摘要
阿日特克山铜多金属矿床是近年来新发现的多金属矿床,已圈定铜矿体7条,多金属矿体(铜铅锌银)6条,钼矿体20条,金矿体2条。研究表明,该矿床为与隐伏花岗闪长岩关系密切的岩浆热液型矿床,受构造和围岩控制,在岩体内部、接触带等不同部位形成不同类型的矿体。铜和多金属矿体主要赋存于透辉矽卡岩中,为矽卡岩型矿体;钼矿体赋矿岩石为黑云变粒岩和花岗闪长岩,为岩浆期后构造热液型矿体;金矿体赋存于大理岩内部的层间构造破碎带中,为构造蚀变岩型矿体。
The Aritekeshan copper polymetallic deposit is a newly discovered polymetallic deposit.There are 7 copper ore bodies,6 polymetallic ore bodies(copper,lead,zinc and silver),20 molybdenum ore bodies and 2 gold ore bodies delineated in the mining area.The study shows that the deposit is a magmatic hydrothermal deposit closely related to concealed granodiorite,which is controlled by structure and surrounding rock and forms different types of ore bodies in different parts of the rock bodies and contact zones,etc.Copper and polymetallic orebodies are mainly found in the diopside skarn,which is a skarn-type ore body.The host rock of molybdenum ore bodies are biotite granulite and granodiorite,which are structural hydrothermal ore bodies in the late magmatic period.The gold ore bodies exist in the interlayer structural fracture zone inside the marble and is a structural altered rock type ore body.
