低温高压微地质体中微米纳米级矿物相研究——以大冶葡萄石中绿纤石和多硅白云母为例

Nanometre micron Scale Mineral Phases in the Micro geological Body Formed at High Pressure and Low Temperature: In Case of Phengite and Pumpellyite in Prehnite from Daye,Hubei Province

低温高压地质体因与地壳碰撞、俯冲等构造活动密切相关，长期以来一直是国内外地学界关注的研究对象。但由于受研究手段、分辨能力所限，对于呈微米纳米级微粒形式存在于低温高压微地质体（即矿物）中的成分、物相及其成因等问题的研究，至今仍是地学研究中的薄弱环节。随...

Phengite and pumpellyite on the nanometre micron scale in the micro geological body(prehnite) from Daye, Hubei province, have been researched by power X ray diffraction (PXRD), electron microprobe(EMP), scanning electron microscope(SEM) and transmission electron microscope(TEM). The result had offered a sufficient evidence that the prehnite had experienced a high pressure low temperature metamorphism. The research method and idea used in this paper had some guide significance for other researches on micro geological bodies.
