| 摘 要： | 三山岛金矿床和焦家金矿床虽然均为“焦家式金矿”的典型代表，但两者的矿物共生组合、载金硫化物矿物成分特点、金矿物的成色，以及围岩蚀变类型、强度，矿化阶段的发育情况等都有明显的差异。三山岛金矿床的毒砂、砷黝铜矿含量较高，黄铜矿的Cu／Fe、方铅矿的Pb／S也较高。这些特征与三山岛金矿的多金属硫化物阶段更发育的事实一致，反映了该矿床可能在矿床(或矿体)分带方面表现了比焦家金矿较浅部较外围的特征，这对深部远景具有指示意义。

| Abstract: | The Sanshandao and the Jiaojia gold deposits are quite different in mineral assemblage, composition of gold-bearing sulfides,purity of gold minerals,types and intension of wallrock alterations as well as mineralization stages. Arsenopyrite and erythroconite are common in Sanshandao deposit. The Cu/Fe ratio of chalcopyrite and Pb/S ratio of galena in the Sanshandao deposit are higher than those in the Jiaojia deposit, being in accordance with the developed polymetallic sulfides in the Sanshandao deposit,and showing superficial zoning of orebodies in peripheral portion related to the Jiaojia deposit. It is very significant for deep prospecting. |
