通过多年的钻探实践和前人的总结以及目前的研究认为:川西南地区阳新统缝洞的主控因素可以归纳为岩溶、构造、断层作用。这三种作用是形成阳新统缝、洞系统最重要的因素。在不同的构造、不同的地区,可表现出以某一、二种因素为主导,三种因素所占比重可不尽相同。
Through many years of drilling practice and predecessors’ summary and current research, it is concluded that the main controlling factors of the Yangxindong fault caves in southwestern Sichuan can be summarized as karst, tectonics and fault. These three kinds of roles are the most important factor for forming the Yangsian seams and cave systems. In different structures and different regions, it can be shown that one or two factors are dominant, and the proportions of the three factors may vary.
