摘要
Several tin polymetallic geochemical anomalies have been found in Dazhou basin,which is located between Lingshan~Tengxian county and Bobai~Wuzhou regional deep faults during 1/200000 stream sediment survey,with Sn as major anomaly,associated W、Au、Ag、Pb、As、Sb、Bi.The anomalies are characterized by planar distribution with evident center concentration and concentration zoning.Some anomalies were testified by 1/10000 soil survey and anomaly reproduction was good.Several tin orebodies has been found by trough and drilling tests.The ores occur in purple to red gravel bearing inequigranular sandstone,iron bearing shale,lean hematite layer and fracture zone in the rock of lower part of Jurassic paradise group.Based on the summary of ore controlling factors and ore prospecting indicators in Periphery of the basin,it is concluded that the prospects for "Rongtang"type tin deposit and tin polymetallic deposit searching is hopefull along the continent edge of the basin.
