龙湾套铜矿岩石学特征及矿床成因

Origin of Longwantao Copper Deposit Based on Analyzing Petrological Characteristics

泗水县龙湾套地区发育大面积新太古代角闪辉长岩,为在该区寻找赋存在角闪辉长岩中的岩浆熔离型铜矿床,曾开展过普查工作,最终发现了一小型铜矿床。探讨该区角闪辉长岩岩石学特征,对在该区进一步寻找同类型铜矿床有重要意义。

There is a large area of Neoarchean hornblende gabbros in Longwantao area in Sishui county.In order to find magmatic liquation type copper deposits existed in hornblende gabbros,geological survey has been carried out,and finally found a small scale copper deposit.In this paper,petrological characteris-ticS of hornblende gabbros have been studied.It will have important theoretical and practical significance in searching the same type of copper deposits in this area.
