The Sujia iron polymetallic deposit is located in the Zhangguangcai Range metallogenic belt of Heilongjiang Province��controlled by the Yizuomao alkali feldspar granite and granite porphyry�� The orebodies were hosted in the contact zone of granite-porphyry and marble��and in the interlayer fracture zone��being mainly as skarn Fe-Zn orebodies in type�� The metallic minerals of orebodies are composed mainly of magnetite and sphalerite�� The alteration of wall rocks mainly were skarnized��petrified��hornfels��carbonation and chloritization in type��in which the skarnized was closely related to mineralization��being as the main prospecting criteria�� The characteristics of geochemistry indicate that the metallogenic material mainly came from the evolution of crust-source magma and upper carbonate rocks�� The hydrothermal mineralized bodies and orebodies occurred in the skarn rock which formed by the hydrothermal metasomatism with carbonate layer�� Combined with the regional geological background��we determined that the Sujia iron polymetallic deposit was skarn deposit in type��
