摘要
This article choosed Fanjiacun profile in Lintong-chang’an fault as a typical fault gouge samples testing and used three different methods to obtain nine different age data. According to stratum information and minerals luminescence growth curve, the paper determined only three dating method. They are mixed minerals multiple aliquot regenerative dose protocol, fine grained quartz multiple aliquot regenerative dose protocol and fine grained quartz single aliquot regenerative dose protocol. These fault wedge ages are close to collapse product of surrounding rock formation age but can’t represent real fault activity era. So we conclude that optical stimulated luminescence age results of colluvial deposit can’t give real activity age about fault.
