摘要
主要介绍了磷灰石裂变径迹分析法、沉积波动过程分析法和宇宙成因核素分析法等3 种恢复和计算地层剥蚀量的新方法。它们的优点是不但给出一个剥蚀面造成的地层总的剥蚀量,还能详细刻画整个剥蚀过程,从而能计算出每一期构造抬升引起的地层剥蚀量。
The Apatite fission track analysis, the deposition erosion process analysis and the cosmogenic nuclide analysis are introduced as the three new advancing methods on the recovery of the thickness of eroded strata in basin in this paper. The three new methods have the common advantage, that is: not only the general thickness of eroded strata can be obtained, but also the whole erosion process be obtained. So the thickness of eroded strata occurring in every tectonic elevated erosion period can be easily recovered by means of the new methods.
