摘要
Low-temperature thermochronology based on the isotopic chronology analysis is the most important tecton-thermal chronology dating method and is the most important branch and forward field of geochronology study.The research field mainly focuses on fission track dating and(U-Th)/He dating.The advance of low-temperature thermochronology in recent years is introduced firstly.Then,taking Dangyang synclinore and Jingshan region,mid Yangtze area for example,the application of low-temperature thermochronology to tecton-thermal history analysis of superimposed basins is discussed.The analysis results show that the dating indicators of different types of low temperature thermochronology can effectively constraint the tecton-thermal evolution process of a geological body when the paleo-temperature is <240℃.This gives a quantitative low temperature thermochronology evidence for studying tecton-thermal history of superimposed basins.
