The author found that the big piece-size muscovites of China are the normal muscovites; the small-size muscovites in the metamorphic rock area are mainly phengite. The Indian muscovites studied both big and small piece-size of muscovite, are normal muscovites. The surface activity of Indian muscovite substrate is higher than China ones. Acid is easy to erode paralleling to the direction of the muscovite substrate face. Although acid treating does not destroy the muscovite structure, the thermal stability of muscovite has be decreased.
研究发现我国白云母主要产地的大片白云母均为普通白云母,变质岩地区的碎白云母以多硅白云母为主;本文研究的印度的大片白云母、碎白云母均为普通白云母;印度白云母基片的表面活性高于我国白云母;酸处理容易沿平行于白云母基面的方向侵蚀,虽未使白云母晶体结构产生破坏,但造成了白云母热稳定性降低。
