THERMOLUMINESCENCE AGES OF SOME QUARTZ IN FAULT GOUGES

Abstract

The quartz-inclusion method, which has been developed in the thermoluminescence dating of pottery, was applied to date some fault-crushed materials. In dating these samples, the blue and the infrared absorption filter were used. The seven samples of fault-crushed materials were collected from the areas along the Arima-Takatsuki tectonic line and the Yamasaki fault, Southwest Japan. Their thermoluminescence ages, which indicated the time of last heating over 230° of faulting, were dated, and the accuracy of thermoluminescence dating of faultcrushed materials was examined.
