Huangbaigou ore deposit is a granitic pegmatite uranium deposit newly discovered in the pe-riphery of Huichizi pluton in West Henan province.The Previous prospecting is successful.This paper deals with characteristics of the uranium ore and chemical composition of the crystalline uranium mineral,genesis of the pegmatite and the prospecting marks and direction.The ore is hosted in biotite pegmatite developed with graphic pegmatitic texture and characterized by large grain size,high content of biotite,i.e.high Si and K and Al supersaturation.Crystalline uranium mineral is the main ore mineral occurring as micro-veinlets at joints or at contact surfaces of the boundaries and euhedral crystalline uranium mineral grains in biotite pegmatite.Uranium is main composition of the crystalline uranium mineral,then Th and Pb.It is relatively rich in rare element Y and the rare element is closely related to uranium.Further pros-pecting should be focused on biotite pegmatite within scope of 0-200 m of the outer contact zone of Huichi-zi pluton.
