摘　　要：湘西北镍钼多金属矿床富集了多种元素，形成一个以Ｎｉ、Ｍｏ、Ｃｕ、Ｚｎ、Ｐｄ、Ｐｔ、Ａｓ、Ｓｅ、Ｂａ、Ｖ、Ｐ为主的特殊元素组合；微量元素Ａｓ、Ｓｅ、Ｂａ等成１０１～１０３倍富集。它们的地球化学特征表明，这类矿床属海底喷气沉积矿床。这组特殊元素的来源和富集。A variety of elements,mainly Ni,Mo,Cu,Zn,Pd,Pt,Se,Ba,V and P,form a special association and are enriched in Ni-Mo polymetallic deposits in Northwestern Hunan.Trace elements such as As,Se and Ba in these deposits are tens or hundreds or even thousands times as abundant as those in the earth crust.Their geochemistry shows that the souece and enrichment of these elements are related to seafloor exhalation and this kind of deposit should be of the seafloor exhalation-sedimentary type.
