摘要
笔者在分析前人成果的基础上,通过综合湘西及黔东地区下寒武统黑色岩系底部"多元素富集层"的地质特征,进行了区内沉积成矿带的初步划分,并对"多元素富集层"的成因作初步的探讨。主要取得以下认识:(1)把湘黔下寒武统黑色岩系中的"多元素富集层"广义化,在研究区内划分为钼镍硫化物层和含钒碳质页岩层两种类型;(2)在研究区内多元素富集分带特征具有中部及南部钒富集、北部钼镍富集、东部金银富集和南部重晶石矿富集的明显特征;(3)初步把区内分为钼镍-钒矿成矿带和钒-银-重晶石矿成矿带2个成矿带;(4)其成因与深大断裂及基性超基性岩浆活动关系密切;(5)其海底热水(喷流)沉积成因在不同的区域表现为不同的形式。
on the basis of the former study, by summarized the geologic characters of multi - element concentration stratum of black rock series, lower Cambrian series in Hunan and Guizhou, it did the preliminary division for the regional sedimentary metallogenic belt and discussed the causation of multi - element concentration stratum. The achieved cognitions are follows： （ 1 ） broaden the multi - element concentration stratum in Hunan and Guizhou, divided into Mo, Ni sulphide and vanadium bearing carbonaceous shale stratum; （2） the characters of the multi - element concentration belt include： vanadium concentrated in the south, molybdenum and nickel concentrated in the north, gold and silver concentrated, barite deposit concentrated in the east; （3） divided into two metallogenic belt： Mo, Ni and V metallogenic belt and V, Ag and barite metallogenic belt; （4） the causation had deep relation with the deep and big rupture and basic - ultrabasic magmatic activity; （5） the causation of submarine thermal water sediment represented different formations in different areas.
