Abstract

Mawu gold deposit is a medium-sized fine disseminated gold deposit discovered in recent years,located in western segment of Western Qinling Li-Min metallogenic belt.The orebody is controlled by NWW trending faults,with the wall rocks consisting of phyllite and limestone in Hejiadian Group of Middle Devonian.The shear dynamic system is the leading factor of metallogenic structure in Mawu gold deposit,the secondary ductile-brittle shear structure of the deposit controlled the occurrence of gold mineralization alteration zones and the orebody.The ductile shear deformation and metamorphism characteristics of the strata and rocks are very typical.The source bed,fluid nature and origin,orebody morphology and ore types were reflected the characteristics of ductile shear zone type gold deposit.Under the combined effect of trinity“gold-rich strata,shear zone,magmatic activity”,formed low temperature micro-disseminated-type deposits.The orebody was eroded to the middle position and downwards,there was still some scale extends to the deep.
