Science Frontiers ONLINE No. 41: Sep-Oct 1985 Issue Contents Other pages Home Page Science Frontiers Online All Issues This Issue Sourcebook Project Sourcebook Subjects Did the australites fall recently?Many thousands of australites, tektites strewn over Australia and Tasmania, have been found over the years; but, except for five, all were discovered loose on the surface or in unconsolidated sediments. Even the five australites found in rocks were in grit, sandstone, and other rocks that were hard to date and could have been recently lithified. Although the "official" date for the australite fall is 700,000 BP, the authors of this article, and presumably other Australian geologists, find "it difficult to believe that australites fell as long as 700,000 years ago." (Cleverly, W.H ., and Kirsch, Steve; Meteoritics, 19:91, 1984.) Comment. A few geologists even venture that this catastrophic event may have occurred just a few thousand years ago, and may be reflected in myth and legend. Reference.

... a moon, or Jupiter, or some similar body, explosively ejected the glassy tektites, embedded in an icy cometary body some 700,000 years ago, the tektites could, after cruising through space for millenia, have fallen to earth recently and over a wide area. Thus, both geologists and geophysicists would be satisfied! (Sullivan, Walter; "New Answer Proposed for Tektites: A Comet," New York Times, November 28, 1989. Cr. R. Adams) Comment. Russian scientists have long suggested that comets may be ejected from solar-system bodies and have been laughed at by American scientists for their trouble! Reference.

... , 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.
