中文摘要:兰坪金顶超大型矿床各种角砾岩和角砾岩型矿体十分发育，通过对角砾岩型矿体形态、产状、与围岩接触关系和角砾岩自身结构特点的研究，作者首次发现并提出灰岩角砾岩型矿体是一种侵位角砾岩，其形成机制类似于现代泥火山。
Abstract:There are many breccia_type orebodies in the Jinding lead_zinc ore district, in which the authors found for the first time intrusive breccia_type orebodies. Studies show that the original rock of the limestone breccia_type orebody is a kind of intrusive breccia. Instead of a kind of Paleocene continental sedimentary breccia, it is a half_fluid mixture of oil, lead_zinc carbonate and gypsum_solution rubbles, and its origin is similar to that of modern mud volcano. The longitudinal axial fracture zone of Lanping basin is a mud_volcano conduit, and the intrusive breccia type lead_zinc orebody with “concrete characteristics” was formed in the upright fractural zone of Jinding district.
