Abstract: Liushudi copper polymetallic deposit is a typical skarn copper deposit,which is located in the western Taiz river- HunJiang depression,Jiaoliao uplift belt.Based on the combination of previous data,the paper analysed the process of forming deposit from its geological features of ore deposit,geochemical characteristics and the genesis of ore deposit etc.Stable isotope composition of lead,sulfur,hydrogen and oxygen refect the ore-forming material is derived from magma,fluid inclusion data reflects the deposit is a meso-hypothermal deposit,ore-forming fluid mainly from magmatic water.The deposit had experienced three times of tectonic thermal alteration and mineralization by the influence of magmatism and tectonism.We established skarn deposit metallogenic model,which is in the contact zone between the granite porphyry and limestone.The author establish the prospecting model for the kind of deposits,which is based on the geophysical electrical features of the geological bodies with lowr resistivity and higher activation.
