| 摘 要： | 我国南部早寒武世黑色岩系中，蕴藏丰富的金属和非金属矿产。而位于扬子地台东南缘的钒矿床尤其令人瞩目。本文以湘西为例，剖析该类钒矿地质特征和成矿规律。矿床产于下寒武统黑色岩系底产的碳系页岩、硅岩及黑色页岩组合。矿层呈层状、似层状，产权稳定，埋藏浅，储量大。矿石主要由水云母（伊利石）和石英组成，含有机质及藻类化石。成矿受地层、岩性、古构造和古地理条件控制。矿床具有微生物成矿与海底热水沉积双重特征，成因应属生物地球化学积积矿床范畴。

| Abstract: | In South China,the Early Cambrian black rock series is rich in metallic and nonmetallic mineral ersources.And the V deposit in SE margin of the Yangzi platform is especially attractive. Taking the V deposit in west Hunan as an example,we analyse the geological characteristics and metallogenetic law of it.The ore deposit is occurred in the assemblage of carbonaceous shale,sillicalite and black shale of the bottom of Lower Cambrian black rock series.The ore beds are stratified,stratoid,with stable,shallow occurrence and large reserves.And the ore contains hydromica(illite),quartz,organic material and algal fossil.The metallogenesis ia controlled by strata,lithology,palaeostructure and palaeoggraphic conditions,characterized by microbial and seabed hydrothermal activities.The genesis of the ore deposit must belong to the biogeochemical sedimentation type. |
