摘要
裂变径迹分析是六十年代初提出的一种地质年代测定方法.过去几十年来,它在更普遍的地质问题上的应用有了很大的扩展,这反映了对裂变径迹退火温度依赖性和裂变径迹长度分布信息的理解.裂变径迹分析岩石的低温热历史提供了详细的信息,在120℃以下,提供磷灰石的轨迹,在350℃以下,提供锆石轨迹.裂变径迹分析已应用于各种地质问题,包括沉积物源、沉积盆地热历史模拟、造山带构造演化和长期大陆剥蚀.
Fission track analysis is a geological dating method proposed in the early 60 s. It has greatly expanded its application in more general geological problems in the past few decades.This reflects the understanding of the temperature dependence of fission track annealing and the fission track length distribution information. The fission track analysis provides detailed information of thermal history of rocks under low temperature,providing apatite trajectories below 120 degrees Celsius and providing zircon trajectories at temperatures below 350 degrees Celsius. Fission track analysis has been applied to a variety of geological problems,including sediment sources,sedimentary basins,geothermal history modeling,tectonic evolution of orogenic belts,and long-term continental erosion.
