| Abstract: | The Wuyankeng orebodies of molybdenum deposited in Yongtai County the metallogenic parental rock mass： Which is the border facies what has the moderate and thick grain size of granite in the Yanshan terminal stage that comprises biotite-granite, The alteration zone was bending band around the volcanic rocks and granite ore body in contact with the distribution structure, The ore-bearing rock is along the wall-rock alteration of inside and outside the contact zone development. The wall-rock alteration developed around the Volcanic rocks and granite-forming of the ore-bearing rock mass, The main ore reserve structures are the tumor- like granite rock in contact with structure, viz. the convex rocky structure （The opposite concave rocky structure, The structure of the reservoir rocky Ore adverse）; As well as regionally fractures structure to the N-W side of the sub-structural faulted structure. The mineral deposit belongs to the post-magmatie hydrothermal filling type. |
