| Abstract: | Damoqujia gold deposit is an alteration type gold deposit where the gold occurs in the crash belt. The main ore is beresitization, beresitization cataclasite, polymetallic ore and a little amount of auriferous quartz vein. The deposit experienced two metallogenic period, hydrothermal metallogeny and supergenic metaUogeny, and the metallogenic stage can be classified as 5 stages, which is embodied as pyrite-qnartz, quartz-pyrite, polymetallic sulfide and carbonate. Pyrite is the main gold loading mineral, and the gold mineral is natural gold or electrum. The occurrence states of gold are expressed as gold inclusion, interstitial gold and fracture gold. The interstitial gold and fracture gold makes up 79% of them, and the grade of gold mineral is mainly medium-grained and fine, which makes up 69 % of the gold mineral. |
