The Ore Minerals Under the Microscope: An Optical Guide, Second Edition, is a very detailed color atlas for ore/opaque minerals (ore microscopy), with a main emphasis on name and synonyms, short descriptions, mineral groups, chemical compositions, information on major formation environments, optical data, reflection color/shade comparison with four common/standard minerals of a similar color or grey shade, and up to five high-quality photos for each mineral Book Edition: 2nd Edition. Study of Ore Minerals in Reflected Light. The Ore Microscope. The basic instrument for petrographic examination of „ore‟ minerals or „opaque‟ minerals is the ore microscope, which is similar to a conventional petrographic microscope in the system of lenses, . Box 3 Determining mineral chemistry. Another way of mapping minerals is by back-scattered electron (BSE) imaging. This is an image of the electrons that are scattered or bounced back by atoms bombarded by the electron beam. The number of electrons back-scattered is proportional to the mean atomic mass of the spot under the beam.

Minerals under the Microscope The microscope is a fundamental tool that is used in many branches of the Earth Sciences. When a slice of a rock is mounted on a glass slide and thinned, it is possible to see through many minerals and observe their optical properties/5. Box 3 Determining mineral chemistry. Another way of mapping minerals is by back-scattered electron (BSE) imaging. This is an image of the electrons that are scattered or bounced back by atoms bombarded by the electron beam. The number of electrons back-scattered is proportional to the mean atomic mass of the spot under the beam. In the first step of a microchemical analysis of an ore mineral, a suitable solvent dissolves a tiny grain of mineral scarcely larger than the point of a pin. The single drop of solution is then subjected to chemical manipulations, and the results are observed under the. lens of a microscope. ISBN (PDF). by M.M. ..
