摘要
本文从基础地质条件出发,全面分析了松辽盆地北部西斜坡的铀成矿条件,认为该区具有丰富的铀源和平缓东倾单斜构造、辫状河沉积体系和辫状河三角洲沉积体系,有发育良好的透水层和隔水层,补-径-排机制较完善。水文地质条件较好,具有渗入型自流水盆地特征,具备了地浸砂岩型铀矿成矿地质条件,勘探前景广阔。
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.
