Why is u 238 used for dating rocks
However, careful examination of the papers they cite shows that this apparent agreement is the result of the typical uniformitarian circular reasoning.
Such results pose a serious challenge to uniformitarian assumptions underlying conventional radiocarbon age-dating methods. This deposit formed within just a few hours (Morris and Austin 2009, 50, 52–54). “A Novel Approach to Varve Counting Using μXRF and X-Radiography in Combination with Thin-Section Microscopy, Applied to the Late Glacial Chronology from Lake Suigetsu, Japan.” Quaternary Geochronology 13: 70–80. Likewise, interpretation of other rock units consisting of many thin laminations makes more sense if one assumes that the laminae were formed rapidly. 1997), although Nature did not acknowledge Berthault’s prior work (Snelling 1997). Furthermore, these experimental results have been confirmed by field observations. Helens subsequent to the well-known May 18, 1980, eruption resulted in the formation of a 762 cm (25 feet) thick deposit consisting of many thin, alternating fine-grained and coarse-grained laminae very similar to varves.
