马拉乌铅锌矿床为印度尼西亚西加里曼丹(Kalimantan)省吉打邦县近年来发现的铅锌银矿床。该矿矿体顶板为黄铁矿化含碳质泥砂岩,矿体底板为玉髓状硅质岩。矿体呈侧羽状、脉状及透镜状。矿区通常发育的蚀变有硅化、泥化和绿泥石化等。主要矿物组合有方铅矿、闪锌矿、黄铁矿、磁黄铁矿、黄铜矿、斑铜矿、辉锑矿以及自然金、银金矿、辉银矿等,通过对矿石组构等综合分析,表明该矿床的成因是岩浆期后热液充填交代矿床。
The Marau lead-zinc deposit is a lead-zinc-silver deposit discovered in recent years in the state of Kedar state in Kalimantan province, Indonesia. The ore body roof is pyrite carbonaceous silt sandstone, the ore body floor is chalcedony chert. Occidental pinnacles, veins and lenticular. Alluvial deposits commonly developed in the mining area are silicified, muddy, and chloritized. The main mineral assemblages are galena, sphalerite, pyrite, pyrrhotite, chalcopyrite, bornite, stibnite and natural gold, silver and gold, And other comprehensive analysis shows that the genesis of the deposit is hydrothermal filling metasomatic deposits after the magmatic period.
