摘要
湘粤两省上古生界以上的沉积盖层中普遍发育有伸展型、挤压型和重力型的滑脱断层。这些不同类型的滑脱断层相互转化、叠加与复合，构成了伸展－逆冲、伸展－重力、伸展－逆冲－重力、伸展－重力－逆冲和重力－逆冲５种不同样式的叠加型滑脱构造。这些构造的研究不仅在理论上充实了煤田地质学构造模式；更在实践方面为我国南方缺煤省分的找煤工作开辟了新的方向。
Extensional,compressive and gravitational gliding types of detachment faults developed widely in depositional overburden before the Upper Paleozoic Erathem in Hunan and Guangdong Provinces,which formed five types of structures through mutual conversion,superimposition and compounding.They are extensional thrust,extensional gravitational gliding,extensional thrust gravitational gliding,extensional gravitational gliding thrust and gravitational gliding thrust types of tectonics.These structures not only enrich the theory of structure models in coal geology,but also show a new approach for finding coal in coal deficient provinces in South China.
