摘　　要：鸡西盆地位于佳木斯地块南部,为一中、新生代断陷盆地。本文以黑龙江省东部的鸡西盆地为研究区,系统分析铀成矿条件。研究认为,鸡西盆地铀成矿条件良好,铀源丰富;猴石沟组、海浪组地层埋深及厚度适中,具有有利的岩性、岩相条件,发育一定规模砂体,可以作为盆地找矿目的层;盆地补-径-排体系完善,具有铀矿化显示。同时,根据区域已发现铀矿化类型,对盆地铀找矿类型进行初步预测。层间氧化带型与古河道-潜水氧化型为盆地的主要找矿类型。Jixi Basin is located in the southern part of Jiamusi Block and is a Mesozoic and Cenozoic fault basin.Taking Jixi Basin in the eastern part of Heilongjiang Province as the research area,this paper systematically analyzes the uranium metallogenic conditions.Research suggests that Jixi Basin has good uranium metallogenic conditions and abundant uranium sources;Houshigou Formation and Hailang Formation have moderate burial depth and thickness,favorable lithology and lithofacies conditions,and develop a certain scale of sand bodies,which can be used as target layers for basin exploration;the basin replenishment-runoff-drainage system is complete,showing uranium mineralization.At the same time,based on the discovered uranium mineralization types in the region,preliminary predictions are made for the uranium exploration types in the basin.The interlayer oxidation zone type and ancient channel-phreatic oxidation type are the main types of ore exploration in the basin.
