摘要
Lawu copper zinc ore deposit in Damxung County Tibet laid in the Jiangrang-Boshulaling polymetallic metallogenic subzone of the Gandise-Nyainqentanglha metallogenic belt.In lights of geological properties,stable isotope,rare earth elements,trace element geochemistry,the authors analyzed ore body V.It was concluded that the genesis was magmatic skarn type,the differentiation of deep magma during its upward invasion was the genetic mechanism,the melted lava dominated by K,Na silicates floated on the upper part,while the melted lava dominated by Ca,Mg and Fe(skarn magma) settled on the lower part,forming ore-bearing skam magma,and then magmatic skarn ore deposits.
