摘要
研究区位于苏、鲁、豫、皖交界中心,大地构造隶属于华北板块东南缘,是华北地区主要赋煤地带,自石炭—二叠纪以来,该区经受了多次构造活动,构造演化与华北板块南缘和东缘的2条板缘构造活动带密切相关。通过在研究区进行野外实际调查并结合区域地质资料的基础上,对研究区地质构造特征及其演化进行了讨论,并探讨了研究区构造对煤田的控制作用。
The study area was located in the bordering center of Jiangsu-Shandong-Henan-Anhui provinces ; its tectonic unit belonged to the southeastern margin of the North China plate and was a major hosting coal belt in North China. Since Permo-Carboniferous, this area underwent a multiphase tectonic activities, tectonic evolution was closely related to the two tectonic activity belts on plate margin of the south and east margin of the North China. Based on a systematic analysis of the geological data in the study area and in combination with the field survey, the authors discussed in details the characteristics of geology tectonic characteristics and tectonic evolution, studied its controlling effect on coal field occurrences in Xu-Su area.
