成岩参数变化在构造作用研究中的应用

本文提出了成岩参数变化在构造作用研究中应用的４个理论基础，首次将构造作用，岩性和成岩作用有机地结合起来。构造－岩相理论认为构造作用控制岩性分布，而不同的岩性其成岩作用也有所差别，构造抬升使已成岩的地层遭受剥蚀或大气水淋滤而对成岩参数产生的一定影响，局部的构造活动也会导致相同层位的岩石产生成岩程度的差异。

APPLICATION OF CHANGES OF DIAGENETIC PARAMETER IN THE STUDY OF TECTONIC ACTIVITIES

This paper presents four theoretical fundamentals of the application of changes of diagenetic parameters in the study of tectonic activities. For the first time tectonic movement, lithology and diagenesis are closely related together. The structure-lithofacies theory holds the view that tectonic movement controls the distribution of lithofacies, and the authors believe that diagenesis varies with the lithologies. Erosion or meteoric leaching caused by tectonic elevation may exert certain influence on diagenetic parameters, and local structural activity may also lead to the difference in diagenetic degree of rocks in the same horizon. On the basis of the abrup't changes of some parameters and the great difference of diagenesis, the authors infer that tectonic activity might have occurred. This is in good agreement with the study of diagenesis of the following strata: (1) the Jurassic in Shanle oilfield, Turpan-Hami Basin, (2) the Eogene in the Dongpu depression, (3) the Eogene Dongying Formation in JZ20-2 structure, Jinzhou, Liaodong Bay area, and (4) the Neoproterozoic Xiamaling Formation in Pingquan, Hebei Province.
