THE EXPLORATION RULES OF DUCTILE SHEAR ZONE GOLD DEPOSITS OF THE PRECAMBRIAN SYSTEM IN CHINA

摘要

Ductile shear zone gold deposits occurred in the Precambrian system have enormous prospecting potentiality in China. The production scale of gold mining from Precambrian System is large and its known gold reserves occupy a high fraction of the gold in China. Therefore a systematic presentation was made with the aim of generilizing experiences, elevating and guiding the coming gold prospecting. The principal problems concerned in this paper were the auriferrous bearing rock system and the gold deposit types in ductile shear zone, the enrichment rules and the mineralization of the ductile shear zone gold deposit, etc.
