Abstract:

Mulutang gold deposit is located in the holding location of Ailaoshan and Tengtiaojiang fault,the fracture is general development in this area,which provides a good channel and place for enrichment of gold.The magmatic activity is strong in this area,which has the characteristics of multi-phase and multi-stage acitivities,and undergo three major magmatic activity periods,inclulding Lvliang,Variscan and Indosinian period,also provides sufficient material source and thermal power for mineralization.We think that pyrite,arsenopyrite and silicification alteration are related to gold mineralization by summarizing geological characteristics and wall rock alteration of the deposit,we infer that genesis is structure altered rock type and secondary oxidized.In addition,we delineat favorable abnormal area by geophysical and geochemical explorating,and suggest that this area has better prospecting.

Key words: Geological characteristics, Genesis, Magmatic activity, Malutang gold mine, Yunnan Province
