摘　　要：铜街-曼家寨矿段位于文山老君山花岗岩体南西端的都龙锡锌矿带,矿段内赋存由加里东期志留纪花岗岩的侵入产生的热变质作用形成的干矽卡岩及经过燕山期花岗岩侵入产生的接触交代变质作用形成的湿矽卡岩。文章对铜街-曼家寨矿段矽卡岩进行了科学实验,并对其元素富集规律、品位变化特征行了研究总结。Located in the Dulong Sn-Zn ore belt at the southwestern end of the Laojunshan granite batholith in Wenshan,the Tongjie-Manjiazhai mining section hosts dry skarns formed by thermometamorphism due to the intrusion of Silurian granites during the Caledonian period,as well as wet skarns resulting from contact-metasomatism caused by the intrusion of Yanshanian granites.This paper presented scientific experiments conducted on the skarns in the Tongjie-Manjiazhai mining section,and summarized the concentration patterns of elements and features of grade variation.
