龙门山处于青藏高原东部边界,通过科学家和地质勘探者们对于野外地质的详细考察和准确的地震剖面构造的分析,发现并总结出了龙门山前带北带断褶的基本特征及其构造的特点,即龙门山系在扬子地台内新生出的断褶活动而形成的山系。并且发现了龙门山系山川西断陷区是属于龙门山系的盆地,是地台型海相沉积与前陆型陆相沉积组成的复合型油气区。
Longmen Mountain is located on the eastern boundary of the Qinghai-Tibet Plateau. Based on the detailed investigation of the geology of the geology field and the analysis of the accurate seismic profile structure, the basic characteristics and structures of the northern fold belt in the Longmen foreland belt are found and summarized Characteristics, that is, the Longmen Mountains in the Yangtze Delta platform for the new breach of the formation of mountain activities. It is also found that the Longmenshan system is a basin belonging to the Longmenshan system and a composite oil and gas area consisting of platform-type marine facies and foreland-type continental deposition.
