云南省蒙自县老寨街银多金属矿区找矿远景分析

Analysis of prospecting potential for Laozhaijie Silver Polymetallic Ore District in Mengzi County,Yunnan Province

老寨街矿区地处滇东南钨锡多金属成矿带,其外围已发现了多个铜、锌、银等多金属矿床。通过分析矿区的成矿背景及地质特征,对比周边矿床的成矿条件,结合以往的化探成果,对该区的成矿优势进行了分析总结。初步认为该区具备形成铜、锌、银矿床的基本条件,成矿及找矿前景极为优越,并圈定了三个找矿远景区。

Laozhaijie ore district is located in the tungsten-tin polymetallic metallogenic belt in the Southeast of Yunnan,and a plurality of Cu,Zn,Ag and other polymetallic ore deposits were found around the place.According to the metallogenic background and geological characteristics of the mining area,through some comparisons with metallogenic conditions in the surrounding areas,and combined with previous geochemical exploration achievements,this paper analyzes and summarizes the metallogenic superiority in this region.It tentatively suggests that the area has the basic conditions for the formation of Cu,Zn,Ag deposits,and its mineralization and prospecting foreground is superior.At the same time,three prospecting areas are delineated.
