摘要
矿区为多旋回构造变质、岩浆侵入活动区,并处于老君山锡钨(铋)锌多金属成矿区的北西端,在该成矿带内已发现众多大中小型铜、铅、锌钨、锡矿床,成矿条件优越.前期岩浆活动和构造运动频繁,为铜多金属矿形成提供了物质来源和热源,使矿区内多次成矿作用叠加.在矿区东及东南出露燕山期花岗岩,并在钻孔工程中发现矽卡岩,在岩体接触带上找矽卡岩型矿体具有较好的找矿潜力.
Abstract
The mining area is an active area of multicycle structural metamorphism and magmatic intrusion,and it is located at the northwest end of Laojunshan Sn-W(Bi)-Zn polymetallic metallogenic belt.Many large,medium and small copper,lead,zinc-W and tin deposits have been found in this metallogenic belt,and the metallogenic conditions are superior.The frequent magmatic activity and tectonic movement in the early stage provided the material source and heat source for the formation of copper polymetallic de-posits,which made multiple mineralization in the mining area superimposed.Yanshanian granite is exposed in the east and southeast of the mining area,and skarn is found in drilling engineering.Finding skarn-type ore bodies in the contact zone of rock mass has good prospecting potential.
