Description

An idea of "effective erasure depth（EED）" is introduced to confirm the so－called "zeroing" in TL dating of fault movement．EED is the depth from the grain surface to a boundary，outside／inside which the paleodose accumulated until faulting was completely／partially erased at the event． Applying this idea to TL dating of the Higashiura Fault，Awaji island in Japan， the zeroing of quartz was confirmed for fine grains collected from the highly and moderately fractured subzones，and the TL age of the fault movement was assessed as O．32±0．03Ma
