It is considered that Jiamante gold deposit of Xinjiang is a meso-epithermal quartz-vein type gold deposit. The mineral composition is relatively complex

and most of them are metal sulfides

which have the low formation temperature. This paper has done some analysis on the firstly discovered copper sulfides including chalcocite which are formed in main mineralization stage of quartz-sulfide: Through microscopic identification

it is known that the copper sulfide series are associated with other metal sulfides and gold

and replaced by metallic oxide formed by supergene mineralization; Through Electron probe microanalysis

it is found that these copper sulfids have high content of gold and silver

especially the silver

meanwhile

the crystal chemical formulas of these minerals have been calculated

thus

to some extent

the trace elements' geochemical behaviors can be revealed; Lastly

through the comparison with the copper sulfide series of Zijinshan gold-copper deposit

the foundation can be laid for further ascertaining the type of Jiamante gold deposit.
