鲁西柳家电气石矿矿物学特征及成矿机理探讨

Study on Mineralogical Characteristics and Ore-forming Mechanism of Tourmalinite in Liujia of West Shandong

鲁西柳家电气石矿矿石呈黑色或绿黑色 ,为柱状、纤维状集合体。电子探针和X衍射结果表明 ,该电气石矿主要矿物成分为铁镁电气石 ,属镁电气石和铁电气石的过渡类型。其成矿系统分为成矿热流体体系和控矿环境两部分 ,其成因类型与脉石英相似。

Tourmalinite in Liujia of west Shandong has black or dark-green colour pillar-shaped of fiber-like aggregate. According to electronic microprobe and X-ray diffraction analysis results, it is iron-magnesium tourmalinite which belongs to transitional type between dravite and iron tourmalinite. Its mineralization system is composed of two parts as: hydrothermal system and mineralization-controll environment. The genesis is similiar to quartz-vein.
