黑龙江老柞山金矿主要载金矿物的标型特征

The typomorphic characteristics of the main gold-bearing minerals in Laozuoshan Gold Deposit, Heilongjiang Province

老柞山金矿由早、晚两期成矿作用形成 ,其中早期由三个成矿阶段、晚期由四个成矿阶段构成。金矿的主要载金矿物分别为 :毒砂、磁黄铁矿、黄铁矿、方铅矿和闪锌矿。本文从形态、成分、含金性、热电性等各方面分别对不同世代的五种载金矿物进行研究 ,从而得出了老柞山金矿床主要载金矿物的矿物学找矿标志。

The Laozuoshan gold deposit is formed in two mineralization processes . The early process is consisted of three stages , and the late one four stages . The main gold bearing minerals include arsenopyrite , pyrrhotine , pyrite , galena and sohalerite . This paper has found the mineralogical prospecting typomorphic characteristics of the main gold bearing minerals in this deposit by the researching of these minerals in crystal forms , composition , auriferous characteristic.pyroelectricity etc .
