丹寨汞矿是产于碳酸盐岩地层中以汞为主伴生金的浅成低温层控矿床。本文对该矿床矿石及围岩中的卤素元素分布特征进行了一定的研究。研究结果表明 :1矿区内 Br、I的富集程度远比 F、Cl高 ,从远矿围岩→近矿围岩→汞矿石 Br、I含量呈增加趋势 ,金矿石中 Br、I含量比近矿及远矿围岩含量低 ,且 I的富集系数小于 1;2 F在金矿化岩石及近矿围岩中含量较高 ;3Cl的变化规律不甚明显 ,且富集系统均小于 1;4垂向上汞矿石中 Br、I在矿体上部富集 ,近矿围岩中Br、I主要富集在中部 6 53～ 6 90 m中段区间 ;5Br、I可作为寻找汞矿的指示元素
Danzhai mercury deposit is produced in carbonate rock strata with mercury as the main accompanying epithermal deposit. In this paper, the distribution characteristics of the halogen elements in the ore and the surrounding rock of the deposit have been studied. The results show that the concentration of Br and I in the ore district is much higher than that of F and Cl, and the content of Br and I in the ore from the ore surrounding rock → the ore surrounding rock → the content of Br and I in the gold ore increases The content of surrounding rock in near mine and distant mine is low, and the enrichment coefficient of I is less than 1; the content of 2 F is high in gold mineralized rock and near mine rock; the variation law of 3Cl is not obvious and the enrichment system is less than 1; 4 Br and I in the vertical mercury ore are enriched in the upper part of the ore body; Br and I in the near ore rock are mainly concentrated in the middle part of 536 ~ 90 m in the middle part; 5Br and I can be used as an indicator for finding mercury deposits element
