【摘要】 描述了层状电气石岩的物理特征、岩性组合特征,分析了其化学成分,作了理论研究,确定了该层状电气石岩为火山喷气—沉积变质成因,形成于海底火山喷气—沉积构造环境中,其原岩是一套富硼镁的泥铁质—硅质岩石。它的发现对在该地区找矿具有重要指导意义。更多还原

【Abstract】 The physical properties and lithological association characteristics of the bedded tourmaline are described, theoretically, making further study. Thus, it is determined that the bedded tourmaline belongs to volcanic exhalation-diagenic metamorphic origin, forming in the submarine volcanic exhalation-sedimentary tectonic setting, its primary rock is a set of the rich B-Mg argillaceous iron-silica rock. Its discovery has an important directive function for ore-search in this area.更多还原
