Nanoscopic feldspar islands on K-feldspar microcline (001)

Physical Chemistry Chemical Physics
High-resolution atomic force microscopy on microcline (001) reveals nanoscopic islands, which have the same atomic structure as the terrace and are stable in contact with water. The islands were identified as an intrinsic feature of the surface.

ELECTRON-MICROSCOPIC INVESTIGATION OF MICROCLINE-ORTHOCLASE PERTHITE

The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1973
Microscopic structures which are considered to represent a transitional state from orthoclase to microcline were observed in microcline-orthoclase perthite by means of the optical and electron microscopes. Due to the cross-hatching of the orthoclase, strain existing around perthitic albite in the orthoclase is stretched in the direction parallel or ...
