| Molybdenum is an important strategic resources, widely used in high-tech fields. Located in the Zhengxiangbaiqi-Duolun polymetallic (Au-Pb-Zn) ,northern margin of the North China platform ,The newly discovered Shazigou Mo deposit have a low research. Through the data collection, analysis methods of field investigation, thin section identification,trace elements, compositions of fluid inclusions and stable isotope, study geological characteristics and discuss the genesis of Shazigou Mo deposit.the following achievement have been obtained:1,The deposit occurs in metamorphic rocks of Baiyunebo group. It is composed of four mineralized zones, they are typically between 60 and 70 degree,almost near the level of relief wavy spread,and about 500 meters long,700 meters thick,Ore bodies are like thick layer, The ore typically shows granular structure, disseminated structures. Molybdenite shows thin vein-like, star-shaped points .2,Process was divided into hydrothermal ore mineralization period supergene stage, Hydrothermal mineralization is further divided into quartz - wolframite, quartz - molybdenite - pyrite, quartz - sulfide ore-forming three stage, quartz - molybdenite - pyrite mineralization stage is the main stage.3,δ34S=6.7‰~7.1‰, the average value of 34S in pyrite is 6.9‰c the sulfur came mainly from the deep magma. Composition of fluid inclusions is type of silicate melt and metal component,Infer magmatic water is the main ore-forming fluid.The genetic type of siderite deposit belongs to quartz-vein Mo deposit .The study can not only guide the deep exploration and external prospecting, but also conducive to the northern margin of North China block-rich polymetallic metallogenic belt theory.
