After crystallization basement was formed in Tai Shan group in the end of Archaean, it suffered long term denudation and deposited to marine and land interbedded formation with stable lithology and thickness. Buried Hill is a large size fold nappe which was uplifted, compressed, folded, denudated and settled in Indosinian period, deposited in Mesozoic formation, then wholly advanced to the west in the late of Yan Shan movement. The force acting on internal structure of buried hill was complicated, and fault block was broken up.

本文通过物探、测井二次解释和钻井等大量资料的研究认为：桩西古潜山在太古代末期泰山群形成结晶基底后，遭受长期剥蚀，在古生代沉积一套岩性、厚度稳定的海陆交互相地层，是一个经印支期抬升、挤压、褶皱、剥蚀、沉降接受中生界地层沉积之后，在燕山运动后期，整体向西推移的大型褶皱推覆体。

In this dissertation, sedimentology, historical geology, structural geology, geophysics, structural dynamics/geometric, plate structure etc were combined properly. Taking Jiyang depression as studying object, fault distribution of different periods was analyzed, and thus discussing their structural dynamics. Using tectonic subsidence history modeling and denudating relationship between hanging wall and foot wall in Mesozoic faults, fault activity characteristics were discussed.
