一个干旱地区毛矾石矿氧化带的矿物组合

MINERAL ASSEMBLAGES IN OXIDATION ZONE OF KATHARITE DEPOSIT IN AN ARID REGION

在陆相古火山角砾岩筒中由火山热液蚀变产生的含黄铁矿次生石英岩中的硫化物,在特别干旱的条件下生成了以毛矾石及黄钾铁钒为主的13种钒类矿物组成的硫化矿床氧化带,并在其中聚集了毛矾石矿体。毛钒石矿是由反复进行的氧化-渗透淋滤作用而富集形成的。

The oxidation zone of sulphide deposit,composed of thirteen vanadium minerals,mainly of rare katyarite and kolosorukite,was formed in an arid condition from the sulphide in the secondary quartzite bearing pyrite. The sulphide was formed in a paleovolcanic breccia cylinder by means of volcanic hydrothermal alteration. The katharite ores were concentrated in the oxidation zone from repeated oxidation, permeability and leaching.
