| Abstract: | 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. |
