摘要
(?)南的共生与(?)生金矿庆中的金,大部分为次显微金和(?)显微金.(?)中的黄铁矿和毒砂是金的主要载(?)矿物.金主要以机械混合物或微包体形式赋存,主要形成于硫(?)化物矿化(?)或晚期.矿石合金量的高低与载金矿物的晶形,(?)度,生成期及碎裂程度等有关.(?)黄铁矿、毒砂是金矿床的主要标型矿物.As是标型指示元素.
The gold-bearing deposits can be divided into coexisting and associated gold deposits, in which most of the gold are sub-microscopic and / or microscopic one. Pyrite and arsenopyrite in the deposits are major host minerals for gold. The gold mainly forms in sulfide (arsenide) mineralizing period, and occurs mainly in the forms of mechanic mixture of micro inclusion. The gold concentration in ore is related to crystal shape, granular, forming periods and cataclastic degree of the host minerals for gold. Pyrite and arsonpyrite are the major typomorphic minerals of gold deposit, and As is a typomorphic indicator element.
