安徽省赵家岭金矿床中金的赋存特征及富集规律研究

Study on the occurrence characteristics and enrichment regularity of gold in Zhaojialing Gold Deposit,Anhui Province

安徽省赵家岭金矿位于扬子陆块北缘江南过渡带,矿床类型为构造蚀变岩型和石英脉型,矿石中金品位变化大。通过矿石特征及金的赋存状态研究,认为矿石中的金主要是以独立的金矿物自然金、银金矿形式赋存于石英、黄铁矿和脉石英的裂隙中,主要载金矿物为黄铁矿,其次为石英。

The Zhaojialing Gold Deposit in Anhui Province is located in the Jiangnan transitional zone on the northern margin of the Yangtze block.The deposit is characterized by structural altered rock type and quartz vein types,with significant variation in gold grade within the ore.Based on the study of the ore characteristics and the occurrence of gold,it was believed that gold in the ore predominantly occurs in the fractures of quartz,pyrite,and vein quartz as independent gold minerals,namely natural gold,and silver-gold ores.Pyrite is identified as the primary gold-bearing mineral,followed by quartz.
