Abstract: The paragenetic association of Au-Ag tellurides in Jinjushan, Yinkengshan, Guil a izhuang and Jialu gold deposits has been studied based on the experimental resul ts in Au-Ag-Te ternary system. The space and time paragenetic association of Au-Ag tellurides and their non-paragenetic relationship have been r evealed as well. The experiments show that Au-Ag tellurides are the most import a nt minerals in this kind of gold deposits. The species and quantity of these min erals are controlled by the concentrations of Au, Ag, Te elements and their rati os in solutions of mineralizing system. The existence of petzite and hessite as low-temperature isomorphic modifications indicates that this kind of deposits h as been formed in the low temperature and low pressure environment .
