Electron microscopy biotite

Figure 3. SEM/EDX images of (a) ferric hydroxide coating on a feldspar grain, (b) EDX spectra of ferric hydroxide on a quartz grain, (c) chemical weathering of biotite platelets, and (d) etch pits on a plagioclase mineral grain. All grains were taken from surface sediments of Lake Cristallina, Switzerland. Photographs are courtesy of Professor Rudolf Giovanoli, Laboratory of Electron Microscopy, University of Bern.

The new types of bands were found by high resolution electron microscopy (HREM) in biopyribols, which contain construction elements common also with pyroxenes, mica (biotite) and amphibols. There are bands, formed by 2, 3 and sometimes by even more than 10 pyroxene chains, which gradually become layers.
