摘　　要：晴隆沙子红土型金、银矿产于碧痕营穹窿状背斜北西翼,矿床由3个矿体组成,分布于茅口灰岩喀斯特负地形的第四系松散堆积物中。矿体呈似层状、透镜状及漏斗状产出,厚4.50-43.00 m,平均厚17.4 m.矿床的形成经历了矿源体形成期和表生作用成矿期,初步认为是喀斯特崩塌堆积红土型及原地残积红土型金、银矿床。Shazi lateritic gold and silver deposit occurred in the northwest flank of dome anticline in Bihengying,is made up of three orebodies,distributed in the quaternary unconsolidated accumulative material of Maokou limestone negative relief.The orebody is occurs of layer,lentoid and funnel-shaped,the thickness is 4.50 to 43.00m;the average thickness is 17.4m.The formation of the deposit experienced the mineral resource formation period and epigenesis metallogenic epoch.It＇s thought that it is karst collapse accumulative lateritic and onsite sedentary lateritic gold and silver deposit.
