| 摘 要： | 本文详细分析了两淮煤田地层接触关系及各种形式构造的分布,认为该区构造形变可以分为三个阶段:印支南北向压性期;燕山北东向左行压扭构造形成期;喜山全区拉张活动期。第二阶段构造形成在岩浆作用之前或同时,与有机质再次热演化配合得较好。

| Abstract: | Detailed analysis is made of the interstratified relationships and the distribution patterns of geological structures in Huainan-Huaibei Coalfield, and a conclusion is arrived at that the structural variations in this area are results of three phases: northward Indo-Chinese copression phase, northeastward Yanshan left - contorted structure formation phase, and Himalayas region-wide tensile activity phase. Structures in the second phase, i.e., the phase of Yanshan Movement, were formed before or at the same time as magmatism, at a time when a reproductive thermal evolution of organic substances was occurring |
