都龙矿床是滇东南三大多金属矿床之一。前人对该矿床的成矿特征、成矿规律与控矿因素、成矿时代以及岩浆作用等方面进行了大量的研究,积累了丰富的资料。地质事实和已有研究表明,该矿床具有明显的构造控矿特征,但矿区构造的研究相对薄弱,特别是对以矿区F_0、F_1、F_2等3条主干断裂为代表的、具有重要控矿意义的N-S向断裂构造在成矿前后的演化过程认识还不够清晰。在野外调查和综合研究的基础上,解析了燕山晚期花岗岩成岩-成矿事件前后N-S向断裂构造的演化过程,刻画了该组断裂在不同时期的力学机制及其动力学背景,探讨了该组断裂构造的控矿意义,认为该组断裂构造不仅是含矿热液运移的通道,还是含矿热液交代、沉淀成矿的场所,起到了导矿、容矿的作用。根据上述认识,提出上述3条断裂经过的、勘查工作相对薄弱的水硐厂、五口硐、烟山等矿区,是寻找锌、铅、银等多金属矿的有利靶区。
Du Long ore deposit is one of the three major polymetallic deposits in southeast Yunnan. The predecessors made a great deal of researches on the metallogenic characteristics, metallogenic regularity and ore-controlling factors, mineralization age and magmatism of this deposit, and accumulated rich data. The geological facts and the existing studies show that the deposit has obvious tectonic ore-controlling characteristics, but the research on the tectonics is relatively weak, especially for the three main faults, such as F_0, F_1 and F_2, which have important ore-controlling significance The NS to the fault structure in the evolution of understanding before and after the mineralization is not clear enough. Based on field investigation and comprehensive study, the evolution process of NS-trending faults before and after diagenesis-mineralization event of Yanshanian granite was analyzed, and the mechanical mechanism and dynamic background of the faults in different periods were described. It is considered that the fault structure of this group is not only a passage for ore-bearing hydrothermal migration, but also a place where ore-bearing hydrothermal fluids are exchanged and precipitated for mineralization, which plays a role of guiding ore and mineralizing. Based on the above understanding, it is proposed that the above three water breakthroughs, such as Shuidongchang, Wuadong and Yanshan, whose exploration work is relatively weak, are favorable targets for finding zinc, lead and silver polymetallic mines.
