明矾石矿床是典型的浅成硫酸盐矿床,对矿床的分类也早有研究。本文以明矾石矿床的成矿物质来源为主要依据,结合矿床地质特征和稳定同位素特征,在参考了前人的分类方案后提出一种新的分类方案。在总结了前人研究的近50矿床的地质特征和硫、氢、氧稳定同位素组成特征后,将明矾石矿床分为3大类:表生型、火山-岩浆气热交代充填型和沉积型,其中又将火山-岩浆气热交代充填型分为气热型、岩浆热液型和脉(充填)型。
Alunite deposits are typical shallow sulphate deposits, and the classification of deposits has also been studied for a long time. In this paper, based on the source of metallogenic material of alunite deposit, combined with the geological characteristics and stable isotopic characteristics of the deposit, a new classification scheme is proposed after referring to the previous classification scheme. After summarizing the geologic characteristics and the stable sulfur, hydrogen and oxygen isotopic composition of nearly 50 gold deposits studied in previous studies, the alunite deposits are divided into three groups: epiphytic type, volcanic-magmatic hydrothermal substitution filling type and sedimentary type Among them, volcanic-magmatic gas-thermal interchange filling type is divided into gas-thermal type, magmatic hydrothermal type and pulse type.
