都龙锡锌多金属矿床是我国三大锡石硫化物矿床之一。在野外调查和综合研究的基础上,从规模、形态、分布、蚀变类型及成矿元素组合等方面总结了铜街-曼家寨矿段矿体的基本特征,并对层间剥离构造和岩浆侵入构造等两大构造体系进行了初步解析。认为都龙超大型矿床的形成是花岗岩、构造和地层等多种因素耦合的结果,燕山晚期老君山花岗岩及其热液作用是成矿的关键因素,层间剥离构造体系是成矿元素卸载的主要空间,田蓬组地层岩性组合为成矿元素的富集提供了有利的物理-化学环境。根据上述认识,指出铜-曼矿段深部及外围水洞厂-天堂坡一带具有较好的找矿远景。
Du Long Tin zinc polymetallic deposits is one of the three major cassiterite sulfide deposits in China. Based on field investigation and comprehensive study, the basic characteristics of the orebody in Tongjie - Manjiazhai ore section are summarized from the aspects of scale, shape, distribution, alteration types and the combination of metallogenic elements. The stratigraphic peel structure and Magma intrusion structure and other two major structural system for a preliminary analysis. It is considered that the formation of the Dulong superlarge deposit is the result of the coupling of various factors such as granite, tectonics and strata. The Laoshanju granite and its hydrothermal processes are the key factors for metallogenesis. The interlayer peel structure is the unloading of ore-forming elements The main space, the Tian Peng Formation stratigraphic lithology combination provides a favorable physical-chemical environment for the enrichment of metallogenic elements. Based on the above understanding, it is pointed out that there is a good prospect for ore prospecting in the vicinity of the water tunnel factory-Tian-tong-po in the deep part of the Cu-Man ore section.
