云南开远妈达铜多金属矿矿床成因及找矿标志

Reason of Ore Deposits and Prospecting Sign of the Mada Copper Ore Deposit Kaiyuan in Yunnan Province

云南省开远市妈达铜多金属矿地处中山峡谷等复杂地形地带,呈中山山地高原地貌。该矿区处于陆地,侵蚀作用明显,卡斯特地貌发育良好。由于该矿区地形复杂,具有较好的成矿地质背景,早在解放前就对该矿区的周边做了一些地质考察工作,形成了一些零星的资料。本文结合前人所做工作和本次工作,对本矿区的矿床成因进行了分析,指出了本矿区的主要找矿标志。

Mada copper polymetallic deposit of Kaiyuan Yunnan province is located in the nanpan river with its tributaries and deep and complex terrain, such as zhongshan canyon, moderate shallow cutting zhongshan mountain plateau landform. Because of the region land for a long time, erosion, Custer landscape development, since the mine has been located in the complex terrain, with good geological background. Long before liberation was the individuals and units in the area of surrounding made some geological work and formed some sporadic data, so this was mainly combined with the previous work, the work of the ore deposit genesis was analyzed, and the main prospecting sings were pointed out.
