POLYGENETIC COMPOUND MINEROGENESIS IN THE LAMASU COPPER DEPOSIT,XINJIANG

Occuring near the contact between the Kuximqiek carbonate rock and the Hercynian acidic bodies,the Lamasu copper deposit is controlled by strata,magmatic rock and structure.The metallizing features have skarn,porphyry,sedimentation and hydrothermal filled styles.The metallogenic material is from strata and deep－seated magma,it has undergone many metallizing stages.So,the ore deposit is characterized by many metallo－geotectonic evolution stages,mutiple ore－controlling factors,polymaterial sources,multiple metallogenesis and polygenetic types.It is a typical polygenetic compound deposit.
