本文以原生晕垂向分带理论为指导,运用多元统计方法对棉花坑铀矿床9号脉垂向上原生晕特征进行研究,查明成矿及伴生元素组合特征,建立元素垂向分带序列。结果表明,U、W、HREE、Pb为棉花坑铀矿床主要成矿元素,矿头晕以 Cu、Zn、Ni 为主,矿尾晕以 Sr、Ba、Bi 为主。通过对棉花坑铀矿床原生晕特征的综合分析,指出了该矿床480 m 以下仍具有很大找矿潜力,并总结了热液型铀矿深部成矿预测标志。
本文以原生暈垂嚮分帶理論為指導,運用多元統計方法對棉花坑鈾礦床9號脈垂嚮上原生暈特徵進行研究,查明成礦及伴生元素組閤特徵,建立元素垂嚮分帶序列。結果錶明,U、W、HREE、Pb為棉花坑鈾礦床主要成礦元素,礦頭暈以 Cu、Zn、Ni 為主,礦尾暈以 Sr、Ba、Bi 為主。通過對棉花坑鈾礦床原生暈特徵的綜閤分析,指齣瞭該礦床480 m 以下仍具有很大找礦潛力,併總結瞭熱液型鈾礦深部成礦預測標誌。

According to the theory of vertical zoning of primary halos, multivariate statistical method was used to study the vertical zoning characteristics of primary halo over orebody No.9 in Mianhuakeng uranium deposit.The characteristics of ore forming and associating elements combination was found, and the vertical zoning sequence of indicating elements was established.Primary halo investigation revels that U,W,HREE and Pb were primary ore forming elements in Mianhuakeng uranium deposit,and the front halo was composed of Cu,Zn and Ni,whereas the rear halo composed of Sr,Ba and Bi.Based on the comprehensive analysis of the characteristics of primary halo in Mianhuakeng uranium deposit, predicting indications was summarized for deep exploration.It was pointed out that space below 480m level was potential for further prospecting.
