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.

本论文将沉积学、地史学、构造地质学、地球物理、构造几何学和运动学、板块构造等多学科有机的结合，以济阳坳陷为研究对象，采用各时期断裂分期配套，分析了不同构造运动时期济阳坳陷断层展布，进行构造运动学讨论；利用构造沉降史模拟与中生代断层上下盘剥蚀关系的恢复，探讨了中生代断裂活动的特征。

陆区上地层-沉积特征以及模式可以作为模型应用于海区中生界相关研究，对南海北部中生界油气勘探具有指导意义。

During the early stage of Yanshan Movement in the Mesozoic Era, when the North China Plate had completed joining the Yangtze Plate to become a new united Craton massif, the tectonic movement turned to intracontinental orogenic stage, resulting in widespread magmatic activity and migmatization so that Tianzhu granitic batholith intruded the area on a large scale to form an embryo of the granite peak forest in the Tianzhu mountain area and ultrahigh pressure metamorphic zone further retraced its way, and consequently outcropped on the crust surface.

中生代燕山早期，华北、扬子板块已完成对接拼合，形成了新的统一的克拉通地块，构造运动已转入陆内造山阶段，引起广泛的岩浆作用和混合岩化作用，天柱山花岗质岩基大规模侵入，形成了区内天柱山花岗岩峰林胚胎，并导致超高压变质带进一步折返，并最终出露地表。
