摘要
蒲塘金矿床属爆破角砾岩型。主成矿期温度２３６～３１８℃，主矿体受爆破角砾岩筒控制，含矿围岩蚀变及矿体变化规律明显。黄铁矿及黄铜矿是金的主要载体矿物。矿石中Ａｕ－Ｃｕ含量呈正消长关系。成矿物质主要来源于花岗岩。从花岗岩的侵入到矿床的形成，大体上经过了晚燕山期浅成初始岩浆侵入－爆破、超浅成强烈爆破及热液成矿三个阶段。
Putang gold deposit belongs to explosive breccia pipe type.Temperature of main mineralizational period is 236～318℃.Main orebody is controled by explosive breccia pipe.Wall rock alteration of the deposit and changes of orebodies have obviously regularities.Main Carrier minerals of gold are pyrit eand chalcopyrite.There is a positive correlation exist between the content of Au and Cu in the ore.Mineralizing material mainly come from granite.From the intrusion of granite to forming of deposit,it can be devided into three phases as follow:initial magma hypabyssal intrusion in Yanshan epoch,explosion and ultra hypabyssal intensely explosion,and hydrothermal deposition.
