摘要

本文针对盐湖盆地地层结构特点,采用一种沉积物厚度去压实(古厚度计算)的改进算法,考虑了由剥蚀作用、盐运动及互层引起的厚度和埋深变化。根据岩层现今厚度、岩性、剥蚀厚度、异常压实及盐层厚度的变化,计算各地层时代末期的古厚度。这将为准确进行盐湖盆地埋藏史分析,构造演化分析提供重要途径。

Abstract

An improved backstripping inversion method of original stratum thickness was applied to Wuyang salt basin.The method considered erosion,salt movement,interlayerd bedding,and abnormal compaction in the basin.By using this method we can calculate the original stratum thickness and lithologic proportion in every sedimentary telophase based on nowadays stratum thickness,lithologic proportion,abnormal compaction,and salt thickness,which is very important to embedding history analysis and tectonic evolvement analysis in salt basin.
