淯溪断裂带五号断层铜多金属矿成矿规律

Study on Metallogenic Regularity of Cu Polymetallic Deposits of No. Five Fault in Yuxi Fault Zone

淯溪断裂带五号断层铜多金属矿产于断裂带上盘褪色白云质含砾次长石砂岩和白云质次长石砂岩中,为浅成中低温热液型矿床。根据五号断裂带延伸特征,及区域铜矿沿断裂近等距排列的特点,建议将五号断层南部作为下一步工作重点,综合研究其成矿时代及成矿物质来源。

Cu polymetallic ore of No.5 fault in Yuxi fault zone existed in fade dolomitic containing gravel subarkose and dolomitic subarkose hanging wall and footwall blocks of the fault,for the shallow low temperature hydrothermal type deposit.It is suggested that the south of No.five fault zone is the key point.The authors comprehensively study its ore-forming epoch and source of ore-forming material.
