Some Questions about Geochronology

The geochronological time scale of thousands of millions of years is based mainly on radiometric dating. On the other hand, some other time-dependent processes change at rates which challenge generally accepted geochronology. Published in Origins v. 13, n. 2.

How Solid is a Radioisotope Age of a Rock?

Radioisotope ages are calculated from ratios of certain atoms. The isotopic ratios can be precisely measured, but the calculation of age from that ratio involves assumptions that may vary depending on the philosophical orientation of the investigator. Published in Origins v. 10, n. 2.

Geo and Cosmic Chronology

The picture that emerges from all the data that relate to cosmic chronology appears to be one of dynamic physical processes operating over extended periods of time, during the last 4.5 billion years of which discrete entities of the Solar System have been in existence. This suggests the word "earth" in Genesis 1 may refer to the land surface of the planet, and not to the planet itself. Published in Origins v. 8, n. 1.

The Interpretation of C-14 Dates

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.

Radiometric Age and the Traditional Hebrew-Christian View of Time

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.

The Impact of Tektites upon an Estimated 700,000 Year History of Deep-Sea Deposits

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.

C-14 Age Profiles for Ancient Sediments and Peat Bogs

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.

Literature Reviews

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.
