本区指内蒙地轴之南,秦岭褶皱带之北,郯庐断裂带以西,吕梁山以东的大华北区。 研究华北地区的构造演化,离不开喜马拉雅运动及燕山运动,此乃公认之地质事件。而燕山运动之前中生代早期的印支运动在本区的影响及其表现形式如何?目前认识尚有分歧,关键在于有否印支褶皱运动,因它关系到在本区寻找古生代油气藏的问题。为此,根据本区多年来所取得的地质及地震资料,并结合燕山、山西及豫西地质资料的分析,在前人研究成果的基础上,对本区印支运动的影响及其表现形式作初步分
The area refers to the south of Inner Mongolia axis, north of Qinling fold belt, west of Tanlu fault zone and north of Lü liangshan. The study of the tectonic evolution in North China can not be separated from the Himalayan Movement and the Yanshan Movement. This is a recognized geological event. The influence of the Indo-Chinese Movement before the Yanshan Movement in the Early Mesozoic and its manifestations in the area before the Yanshan Movement are still unknown. At present, there are still differences in understanding. The key lies in whether the Indosinian fold movement is due to the problem of finding Paleozoic reservoirs in this area. Therefore, based on the geological and seismological data obtained over the years and the geological data of Yanshan, Shanxi and western Henan, based on the research results of previous studies, the influence of Indo-China movement in this area and its manifestations Preliminary score
