摘要
宁夏青铜峡市双圈铜矿矿体似层状赋存于上泥盆系上统中宁组第二岩段(D3Z)灰绿色砂泥岩中,矿体产状与岩层产状基本一致,矿床成因为淋积型铜矿床。有利的地层和岩性、构造条件及岩相古地理环境是主要的控矿因素,矿区内的孔雀石化、硅化、褐铁矿化、重晶石化是重要的找矿标志。
The Ningxia Qingtong Xia city shuang quan copper mine ore body resembles the layered tax to save in the second rock section of Zhongning Formation of Upper Devonian System(D3Z)greyish-green granulated substance mudstone,the ore body produces the shape to produce the shape basically with the rock layer consistent,ore deposit origin for illuviation copper ore deposit.The advantageous stratum and the lithological character,the structural environment and the lithic facies ancient geographical environment are main control the ore factor,in the mining area peacock petrify,the silicification,the ferritization,the barite are the important prospecting symbols.
