Questions on the Methodology of Geology
A review of the book, The Structure of Geology. Geology differs from sciences such as physics because it is largely "retrodictive", inductive, and historical. Published in Origins v. 6, n. 2.

A number of factors could affect the relation of C-14 concentration to real time. The author discusses the effects on C-14 dates of cosmic ray intensity, geomagnetic field strength, water vapor concentration, and dilution by the biosphere carbon. Published in Origins v. 6, 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 Coconino Sandstone has traditionally been interpreted as wind-deposited, but fossil trackways in this formation point to underwater deposition. Published in Origins v. 5, n. 2.
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 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.
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.
Claimed correlation of C-14 ages with depth is not a sound argument for the accuracy of C-14 dates because in the great majority of cases, a linear relationship between depth and C-14 concentration does not exist. Published in Origins v. 2, n. 1.
A review of the article, Non-Poisson Distributions Observed During Counting of Certain Carbon-14-Labelled Organic (Sub)Mono-Layers.Small anomalies in counting C-14 disintegrations are probably explained by the experimental conditions and do not offer help for reducing the chronology based on C-14.
