The high - pressure metamorphic rocks in northeastern jiangxi province include such types of rocks as jadeite - bearing aegirine - augite albite amphibole schist , jadeite - bearing aegirine - augite quartz albitite , aegirine - augite - bearing amphibole quartz albitite , aegirine - augite - bearing albite amphibole schist , winchite quartz albitite , and magnesio - riebeckite quartz albitite 摘要赣东北高压变质岩包括含硬玉霓辉石钠长角闪片岩、含硬玉霓辉石石英纳长石岩、含霓辉石角长闪石英钠长石岩、含霓辉石钠长角闪片岩、蓝透闪石石英钠长石岩、镁钠闪石石英钠长石岩等岩石类型。
The texture can be systematically classified as the six types : the felt - like texture , the micro - fibrous cryptocrystalline texture , the micro - fibrous texture , the micro - leaf - like cryptocrystalline texture , the micro - leaf - like texture and the radiated fibrous texture 通过对青海软玉显微结构的观察与研究，按其主要矿物透闪石组分的表现形式，较为系统地划分青海软玉的主要结构类型为：毛毡状结构、显微纤维隐晶质结构、显微纤维结构、显微叶片状隐晶质结构、显微叶片状结构以及放射状纤维结构。
The fluids upwelled to seafloor along fault thus ore - forming metals accumulated . 2 . this paper indicated the definition the hydrothermal sedimentary rocks . the definition is a group of especial sedimentary rocks forming at the temperature ranging from 70 ? to 350 ? ( or more high ) through sedimentation and synsedimentary metasomatism in the seafloor 区内的热水沉积岩主要有硅质岩、钠钾长石岩、重晶石岩、透闪石岩、碳酸盐岩、绿泥石岩和铁白云石斑点千枚岩，它们往往与热水沉积矿体紧密伴生。
The main element analysis of whole rocks , the ree analysis and the trace element analysis have been done for the granitoid samples in this area . the chemical composition analysis has been done for the amphiboie and biotite minerals . the epma and x - ray powdered crystal diffraction have been done for k - feldspar , plagioclase , amphiboie , biotite , quartz , magnetite , titanite 对本区花岗岩类样品进行了全岩主量元素、稀土元素及微量元素分析，对角闪石和黑云母单矿物进行了化学成分分析，对钾长石、斜长石、角闪石、黑云母、及石英、磁铁矿、磷灰石和榍石进行了电子探针和x射线粉晶衍射分析。
