    METALLOGENETIC AND GEOLOGICAL FEATURES OF WUFENG-WUXINGSHAN GOLD DEPOSIT IN JILIN PROVINCE

    • 摘要: 五凤一五星山金矿床属中生代陆相火山岩浅成热液型金矿床。侏罗系上统金沟岭组火山岩为其主要矿源层,矿体受火山机构的断裂、裂隙和次火山岩脉内外接触带的控制。碱长花岗岩侵入金沟岭组底部位,为金矿形成提供了主要热源。成矿作用主要进行于低压、中性介质和弱氧比、超浅成条件下。金矿一般富集于如下部位,即矿体上部;矿体转弯、膨大处及分支复合处;强冰长石绢云母硅化蚀变岩中;含细粒黄铁矿的方解石石英脉;辉银矿集中地段。

       

      Abstract: Wufeng-Wuxingshan gold deposit which occured in Mesozoic continental volcanic rock was a type of epi-hydrothermal deposit. The volcanic rock of Jingouling formation of Upper Jurassic system is the main source bed.Ore bodies are controlled by the ring and radiating fissures of the volcanic mechanism,the inner and outer contact zones of subvolcanic veins. Alkali-feldspar granite which intruded into the basal position of Jingouling formation provided the main thermal source for gold deposit Metallogenesis had mainly operated under low pressure-temperature, neutsal medium,weak oxidizing and ultra-stipergenesis conditions, Gold and silver relatively enriched in the following parts:that is①the upper part of the body;②the turning corner expanding part and the convergence of branchings of the ore vein;③strongly sericitized and adularized aItered rock;④containing fine-grained pyrite calciteqtiartz veins;⑤the concentric part of argentite.
