摘要
湘西北地区下寒武统底部黑色页岩中的镍钼多金属矿床，受区域性断裂严格控制，矿床良海底补给与化学沉积两套成矿系统，有较典型的喷气岩一硅质岩和筒状矿体，以及特殊的Ｎｉ、Ｍｏ、Ｖ、Ｐ，Ｐｄ、Ｐｔ、Ｂａ元素组合和高Ｂａ值，反映出这类矿床的成因属性，并非陆源搬运沉积，而是海底喷气沉积矿床。
Ni,Mo-polymetallic deposit in black shale of Lower Cambrian System is strictly controlled by regional faults. Two sets of mineralization exist:1)ore materials recharged by sea bottom and 2)that caused by chemical precipitation. In the deposit there are typical exhalite-siliceous rocks and pipe-Like ore bodies,spe- cial association of Ni,Mo,V,P,Pd, Pt and higher content of Ba,which rellect the origin of the deposit,It dees not belong to the terrigenous sedirnentation but the one of the sea exhalaition.
