretch of road by the lake. Blood was oozing from the noses and mouths; the bodies were rigid; first-degree chemical burns were present. Also, animals and plants along the shore had been killed. On August 17, the lake turned reddish brown, indicating that it had been stirred up somehow. Although Lake Monoun is in a volcanic crater, chemical analysis of the water found little of the sulphur and halogens normally associated with volcanic action. However, the analysis did find a tremendously high level of bicarbonate ions, which form from the dissociation of carbon dioxide. One theory is that an earthquake disturbed the carbonate-rich deep water of the lake, which as it rose to the surface and lower pressures, released huge volumes of carbon dioxide -- something like opening a soda bottle. The resulting wave of water and cloud of gas caused the deaths and devastation. If there had been some nitric acid in the cloud, the burns could be accounted for.

At the moment, every-one seems stumped by these strange creations of Nature. (Anonymous; "Who Made the Andes Islands of Ice?" New Scientist, 96:272, 1982.) Comment.

The rocky debris surrounding the spacecraft shows, to nearly everyone's surprise, strong evidence of sedimentary, layered structure. The rock formations display ripple marks, thin layering, differential erosion, and even hints of cross-bedding. The vision of ancient seas on Venus leaps to the mind, but according to the Russian scientists, it is far more likely that the sediments were created by winds, episodic volcanism, or repeated meteor strikes.

... people have been trying to prove that it is caused by the influence of the planets, particularly Jupiter with its 11.86-year period. A century of various correlations has convinced almost no one. John P. Bagby has now introduced a new piece to the puzzle of solar-system cyclic behavior. While searching for possible perturbations of the planets due to a tenth major planet or a dark massive solar companion (MSC), he discovered that the perihelia of the outer planets (orbital points closest to the sun) were being disturbed with an average period of 11.2 years. This is almost exactly the sunspot period. This serendipitous finding caused Bagby to wonder whether some common influence was causing not only the sunspot cycle and those perturbations in outer-planet perihelia but also cyclic volcanic and seismic activity on earth. Some correlations indeed do indicate a sun-earth link of some sort. Bagby suggests two possibilities: (1 ) Mutual resonance effects between the planets, (2 ) The effects of a massive solar companion. (Bagby, John P.; "New Support for the Planetary Theory of Sunspots," privately circulated paper, 1983.) Comment. Even "farther out" is the thought that gravitational waves or some unrecognized influence from the galaxy or beyond causes the whole solar system to "ring."

... The surges may be years apart; and they may occur periodically. The surges start high up on the glacier and propagate down to the foot, which plods along a few inches per day until the surge arrives. Then, it leaps forward, only to return to normality until the next periodic surge. The surges seem to occur when water spreads out under the ice, lubricating its flow. Beyond this we know little. Why do some glaciers surge while those right alongside behave normally? Are the surges really cyclic? The Variegated Glacier, in Alaska, for example, surged in 1906, probably in 1926, in 1947, in 1964-65, and in 1982 -- about 20 years between surges. The surges do not seem to be connected to earthquakes, climatic changes, volcanic heat, or anything obvious. (Beard, Jonathan; "Glaciers on the Run," Science 85, 6:84, February 1985.)

... Evidence For A Giant Pleistocene Sea Wave On the Hawaiian island of Lanai, limestone-bearing gravel blankets the coastal slopes. Called the Hulopoe Gravel, it now reaches a height of 326 meters above sea level. Taking into account the 1000,000-year age of the gravel and the slow subsidence of the Hawaiian Islands, the deposit probably reached 380 meters when it was first formed. The big question is how it got deposited at such great heights. Highsea stands are rejected by the authors in favor of a single episode of catastrophic waves about 100,000 years ago. Earthquake-generated tidal waves are considered unlikely because of the great heights involved. (The highest tsunami ever recorded in historical times reach ed only 17 meters above sea level.) A great meteor impact or submarine volcanic explosion are good possibilities, but the authors favor a giant submarine landslide on the Hawaiian Ridge, noting that in 1958 a similar event off Alaska produced a wave that reached 524 meters above sea level.

... than that which meets the eye when standing on its rim. The immensity of the total excavation job can be appreciated by a trip to Red Butte near the southern rim. This conical hill rises 300 meters and is capped by the remnants of a lava flow, which has a radioisotope date of 9 million years. Thus, in the last 9 million years not only has the entire gorge of the Grand Canyon been cut but also a much greater volume of rock 300 meters thick adjacent to the present north and south rims. The immensity of the volume of sediment removed is not the real issue. The first problem emerges downstream from Red Butte at Pierce Ferry. There we find 200 meters of Hualapai limestone, which has been dated at 8.7 million years from a thin layer of volcanic ash within the limestone. When this limestone was laid down, the geology is emphatic that no large, sediment-carrying river was in the vicinity. Most geologists agree that the lower end of the Grand Canyon was not active around this time. No one knows where the Col-orado River was flowing at this period. Some say southwest from Peach Springs; others point to a northwest route into Utah. All the likely alternate routes face serious geological obstacles such as lava barriers. What does seem certain is that the stock explanation of the formation of the Grand Canyon is incorrect. It was not steadily ground out, cutting everdeeper as the whole region was slowly elevated. Actually, geologists believe that the region stopped rising over 50 million years ago. Where, then, did the ...

... ; viz., plankton and dinosaurs. The vaunted iridium anomaly in deep-sea cores is spread through a considerable thickness of sediment. Even after allowing for the mixing of sediments, the iridium-rich layer is thousands of years thick. According to the asteroid scenario, the clay layer separating the Cretaceous from the Tertiary should represent the fallout from impact-raised dust, which would include asteroidal material and a mixed sample of earth rocks. However, in Denmark, the boundary is marked by the so-called Fish Clay, which is almost pure smectite -- a single mineral and not a mixture of terrestrial rock flour. If it wasn't an asteroid impact, why the iridium concentration? At least three hypotheses have been proposed to circumvent the asteroid debacle: (1 ) volcanic activity; (2 ) a concentration of micrometeorites, thousands of tons of which fall each day, through extreme reduction of sedimentation; and (3 ) selective enrichment of iridium by an anoxic environment acting upon kerogenand pyrite-rich clay. In short, some geologists at least do not find the asteroid hypothesis compelling at the moment.

Science Frontiers ONLINE No. 36: Nov-Dec 1984 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Subterranean Electric Currents We have little appreciation of the immense electrical currents that flow through the rock formations beneath our feet. These "telluric" currents are primarily those induced by the earth's changing magnetic field, as it is affected by the solar wind. Telluric cur-rents do not flow uniformly through the earth's crust. Rather, they seek out low resistance rocks, in accordance with Ohm's Law. Such current concentrations can be detected at the surface with magnetometers. The present paper announces the discovery of a regional telluric current flowing in the vicinity of the San Francisco Peaks volcanic field in Arizona. The shallow part of the current flows in an unidentifiable "geoelectrical" structure not more than 10 kilometers below the surface. There are no surface hints as to what this geoelectrical structure could be. (Towle, James N.; "The Anomalous Geomagnetic Variation Field and Geoelectric Structure Associated with the Mesa Butte Fault System, Arizona," Geological Society of America, Bulletin, 95:221, 1984.) Comment. Similar anomalous magnetic fields exist in many areas, indicating a vast subterranean system of poorly understood geoelectrical structures. Some of the channeled earth currents are man-made, being the return paths in electrical power transmission systems. The return paths may be far-removed from the actual power lines because they tend to follow the geoelectrical structures. Reference. Other important subterreanean electrical currents are described in ...
