贵州开阳白马洞铀矿是重要的蚀变型铀矿,通过对白马洞清虚洞组黑色蚀变岩及白云岩风化红粘土和寒武系牛蹄塘组黑色页岩的常量元素、微量元素和稀土元素组成的分析研究,发现铀元素含量与 Re、Se、Pb、Cu、As、Sb、Tl、Zn、Ni、Mo、Co、S 含量为正相关关系,铀含量高,则 Re、Se、Pb、Cu、As、Sb、Tl、Zn、Ni、Mo、Co、S 含量也高,其中 As、Co、Mo、Ni、Re、Tl、Zn、S 具有显著的正相关性,而且地表土壤中 Se、V、Mo 等元素的富集是铀矿找矿的主要标志之一。根据白马洞清虚洞组、寒武系牛蹄塘组黑色页岩、灯影组硅化白云岩的稀土元素配分模式分析,硒富集和铀矿化矿源层不仅是牛蹄塘组黑色页岩,可能有更深部的矿源存在。认为硒富集区是铀矿找矿远景区域;古代炼汞矿渣富集铀矿,值得开发利用和治理。
貴州開暘白馬洞鈾礦是重要的蝕變型鈾礦,通過對白馬洞清虛洞組黑色蝕變巖及白雲巖風化紅粘土和寒武繫牛蹄塘組黑色頁巖的常量元素、微量元素和稀土元素組成的分析研究,髮現鈾元素含量與 Re、Se、Pb、Cu、As、Sb、Tl、Zn、Ni、Mo、Co、S 含量為正相關關繫,鈾含量高,則 Re、Se、Pb、Cu、As、Sb、Tl、Zn、Ni、Mo、Co、S 含量也高,其中 As、Co、Mo、Ni、Re、Tl、Zn、S 具有顯著的正相關性,而且地錶土壤中 Se、V、Mo 等元素的富集是鈾礦找礦的主要標誌之一。根據白馬洞清虛洞組、寒武繫牛蹄塘組黑色頁巖、燈影組硅化白雲巖的稀土元素配分模式分析,硒富集和鈾礦化礦源層不僅是牛蹄塘組黑色頁巖,可能有更深部的礦源存在。認為硒富集區是鈾礦找礦遠景區域;古代煉汞礦渣富集鈾礦,值得開髮利用和治理。

Baimadong uranium deposit is an important alteration-type uranium deposit.On the basis of the re-search and analysis on major elements,trace elements and REE compositions of Qingxudong Formation black al-tered rock in Baimadong,weathered red clay from dolomite and Cambrian black shale,a positive correlation in concentration was found between uranium and Re,Se,Pb,Cu,As,Sb,Tl,Zn,Ni,Mo,Co,S.The content of Re,Se,Pb,Cu,As,Sb,Tl,Zn,Ni,Mo,Co,S increases with the increasing of uranium content,of which uranium and As,Co,Mo,Ni,Re,Se,Tl,Zn,S show dramatic positive correlation.Se,V,Mo con-centration in soil was considered as one of the main attributes to prospect uranium deposits.According to the analysis of REE distribution pattern among Qingxudong Formation in Baimadong,Cambrian black shale and si-licified dolomite of Dengying Formation,material source of Se concentration and uranium mineralization were not only originated from Niutitang Formation,but also possibly from deeper material source.Therefore,the Se con-centration area is probably the area that uranium deposits are located in.The ancient slag from mercury smelting concentrates uranium,which is also worth exploring and treating.
