由中国地质学会构造地质、地质力学专业委员会主办的“断裂构造”学术讨论会于1983年10月6日至12日在山西省大同市召开。这次会议主要讨论逆掩断层或推覆构造。会议内容表明,我国近几年来对逆掩断层、推覆构造及重力构造的研究,已取得了一批可喜成果。例如,在我国西部的准噶尔盆地西北缘、龙门山前、贺兰山前等许多地区都发现颇具规模的逆掩断层或推覆构造;在东部地区的秦岭、大别山、大青山、宁镇山脉等也都发现这类构造的存在。这些发现 The Symposium on “Fault Structure” hosted by the Committee of Geology and Geomechanics of China Geology Society was held in Datong, Shanxi Province from October 6 to October 12, 1983. This meeting mainly discusses the inversion of fault or nappe structures. The contents of the meeting show that in recent years our country has made a number of gratifying achievements in the research on the overthrowing fault, the nappe structure and the gravity structure. For example, quite a large scale of overthrusts or nappe structures have been found in the northwestern margin of the Junggar Basin in the west of China, the front of the Longmen Piedmont, and in front of the Helan Piedmont. In the eastern region, Qinling, Dabieshan, Daqingshan and Ningzhen Mountains are all also Find the existence of such structures. These discoveries
