| 摘 要： | 本文结合笔者对大兴安岭和燕山中生代陆内造山作用的研究，对张文佑先生提出的“断块构造”的力源机制作进一步的探讨。大兴安岭中生代不同深度的两种作用同时控制着岩浆活动和构造变形，即软流圈底辟体上涌与陆缘剪切走滑的共同作用--可称之为构造-岩浆活动的二元机制，其中前者起主导作用。燕山地区中生代的断陷和隆起，是在岩石圈断裂继承性活动的基础上，在地幔物质上升和参与的背景下发生的，其中深部作用也是主导性的。

| Abstract: | Mechanisms of fault block tectonics，which was put forward by Prof. Zhang Wenyou，is reviewed in this paper on the basis of the authors researches on Mesozoic intracontinental orogeny of Da Hinggan Mts. and Yanshan region. Mesozoic tectonic deformation and magmatic activities of Da Hinggan Mts. are simaltaneouly controlled by two effects at different depths，ie. upwelling of diapers of asthenosphere and shear strike slip of continental margin，which compose a binary mechanism and of which the former is primary. Fault subsidence and upwelling of Yanshan region occurs as posthumous movements of lithospheric faults agaianst a background of upwelling and soaking of mantle materials，which are also deep effects and primary in the process. |
