The Bi mineralization is described in quartz-sulfde veins of the Nazarovskoe gold polymetallic deposit (Western Transbaikalia), which is localized within the Eravnino volcano-tectonic structure and is confned to the Nazarovskoe fault zone and the contact with a granodiorite pluton intruding volcanosedimentary rocks. The Bi minerals include Ag-Bi, Cu-Bi, Pb-Bi, and Ag-Pb-Bi sulfosalts, Bi sulfotellurides, aikinite, and native bismuth in assemblage with chalcopyrite and galena. Most Bi minerals are described for the frst time both for the Nazarovskoe deposit and the entire Ozerninsky ore cluster.

The versatility of natural clay and their ability to adsorb a variety of environmental contaminants present in the water effluents has attracted esthetic concern among environmentalist. These practical applications rely primarily on the diversity of natural clay structure to retain harmful and undesirable substances from the immediate environment. The adsorptive capability of natural clays is related to the fundamental units of the clay-sized crystalline minerals which present in different combinations.

A two-part system to describe the mineralogy of the mineral part of coal samples has been developed. One part consists of a procedure which uses normative minerals to match the real ones determined by X-ray diffraction, and whose detailed chemistry sum up to the observed oxides measured by X-ray fluorescence. The other part uses linear programming, with more realistic mineral compositions, to achieve a realistic description of the minerals present in the coals. Despite differences, these two methods achieve a similar results in the end and complement each other.
