Metallogenic model and prospecting model in Xiaojiayingzi molybdenum polymetallic deposit of Liaoning

Xiaojiayingzi molybdenum polymetallic deposit located in Kalalazuoqi,is a large-scale porphyry-skarn type molybdenum deposit in western Liaoning.The deposit formation has a definite relationship with the carbonate of Wumishan Formation in Jixian System,porphyraceous fine-grained diorite intrusived in Yanshanian,NNE and NWW Kazuo-Zhongsanjiazi subordination faults.According to the study of geological background for mineralization,geological characteristics and genetic type of mineral deposit,the authors establish the metallogenic model of Xiaojiayingzi molybdenum deposit.On the basis of metallogenic model,the relationship among geophysical and geochemical exploration anomaly with rock mass,contact zone and orebodies are studied,and the authors have established the geological,geophysical prospecting and geochemical prospecting models.
