... evidence of high speed flight through the atmosphere. Estimates for the formation of the australite field based on 14C dating range from 16,000 to as recently as 5000 years before the present. Some advances seem to be happening in the study of tektites - the small, glassy, meteoritic allies of catastrophism which are often found in the same geological horizons as evidence for geomagnetic reversals, faunal extinctions, volcanic maxima and sea-level changes. An excellent summary of the recent trends was presented by Peter J. Smith in "The origin of tektites - settled at last?" Nature vol. 300, 18 Nov. 1982. Smith, editor of Open Earth, writes in a clear ...
652. A Maya Record of Two Thousand Years? [Journals] [Catastrophism & Ancient History]
... (Hawkes), two calendars beginning with catastrophe- Indian (Parker) and Maya (Thompson), and the start of the Kish dynasty (Mellart). The geophysical evidence pointing to -1561 is sensational, and generally self-consistent. Daley (1926, 177) and Kuenen (1950,538) arrive at this approximate date for a geologically rapid drop in sea level of 16 to 20 feet, but it is not implied that this drop was rapid in terms of human time scale. If the water did not disappear in the formation of glacial ice caps it receded because of massive mountain building on land, or both. In any case, rapid changes of this kind ...
653. Radiation and the Paleontological Record - The Stroboscopic Model [Journals] [Catastrophist Geology]
... From: Catastrophist Geology Year 3 No. 1 (June 1978) Home | Issue Contents Radiation and the Paleontological Record - The Stroboscopic Model Peter E.Gretener Department of Geology University of Calgary Calgary, Alberta, Canada. Schindewolf (1963, 1977) and others see the reason for rapid evolutionary changes in increased cosmic radiation. Uffen (1963) postulated that such increases are to be expected when the Earth's magnetic field vanishes during magnetic reversals and the shielding effect of that field is nonexistent. It has been argued that at present radiation levels the shielding effect is not really essential since the atmosphere itself provides sufficient protection. I propose a slightly more sophisticated model which may reconcile ...
654. Society News [Journals] [SIS Workshop]
... of interest as an attempt to pursue to a conclusion the question which has driven many dissident historians, such as Heinsohn and Sweeney: what if Herodotus was right? '. In assessing the merits (or otherwise) of Lasken's proposal, maybe this question can finally be answered, one way or the other. Contributions welcome. Harold Tresman's Geological Genesis reappears in this issue because of a dreadful attack of the gremlins in Workshop 1992:2 - because of a computer mix-up, it appeared without any references and with its second part only in a preliminary form. The only thing to do was to reprint the corrected article in full; apologies to all. The third is Trevor ...
655. Velikovsky at Harvard [Journals] [Pensee]
... ignored my replies to critics. It became an emotional crisis for me. But despite years of neglect, I survived, as you see." The capacity audience in Lowell Lecture Hall, obviously sympathetic toward Velikovsky, listened attentively as, in a slow and deliberate manner, he described how he "pitted history against folklore, folklore against geology, geology and paleontology against astronomy. I found that my thesis can be sustained." Antiquated Textbooks That thesis came under severe attack in 1950; but today, he observed, it is not his book, but the textbooks that "are mostly outmoded. Those of 1950 are antiquated." An astronomer could write during the 1950's ...
656. Apophoreta [Journals] [Catastrophist Geology]
... From: Catastrophist Geology Year 1 No. 1 (June 1976) Home | Issue Contents After a banquet in ancient Greece, guests received some eatable or drinkable gifts, APOPHORETA- things to be carried off', to take home. On this page a column is started in which provocative hypotheses are presented. They may serve to stimulate thought and research - and the correspondence for the Comments' column of this journal. Apophoreta Early this year, professor Doeko Goosen in Enschede, Holland, told me that there was something odd about the iron content of the early-Holocene coversands of the Netherlands. These sands are thought to have been formed through a combined fluvial and aeolian activity ...
657. Radio-Carbon Dating [Books]
... VII | Chap 4: I | II | III | IV | Chap 5: I | II | III | IIII | PART IV : Appendixes I | II | III | IV | Acknowledgements | Notes And References | V Radio-Carbon Dating 1. The methods used for dating rocks can only be of interest to compute the length of `geological ages'. For periods less than a 100,000 years, new methods were to be looked for. Amongst them, the radio carbon method (Carbon fourteen or C14) occupies a predominant place. Our atmosphere is composed of various elements: mainly nitrogen (78.1 per cent), oxygen (20.95 per ...
658. Stories of Radioactivity and Mutations [Journals] [SIS Workshop]
... a large, extraterrestrial body which, in turn, could have induced radioactivity or allowed exposure to intense cosmic radiation, and thus give rise to DNA mutations. Not wishing to suggest the agent, I have used the general term radiation' in my previous article to describe the cause of mutations which accompanied each episode and which left no apparent geological trace. The term could cover the full range of electromagnetic radiation, beginning with heat, and could also include any type of short lived radioactive radiation. But the lack of geological trace does not mean that there is only supposition for proof of radiation. Velikovsky has adequately argued his ideas on evolution from the geological and palaeontological viewpoints [ ...
659. Galactic Domains, G Fluctuations and Geomagnetic Reversals [Journals] [Catastrophist Geology]
... From: Catastrophist Geology Year 2 No. 2 (Dec 1977) Home | Issue Contents Galactic Domains, G Fluctuations and Geomagnetic Reversals Harold Aspden Southampton England Summary The degree of constancy of the universal constant of gravitation G is discussed The hypothesis is presented that a constant G is subjected to occasional short-duration fluctuations at times of reversal of the geomagnetic field. Evidence suggests a correlation between field reversals and deformations of the Earth's crust, and the hypothesis is turther supported by the one to four frequency correlation between the galactic cycle and related sedimentation sequences. 1 - The Constancy of G The universal constancy of fundamental physical constants over a Cosmic time-scale is a oasic issue in theoretical physics. ...
660. Geomagnetic Reversals? [Journals] [SIS Review]
... the field as evidence of an exponential decay compatible only with a catastrophic origin within the last few thousand years (SISR II:2 , 1977, 42 - 46, with response by John Milsom, and II:4 1978, 110-111). Recently, geomagnetic reversals have been connected with such phenomena as faunal extinctions, ice ages, geological change, falls of tektites, vulcanism and even cultural discontinuities. (For interpretations of the simultaneity of some of these phenomena attributing the events to enhanced radiation, which might be considered in conjunction with a zero-state geomagnetic field, see papers by Schindewolf, Salop, Aspden and Kloosterman in Catastrophist Geology 2 No. 2 , 1977.) ...
