| Abstract: | Based on the geological advantage,this paper completely analyses metallogenic condition of west slope of the north of Songliao Basin.The paper suggested that the region has abundant uranium source and favorable flat east declination uncial structure.There are permeable stratum and water division layer in braid river sedimentary system and braid delta sedimentary system,which the recharge-runoff-discharge mechanism is relative complete.This area being advantageous to Hydrogeologic and characterized by the permeable artesian basin,which satisfies the essential metallogenic geologic requirements for forming leaching sandstone uranium deposit and shows a good exploration prospect. |
