黄梅尖地区矿床的成矿演化及地球化学特征

Metallogenic evolution and geochemical characteristics of the ore deposits in the Huangmei area

黄梅尖地区是我国重要矿藏富集区之一。从前人的资料中发现其矿床基本为中、大型规模的矿产,所以本文对该区矿床演化及其地球化化学特征认识进行一个初步总结,对该地区找矿提供理论基础。总结如下:黄梅尖地区矿体演化主要经历了早期细粒正长矿化阶段、晚期粗-中粒正长矿化阶段和基性脉状矿物矿化活动阶段,矿床源区具有深源-幔源的属性。

Huangmei apex area is one of the most important mineral accumulation areas in China.It is found that the deposits are mainly medium and large-scale minerals from the previous data.Therefore,this paper makes a preliminary summary of the evolution of the deposits and their geochemical characteristics in this area,and provides a theoretical basis for prospecting in this area.It is concluded that the ore body evolution in Huangmeijian area has mainly undergone early finegrained syenite mineralization stage,late coarse-medium-grained syenite mineralization stage and basic vein mineralization stage.The source area of the deposit has the attribute of deep-source-mantle source.
