The Maguan Long Man Luojiazhai, Tin Zinc Deposits In The Peripheral Mineralization Forecast,

DuLong mining area in Yunnan is located at the west-south of LaoJun mountain in southeast of Yunnan Province, it is belong to DuLong town,Maguan County,the Wenshan autonomous prefecture of Zhuang national minority and the Miao national minority. It is another ultra-large tin zinc polymetallic ore deposit except Gejiu Yunnan and DaChang Guangxi.The Limited liability company of HuaLian zinc and idium YunNan,is a integrated enterprise which product non-ferrous metal include pincking,choosing and smelting, the main mining object is the polymetallic ore deposit of tin-zinc in Man JiaZhai DuLong. In order to expand the amount of resources and extend the service life of mine, needs to strengthen the mineralization forecast research at the mine depth portion and the periphery.This article research from foundation geology, through to the key dissection of various types ore deposit include Man JiaZhai, TongJie, Shui DongChang, XinZhai, Nan Yangtian and so on. Then strengthens the mineralization forecast research by carring on statistical and superposition the information of geology, through to researching the feature of ore deposit geological, the characteristic of geochemistry, the ore-control factor of the ore deposit,analyzing the symbol of prospecting, integrating the geochemical and applying mathematics geology as well as the mining software.Unifies predecessor's data and our newest date which get from the open country geological investigation, mainly yields following result:No1. Had widely discovered basic volcanic rock from the stratified skaro and the massive sulfide ore body through to determination of thin section. Thought the protolith of skaro is the basalt and the tuff, so thought the protolith of skaro is the basalt and the tuff. Had the test data through the field observation union, thought the LaoJun mountain area of mineralization in the deep depression area of Galedomian period and had the sign of volcano eruption sedimentary in Cambrian period.No2.Analyzed the sulfur isotope had discovered the sulfur source of the ore deposit mainly comes from the mantle, it is possibly suggests the mineralization had the relation to the volcano eruption sedimentary; discovered the superficial age of lead is quite big through to analyzing the lead isotope, it showed the mineralization hasd experienced the multi-times and the multi-stages in the LaoJun mountain area, it is a multi-origin compound ore deposit. It has experienced the stage of the volcano eruption sedimentary - the stage of the new metamorphic focusing in this region - the stage of supraposition of magmatic hydrothermal and enrichment mineralization.No3.At last we had pointed out 4 optimal prospecting area to the researching to the ore deposit about the origin and the geochemical,analyzed the rule of ore-control and summarized the symbol of prospecting.
