早前寒武纪热液矿床成矿后岩脉的鉴别

On Discremination of Postore Dykes in Early Precambrian Hydrothermal Deposits

从矿体与岩脉的接触关系,和早前寒武纪热液矿床地质基本特点出发,举出鉴别早前寒武纪热液矿床成矿后岩脉的一系列实例。

Proceeded from the relation of an orebody to the dyke come in contact with and from geologicalcharacteristics of Early Precambrian hydrothermal deposits,a discremination of postore dykes in suchtype deposits was made and practical examples were given.
