Abstract

Abstract:

Jiagantan gold deposit is a super-large gold deposit newly discovered in recent years，which is located at the south of Xiahe-Hezuo fault zone of West Qinling.The occurrence state of gold were studied by microscopic test technology，the primary ore samples were observed in detail by high power optical microscope and scanning electron microscope（SEM）.It is concluded that the metallic minerals in primary disseminated ore are mainly arsenic pyrite and arsenopyrite，and the natural gold inclusions couldn’t be found in observing the BSE images.So the conclusion is that the microscopric invisible gold is occurrence state of gold in gold bearing minerals.

Key words: occurrence of gold, microscopric invisible gold, Jiagantan gold deposit, Gansu Province
