MINERALOGY OF HOST ROCKS OF THE OSINOVSKOE GOLD-QUARTZ DEPOSIT (CENTRAL URALS) [PDF]
The paper describes the mineralogy of mica shales of the Osinovskoe gold deposit in the Central Urals. Our studies unraveled the role of dynamometamorphism in the transformation of primary rocks and allowed the characterization of their metasomatic ...

New data on the mineralogy of the gold-sulfide ore type of the Karalveem deposit, Chukotka
In this paper, we present the results of a mineralogical study of the ores of the Karalveem deposit in the northeast of Russia (Central and Ruslovy areas). Gold mineralization is characterized by two types of ores: gold-quartz-arsenopyrite (quartz veins

Metal sulphides are the most important group of ore minerals. As shown in this brief introduction, much is known about their compositions, crystal structures, phase relations and paragenesis. Much less is known about their surface chemistry and, in particular, about their biogeochemistry, and about the formation and behaviour of ‘nanoparticle ...

Synthesis of Sulfide Perovskites by Sulfurization with Boron Sulfides
Chalcogenide perovskites (CPs), with the general composition ABX3, where A and B are metals and X = S and Se, have recently emerged as promising materials for application in photovoltaics. However, the development of CPs and their applications has been hindered by the limitations of available preparation methods.
