摘要
多拉纳萨依金矿横穿别列则克河而位于砂金矿区上游,其表层氧化带厚约30m.结构疏松,含金石英脉呈破碎状穿插于氧化带.是别列则克河砂金矿的主要物质来源.
Dolanasayi gold deposits crosses the bilizik river, locates the upper of the Area of theGold-placer. About 30m of the surfacc layer of the Oxidized Belt, the structure of rocks isloosed, gold-containing quartz-veins are broken, but with their original states. The gradeof the oxidized belt is higher than its original deposits'. The alluvial sediments whicharound the gold deposits contain placer-gold but their grades are very low. In the BilizikRiver, placer-gold becomes enrichment. Having studied the shapes, sizes of the golds and their change, the companied mineralswhich in the oxidized belt of the gold deposits, in the streams around the deposits, in thebilizik River, we concluded that the oxidized belt of the Dolanasayi Gold Deposits is themain source of the Bilizik River Gold-placer.
