摘要
磷灰石中封闭径迹长度分布能提供很好的热历史信息。我们测定了取自临清拗陷石油探井不同深度的岩芯中的磷灰石封闭径迹长度分布,并根据该长度分布和裂变径迹年龄分析了热历史。对关于磷灰石中古裂变径迹退火的径迹密度和径迹长度之间的关系也进行了讨论。
Length distributions of confined tracks in apatites collected from the cores at various depths of exploratory boreholes in the Lirqing Sedimentary Basin were determined and thermal histories were analysed on the basis of the distributions and fission, track ages. The relationship between track de'sity and track length for annealing of fossil fossion tracks in apatites was discussed as well.
