Abstract
The B K-edge spectra of a wide variety of minerals have been measured using the technique of parallel electron energy-loss spectroscope (PEELS) conducted in a scanning transmission electron microscope (STEM) from sample areas of nanometer dimensions. The B K edges of the minerals exhibit electron energy-loss near-edge structure (ELNES) characteristic of B coordination. The origins of the B K ELNES are discussed in terms of both molecular orbital (MO) and multiple scattering (MS) theory. The paper also presents the B K-edge spectra of selected non-minerals and shows how differences in edge shapes and energy onsets allow these nonminerals to be readily distinguished from borates and borosilicates. -from Authors
