| 摘 要： | 辽南碧流河中上游砂金矿位于营口—宽甸台拱与复州台陷的交接部位。砂金主要赋存于碧流河及其支谷水系第四系全新统砂砾石层的底部,砂金矿体平行河谷呈层状分布;矿体埋藏浅,砂金粒度中粗,易采选;属冲洪积型谷底砂金矿。本区砂金主要来源于岩金矿和含金地层,成矿物质丰沛,成矿地质条件优越,是辽南砂金成矿的远景区。

| Abstract: | The gold deposits in the middle-upper reaches of the Biliu river in Southern Liaoning is situated in the intersection of Yingkou - Kuandian palaeouplift and Fuzhou palaeodepression . Gold mainly exists in the bottom of Holocene gravel of the Biliu River and its tributaries . The deposits is bedded and distributed parallelly to the valleys . The placer , which is shallowly buried with the gold being meso -coarse grained , is easy to be mined and treated , it is an alluvial -deluvial -type gold placer in which the gold deposits in the bottoms of valleys .The gold was derived from gold-bearing rock and sedimentary strata . This area , where have abundant gold mineralised material and favourable geological settings , is a prospecting target area for gold placer in Southern Liaoning . |
