摘要在黄沟铀矿床勘探过程中发现赤铁矿化与铀矿化共生.通过手标本观察，结合岩矿鉴定并采用扫描电镜化学分析，认为赤铁矿化为成矿期蚀变，分为砖红色和棕褐色两种类型.砖红色赤铁矿化蚀变岩中黑云母未完全蚀变成绿泥石，对于铀矿有一定的指示作用；而棕褐色赤铁矿化蚀变岩中黑云母几乎全部被绿泥石交代，可作为本区铀矿找矿重要标志.

Abstract：The paragenesis of hematitization and uranium mineralization is discovered in the exploration of Huanggou uranium deposit in Liaoning Province. Based on the hand specimen observation and SEM chemical analysis, it is believed that the hematitization belongs to metallogenic alteration, which is presented in brick red and dark brown colors. In the brick red-colored hematitization, biotite rock is incompletely altered into chlorite and would provide certain indication for uranium deposit. While in the dark brown alteration, almost all the biotite is replaced with chlorite, which can be taken as a significant prospecting indicator.

Key words： hematitization uranium mineralization prospecting indicator Huanggou uranium deposit Liaoning Province
