综观浙江省21个明矾石矿区和矿点,无不与火山构造有关。本文仅就该地区明矾石与火山构造的关系加以论述,以对明矾石矿的分布规律和成因机理提供一些佐证。一、明矾石矿床与火山构造的关系浙江省特别是浙东南地区,除分布少量变质岩和侵入岩体外,全省70%的大地被火山岩所覆盖。这样广布的火山岩,火山构造无疑是比较发育的。我们在研究明矾石地质资料过程中,根据火山活动产物的物质组成及形成顺序、岩相特征和原生构造等资料的综合分析,对
A comprehensive survey of 21 alum stone mining area in Zhejiang Province and ore, are all related to volcanic structures. In this paper, only the relationship between alunite and volcano structure in this area is discussed to provide some evidences for the distribution and genesis mechanism of alunite ore. First, the relationship between alum stone deposits and volcanic structures Zhejiang, especially in southeastern Zhejiang, in addition to a small amount of metamorphic rocks and intrusive rocks, the province’s 70% of the earth covered by volcanic rocks. Such a wide range of volcanic rocks, volcanic structures is undoubtedly more developed. Based on the comprehensive analysis of the volcanic activity of the material composition and sequence of formation, lithofacies characteristics and primary structure, we study the alunite geological data,
