摘要
由海相火山岩铁矿带划分的五个成矿作用阶段,进行矿物流体包裹体的系统研究。阐述了四种类型的流体包裹体在不同成矿阶段中的分布特征。计算出不同阶段成矿溶液的热力学条件:温度、压力、氧逸度、流体成分、密度、含盐度。对该成矿带铁质来源、成矿方式、矿床成因进行了探讨。从而、初步建立了本矿带成矿模式。
Five mineralization stages can be recognized in the iron ore deposits in the Altai Area, Xinjiang.Sampes are systematically collected from the stages for inclusion study (temperature, pressure, fo_2,composition, density, salinity, etc). Based on the analysis and calculations the source of iron and thegenesis of the deposits are determined and a metallogenic model is established.
