... replied that the cross sections were O.K . and their conclusion stands! Too much water and carbon. Strong, indirect evidence for the steady influx of icy comets comes from the geologists. They find that on and near the surface of the earth there is much more water and carbon than can be ascribed to the weathering of the earth's rocks. For example, the amount of carbon tied up in rocks (carbonates, etc.) is 600 times that now found in the combined atmosphere, hydrosphere, and biosphere. Where did all this extra carbon come from? The same question can be asked about the earth's water inventory. Geologists have long assumed that this excess water and carbon came from the outgassing of volcanos. But recent quantitative estimates tell us that the volcanic sources are grossly inadequate. So are all other possible terrestrial sources. Therefore, some scientists, such as D. Deming, University of Oklahoma, have been looking spaceward. Deming ventures that extraterrestrial sources of water and carbon may be four or five orders of magnitude greater than suspected. Obviously, a steady bombardment of icy comets might fulfill Deming's requirements. Down the long eons of geological time, they could have filled the oceans and showered all that excess carbon onto the planet's surface. Deming ups the stakes in the icy-comet controversy when he links these fluffy snowballs to the well-known vagaries of life on earth. "The extraterrestrial influx rate may also act as the pacemaker of terrestrial evolution, at times leading to mass extinctions through climatic shifts induced by ...

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.

Both groups have discerned huge slabs of crust that were once on the planet's surface but were subsequently thrust (" subducted") down under the continents.

Multiton basalt columns, formed by volcanic activity, were stacked horizontally, log-cabin style, to form outer walls. The inside was then filled with coral rubble to form a dry surface several feet above high-tide level. Radiocarbon testing finds signs of human habitation at Nan Madol as early as A.D . 500, and the megalithic construction was completed by about 1500."

Moreover if the particles found in these ice core samples are indicative of the particle size distribution which prevailed in the interplanetary medium at that time, then it may be concluded that the space number density of submicron sized particles must have uncreased by a factor of 105 or more. During these times the light transmission properties of the solar system would have been significantly altered resulting in major adverse effects to the earth's climate. Thus it is quite possible that these dust congestion episodes were responsible for the abrupt climatic variations which occurred toward the end of the last Ice Age."

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.

Jupiter's moon, Io, exhibits an anomaly that seems to call for a radical explanation. Io's volcanos erupt with such violence that molten material is flung to heights of 250 kilometers. These outbursts proceed from caldera, and one is led to assume that normal volcanic action is to blame. Unfortunately for this simplistic idea, Io does not seem to possess low-molecular-weight substances, such as water, that could serve as a good propellant at reasonable temperatures. Sulphur is common, but its atomic weight is so high that temperatures exceeding 6000 K would be required to shoot matter out to 250 kilometers. Gold suggests that Io's volcanos get their firepower from electrical sources. He points out that Io short-circuits Jupiter's ring current periodically. Gold estimates that 5 million amperes flow through Io when it passes through the ring current. The energetic eruptions and caldera might therefore be electric-arc phenomena. The electrical energies available are sufficient to account for the observed outbursts. (Gold, Thomas; "Electrical Origin of the Outbursts on Io," Science, 206:1071, 1979.) Comment.

Of the 75 craters mapped so far by Magellan , only one shows any signs of aging; i.e ., tectonic movements, lava-filling, etc. The surface of Venus should be hundreds of millions of years old, yet it looks freshly minted. The anticipated spectrum of degradation has not yet been seen. One theory is that recent lava flooding erased the old craters, and we now see only recent impact scars. 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? One idea not advanced by Kerr in Science is that Venus might be a recently acquired member of the solar system! From Science Frontiers #73, JAN-FEB 1991 . 1991-2000 William R. Corliss ...

A few years ago the answer to this question would have been a resounding "no" from the experts on both volcanism and impact cratering, the only geological processes known to eject solid material at substantial velocities. 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. Something was wrong somewhere. It has turned out that shock-wave theory had been misapplied. It is not the pressure that is important in ejecting bits of debris from around the impact site, but rather it is the pressure gradient. Anomaly extirpated!

