摘要
珊瑚钨-锡(银)矿床具典型的垂直逆向分带特征,自浅部向深部成矿温度逐渐降低,矿物组合中挥发组分减少。本文利用电子探针分析,研究了矿床中前人没有发现的三种含银硫盐矿物及其物理性质和化学成分特征。结果表明,钨-锡矿脉中含银硫盐的产出具有明显的规律:水平剖面上富集于脉中;垂直方向上,富集于矿脉的中、下部。
The Shanhu W-Sn(Ag) deposit has typical characters of vertical reversed zonation,the ore-forming temperatures gradually depress from the upside to the bottom,and the contents of volatile components reduce in the mineral combinations.On the basis of the conventional microscope observation and electronic microprobe analyses,this work studied the physical properties and chemical compositions of silver-bearing sulphosalts,and found three new silver-bearing sulphosalt minerals in the deposit.The study results showed that silver-bearing sulphosalts present a visible pattern in the W-Sn veins: horizontally,silver-bearing sulphosalts enrich in the middle of the veins;vertically,silver-bearing sulphosalts enrich in the middle and bottom of the veins.
