A STUDY OF GEOLOGY,GENESIS AND ORE CONTROL FACTORS OF THE KAXIUTATA SKARN TYPE IRON,GOLD DEPOSIT,ALXAYOUQI COUNTY,WESTERN INNER MONGOLIA

AN Guo-bao

Abstract

The Kaxiutata Fe-Au deposit is a hydrothermally overprinted skarn deposit.Specific lithology,magmatic rock and structure are the basic condition for formation of the deposit.Contacts between the gabbro and quartz diorite control occurrence of the deposit;contacts of the intrusive rocks with the country rock the distribution of the Fe,Ag ore bodies;interformation fractural zone and tectonic fractural zone morphology of the ore bodies.Iron mineralization occurs in skarn at contacts of the intermediate-basic intrusive rocks and Au ore bodies in rich Fe ore bodies and skarn near them.The Au-ore and the Fe-ore are the different-staged products of one geological process.The iron,gold ore deposit could be formed in middle Hercynian period.
