广东省地处东亚大陆新华夏系第一沉降带、第二隆起带和第二沉降带的西南端,同时又是南岭东西向构造带和我国南方较发育的南北向构造带纵横穿越的地段。因此,新华夏系构造、东西向和南北向构造是广东境内显示的最为强大和活跃的构造,它们共同组成了广东省构造体系的骨架,对中生代和古生代煤系的分布起着明显的控制作用。一、构造体系与中生代煤系中生代煤系包括上三迭统艮口煤系(小云雾山煤系)和下侏罗统金鸡煤系。中生代煤系发育在晚古生代凹陷和一些较老地层的结晶基底之上,显示为断陷带的产物。这些断陷带由
Guangdong Province is located on the southwestern tip of the first subsidence zone, the second uplift zone and the second subsidence zone of the East China New China. At the same time, it is also a section of the Nanling east-west structural belt and the more developed north-south structural belt in southern China. . Therefore, the structure, east-west and north-south structures of the Neo-Cathaysia are the most powerful and active tectonic structures in Guangdong. Together they form the framework of the tectonic system in Guangdong Province and play a significant role in controlling the distribution of Mesozoic and Paleozoic coal measures . First, the tectonic system and the Mesozoic coal measures Mesozoic coal measures include the Upper Triassic Genkou coal series (Xiaoyunwu Mountain coal series) and the Lower Jurassic Jinji coal series. The Mesozoic coal measures developed above the crystalline basement of the Late Paleozoic depressions and some older strata and appear as products of fault zones. These rupture belts are made of
