METHOD OF “RECOVER LAYER BY LAYER” FOR CALCULATING THE PALEOTHICKNESS OF SEDIMENTARY LAYER

This paper describes the principle of the method by "recover layer by layer" for calculating the palaeothickness of sedimentary layer, and the applications and problems existed so far. The method of "recover layer by layer" is established on the concept of compaction of sedimentary layer, which applied the principle hypothesis that the solid height of sedimentary layer is not changed during the compaction. The thickness of sedimentary layer deposited in various geological periods could be recovered by calculating the solid height of sedimentary layer. The further calculations for compaction capacity, different compaction capacity, and changed value on the base boundary of sedimentary layer,the different compaction structures then could be analysed.
