对采自广东阳江花岗岩风化剖面的黑云母及其风化产物进行了Ｘ 射线衍射、扫描电子显微镜及能谱、高分辨透射电子显微镜等分析，并探讨了黑云母风化过程中成分的变化及矿物的转化机制。研究结果表明：阳江地区花岗岩中黑云母的风化系列为黑云母→蛭石、绿泥石→伊利石／绿泥石、高岭石；黑云母风化初期的蛭石和绿泥石是独立的矿物相，而不是通常认为的水黑云母，而混层矿物伊利石／ 绿泥石的出现则表明了以黑云母风化程度为指标的深度风化阶段；黑云母的风化是以多种模式共存的，既有单元层层间的变化，也有双层四面体的溶蚀，还包括层间及四面体变化的第三种类型。
The biotite and its weathering products collected from the weathering profile of Yangjiang granite in Guangdong Province were analyzed by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy, high-resolution transmission electron microscopy, and the changes of biotite weathering composition and mineral Conversion mechanism. The results show that the biotite series of biotite from granite in Yangjiang area are biotite → vermiculite, chlorite → illite / chlorite and kaolinite; and vermiculite and chlorite at the initial stage of biotite weathering are independent mineral phases Rather than the commonly recognized water biotite, and the advent of mixed mineral illite / chlorite indicates deep weathering with biotite weathering as an indicator. Weathering of biotite coexists in several modes, both There are layer-by-layer changes, there are double-layer tetrahedron erosion, also includes the third layer and tetrahedron changes in the third type.
