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 the book, Scientific Creationism (Public School Edition). A science textbook with creationist sympathies would be a valuable contribution. This book, although many will find it useful, comes short of the goal. Published in Origins v. 4, n. 1.
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 tiny marine worm, Spirorbis, constructs a calcareous tube, and is often found attached to shells and debris in the ocean. Fossil Spirorbis are sometimes common in coal beds. Some have suggested Spirorbis lived in fresh-water habitats in the past, but this is highly unlikely. It is more likely that coal formed in marine waters during the Flood.

Growth lines found in several invertebrates show promise of serving as a basis for many avenues of investigation. Their value as an independent method for geochronometry is presently questioned, while other methods of using them are being developed. Published in Origins v. 1, n. 2.
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. Published in Origins v. 1, n. 2.
