Cosmogenic exposure dating Text by Carrie Patterson, MGS. Cosmogenic isotopes are created when elements in e atmosphere or ear are bombarded by high energy particles (µ-mesons and protons, collectively known as cosmic rays) at penetrate into e atmosphere from outer space. Some cosmic ray particles reach e surface of e ear.  Measurement of a stream offset and cosmogenic dating ( Be) of e alluvial surface into which e stream incised yield a preferred late Holocene slip rate of 18.6 +3.5/−3.3 mm a −1 for e central part of e Nor Anatolian fault (NAF) at Tahtaköprü, Turkey. use of variable cosmogenic production rate (VPR) models yields a slightly slower rate of ∼16.4 +6.4/−4.5 mm a −1. Data given by Nishiizumi et al. (2000) and Berezhnoy et al. (20) for Los Angeles mostly agree well wi Be and 53 Mn data of KG 002, whereas e higher 26 Al activity of KG 002, in comparison.
