El Niño is an interannual catastrophic event caused by massive amounts of warm water flowing in from the mid-Pacific instead of the more normal northerly warm current. These events have a 6-8 year cycle, Published in Origins v 10, n. 1.
The cause of the 1908 Tunguska explosion in Russia remains somewhat mysterious. The most probable explanation is that a small comet exploded in the air and produced a blast wave that uprooted thousands of trees and killed many reindeer. Published in Origins v. 9, n. 2.
A review of the book, Ecological Biogeography of Australia. An exhaustive review of the geology, flora nad fauna of Australia. Published in Origins v. 8, n. 2.
Dates based on amino-acid racemization and uranium radioactive decay were quite different, with preference given to the radiometric dates. Published in Origins v. 8, n. 1.
A review of the book, Principles of Isotope Geology. This is an authoritative textbook on radioisotope dating that provides useful background information, regardless of philosophical persuasion. Published in Origins v. 6, n. 1.
The effects of glaciers are well-dccumented in modern and Pleistocene sediments. Some Precambrian and Paleozoic sediments show some features similar to those of modern glaciation, but there is some controversy over whether the features are the result of glaciers, submarine landslides, lahars, turbidity currents, etc. Published in Origins v. 6, n. 1.
Experimental evidence shows that wood can petrify in a few years or less when immersed in mineral-rich water. Published in Origins v. 5, n. 2.
The presence of various kinds of megabreccias in the geologic column, showing in some cases the transport of extremely large clasts, indicates energy levels on a scale that staggers our imagination. Published in Origins v. 5, n. 1.
Radiometric dates are subject to uncertainties due to the assumptions inherent in the method and to the effects of non-natural changes in the earth's crust on the third day of creation and during the biblical Flood. Published in Origins v. 4, n. 2.
Tektites are formed from molten target rocks by an extraterrestrial impact. Australian tektites dated at about 700,000 years are found resting on soil dating less than 10,000 years old. This discrepancy is unresolved at present, and provides an opportunity for further research that could be very significant for the question of radiometric dating. Published in Origins v. 4, n. 2.
A new journal, Catastrophist Geology, has begun publication. Published in Origins v. 4, n. 2.
Clastic dikes form when unconsolidated sediments are forced upward into overlying sediments by the weight of the accumulating sediments. Some clastic dikes intrude into layers supposedly many millions of years younger, indicating that the underlying sediments remained unconsolidated for unexpectedly long periods of alleged time. Such features challenge the conventional geologic time scale. Published in Origins v. 4, n. 1.
A review of two articles: On the Survival of Paleoforms, and The Tempo of Geomorphic Change. The scientific data of both papers indicate that much greater caution is warranted in approaching questions regarding the length of time involved in the past history of the earth. Published in Origins v. 3, n. 2.
A review of the book, The Nature of the Stratigraphical Record. The geologic record can be described as long periods of relative calm punctuated by brief catastrophic events. Numerous geologic features can be traced over large portions of the earth's surface. Published in Origins v. 2, n. 2.
This new concept indicates that some events in the past history of the earth may have proceeded much more rapidly than was previously believed. Published in Origins v. 2, n. 2.
