Abstract:

Based mainly on the macroscopic geological features,combined with ore-forming processes and mechanisms,the gold deposits in the western Sichuan may be divided into nine types.The superior grades of nine types of gold deposits can be determined from the studies of the distribution of gold deposit type in the dominant strata,grades and tonnage models of various types.It is suggested that the underground hydrothermal type gold deposits hosted in slightly metamorphic rock series and ophiolitic mélange are the most important ones in which super-large gold deposits would be found.

Key words: Gold deposit classification, dominant type, western Sichuan
