摘要

摘要: 磷灰石裂变径迹与结晶C轴平行的、与抛光面相交的裂变径迹蚀刻象的最大直径D_par可以较好地反映磷灰石颗粒的裂变径迹的退火行为.按照D_par的不同,将同一样品各个磷灰石颗粒的径迹分成几个具有不同动力学性质的成分,然后对这些成分多元动力学成分模拟,使原先"单一"的磷灰石时钟体系变成由若干个独立的热时钟构成的体系,这些独立的热时钟分别记录了样品通过不同温度段的历史,由它们综合而成的历史就更为全面、可靠.本文最后介绍了来自4个盆地的样品的模拟结果.

Abstract: A new parameter,D_par,which is the arithmetic mean etch figure diameter parallel to the C-axis at the etched surface,can describe effectively the annealing behavior of apatite fission tracks.Apatite grains from a single sample can be divided into different kinetic populations according to their measured D_par values.The time-temprature history modelling based on apatite fission track data can therefore be developed into a multikinetic modelling system consisting of several independent apatite thermochronmeters.Consequently,the modelling result is more practical and accurate.Four examples from different Chinese sedimentary basins are shown at the end of the paper.
