SOME THEORETICAL PROBLEMS OF MINERALOGY [PDF]

open access: yesМинералогия, 2015
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.

Visible and Near-Infrared Reflectance Spectroscopy for Investigating Soil Mineralogy: A Review

open access: yes, 2018
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.

The Mineralogy of Scotland [PDF]

open access: yesNature, 1901
NO book is of more use to the practical mineralogist and collector than one which describes in a detailed manner the mineral localities of a country. Among the best examples are the lexicon of Zepharovich and Becke for Austria; that of Frenzel for Saxony; and, on a much more elaborate scale, the treatise by Lacrox on the mineralogy of France and her ...

INTERGROWTHS OF PLATINUM GROUP MINERALS FROM THE MIASS PLACER ZONE (SOUTH URALS) AND THEIR PRIMARY SOURCES [PDF]

open access: yesМинералогия, 2016
Twenty four platinum group minerals (PGMs) were found in the Kialim and Maly Iremel gold placers of the Miass placer zone, South Urals. Rhodarsenite, bowieite, cuprorhodiste, and xingzhongite(?) were found in the Urals for the first time.

Chemical weathering and provenance evolution of Holocene–Recent sediments from the Western Indus Shelf, Northern Arabian Sea inferred from physical and mineralogical properties [PDF]

open access: yes, 2012
We present a multi-proxy mineral record based on X-ray diffraction and diffuse reflectance spectrophotometry analysis for two cores from the western Indus Shelf in order to reconstruct changing weathering intensities, sediment transport, and provenance ...

COMPOSITION AND MORPHOLOGY OF CRYSTALS OF PLATINUM GROUP MINERALS FROM PLACERS OF THE SOUTH URALS [PDF]

open access: yesМинералогия, 2017
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.
