COMPOSITION AND MORPHOLOGY OF CRYSTALS OF PLATINUM GROUP MINERALS FROM PLACERS OF THE SOUTH URALS [PDF]
Crystals of platinum group minerals (PGMs) of the Os–Ir–Ru and Pt–Fe systems from placer deposits of the South Urals are zonal and relatively homogenous in composition and can contain inclusions of PGE sulfides, arsenides, sulfarsenides, and antimonides.

MAGNESIOHÖGBOMITE (MG,FE2+,ZN)8 (AL,TI,FE3+)20O38(OH)2 FROM ILMENOGORSKY-VISHNEVOGORSKY COMPLEX [PDF]
Rare mineral magnesiohögbomite was found in spinel-sapphirine hornblendites and titanomagnetite clinopyroxenites, which compose the large blocks in tectonic sheets of serpentinites among gneisses of the Kyshtym sequence (Ilmenogosrky-Vyshnevogorsky ...

Visible and Near-Infrared Reflectance Spectroscopy for Investigating Soil Mineralogy: A Review
Clay minerals are the most reactive and important inorganic components in soils, but soil mineralogy classifies as a minor topic in soil sciences. Revisiting soil mineralogy has been gradually required.

SOME THEORETICAL PROBLEMS OF MINERALOGY [PDF]
The old fundamental problems of mineralogy (mineral species, system of mineralogy and phylogeny of mineralogy definitions) are briefly considered in the paper. The understanding of mineral species as a mineral series by J.D.

The PANGAEA mineralogical database
Future human missions to the surface of the Moon and Mars will involve scientific exploration requiring new support tools to enable rapid and high quality science decision-making. Here, we describe the PANGAEA (Planetary ANalogue Geological and Astrobiological Exercise for Astronauts) Mineralogical Database developed by ESA (European Space Agency): a ...

This work describes a novel approach to obtain composite submicrometric structures of nickel hexacyanoferrate integrating trigonal selenium with the aim of enhancing the catalytic efficiency in oxygen evolution reaction (OER). Interestingly, the nanostructures undergo a cube‐to‐sphere transition that optimizes surface properties, leading to superior ...