Eleven such events are tabulated from October 12, 1980, to June 12, 1986. Perhaps the most dramatic event occurred on March 12, 1982, over Novaya Zemlya. The picture shows a sharply etched tongue of cold vapor arcing some 175 kilometers at a maximum altitude of 9.5 -10 kilometers. As with most of the plumes, movement of the vapor does not correspond to wind direction. Volcanic activity and natural methane gas releases are considered unlikely explanations. Since the islands involved are used for Soviet weapons tests, the plumes may be due to some incredibly energetic devices, although no radioactive releases or seismic activity seem correlated with the plume appearances. Queries to Soviet scientists have gone unanswered. (Anonymous; "Large Plume Events in the Soviet Arctic," Eos, 67:1372, 1986.) From Science Frontiers #50, MAR-APR 1987 . 1987-2000 William R.

... of acid rain brought on by the impact of an asteroid. We always look for external forces, whereas the real cause of "crises" in the history of life may be intrinsic to life itself. With a tip of the hat to the Gaia hypothesis, let us think of life-as-a -whole as a most complex, interlinked system. What might be the dynamics of such a megasystem? From the mathematical point of view, many of the processes involved, as life copes with the environment, are doubtless nonlinear, which means that chaotic conditions may sometimes prevail. In fact, the graphs presented below could have been taken right out of a book on chaotic systems. Life's extinctions and explosions might have no connection to asteroids, Ice Ages, or global volcanism. If something as simple as a spherical pendulum can lapse into chaotic motion, life-as-a -whole should show occasional wild behavior, too. Take our planet's weather as another example. Idealists once thought that given enough observations and computer power, weather could be predicted. But, alas, our atmosphere has also turned out to be a chaotic system, and long-term predictions are next to impossible. So, too, with life and its development. Those extinction-explosion plots may be just the paleontological expressions of a chaotic system. From Science Frontiers #59, SEP-OCT 1988 . 1988-2000 William R. Corliss ...

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.

For some 2,000 kilometers along the Martian equator west of Arsia Mons and Pavonis Mons stretches an area that is invisible to terrestrial radar. Of course, we can see this region; but, when a 3centimeter radar is pointed at it, no detectable echoes are returned. Thus, the term "stealth," as in the F-117 Stealth aircraft, Are the clever Martians trying to conceal something from prying earthlings, using, say, a "cloaking" device a la Star Trek? Of course not. Loose, unconsolidated sediments are poor reflectors of radar waves. Examination of Viking-Orbiter photos tell geologists that the "stealth" region is almost certainly thickly strewn with volcanic ash, which would absorb the radar waves very well.

We assume that natural forces are too erratic to sculpt such neat geometrical solids. This stance is sometimes justified, as confirmed by the hundreds of precisely executed stone spheres found in the jungles of Costa Rica. Nature herself, however, is often an expert craftswoman. Some concretions are beautifically spherical, so are some spheres fashioned in volcanic calderas. In Utah, though, southeast of Cleveland, in a formation called the Molen Reef, there are literally millions of stone spheres of more mysterious origin. E. Hansen described these in a recent issue of the Ancient American. "The spheres range in size from as small as a baseball to over 10 feet in diameter. The bigger ones are more perfectly round than smaller examples. After a lifetime of trying to form a theory of how these were formed, I can only throw up my hands in surrender! They are clearly formed as mud on a lake bottom, because when two touch, one will indent the other, or both will be equally distorted. The mud simply hardened over time into sandstone."

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.

The truth is that accumulations of elephant bones have indeed been discovered, but no one seems to have followed expiring elephants to these boneyards. We hope someone will tell us otherwise, but the tale seems apocrythal. The piles of elephant bones could, in fact, be the work of mazukus. (Mazuku means "evil wind" in Swahili.) It seems that there are places on this earth where CO2 and other deadly gases emitted from volcanic vents accumulate. J. Lockwood and M. Tuttle investigated three mazukus known to natives in East Africa. In these low-lying areas, they came upon the remains of small mammals and birds that has been asphyxiated by concentrations of CO2 dense enough to snuff out burning kerosene-soaked rags. Unfortunately for the elephantgraveyard legend, they found no elephant bones. (Anonymous; "Elephant Graveyards," Discover, 12:10, May 1991.) Comment.

... 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 ...
