摘要

The thermal Kaiser effect suggests that rock can record the information of the highest temperature that it has experienced in the geologic history. And the highest temperatures of sandstone and mudstone samples with different buried depths in the Tarim Basin and a sample in western Sichuan Province were carefully measured. The results illustrate good thermal Kaiser effect and the rock thermo-acoustic emission signals vary with temperature. Temperatures measured by thermo-acoustic emission are largely consistent with the highest temperatures samples experienced, suggesting the thermo-acoustic emission can be applied to paleogeotemperature measurement.
