The Structural Characteristics of Heyuanbei Area in the West Part of Xiangshan and its Direction of Deep Prospecting

Heyuanbei is located in the west part of Xiangshan ore-field,which is the largest volcanic type uranium ore-field in China.There are favorable uranium metallogenic conditions in the intersection of EW Heyuanbei-Fenggang graben(located in the west part of Xiangshan basin) and NE-Wutou-Xiaopi fault.The predecessors have discovered Hugang,Heyuanbei,Niutoushan,the three volcanic type uranium deposits in the area.In recent years,after the uranium resource potential evaluation and uranium survey,a new NS Kumingshan-Xiaopi fault controlling ore-belt is discovered,and a NS ore-controlling mode is proposed.Referring to the data of the geological survey,mining,uranium resource potential evaluation,uranium survey,the ore-controlling factors are described,especially the NS fault ore-controlling effect.The ore-controlling regularity are summarized,and its deep prospect direction are discussed.
