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

Primary crustal melt compositions: Insights into the controls, mechanisms and timing of generation from kinetics experiments and melt inclusions [PDF]
, 2017 We explore the controls, mechanisms and timing of generation of primary melts and their compositions, and show that the novel studies of melt inclusions in migmatites can provide important insights into the processes of crustal anatexis of a particular ...

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

MICROINCLUSIONS OF PGM MINERALS IN ANCIENT GOLD PRODUCTS: OCCURRENCE, COMPOSITION, ALTERATION [PDF]
Минералогия, 2015 The PGM microinclusions in ancient gold products from the Urals, Siberia, Azov region and Turkmenistan are compared with similar inclusions from the Middle East artifacts. Microinclusions were found in the archaeological sites, which are located close to

Experimental constraints on amphibole stability in primitive alkaline and calc-alkaline magmas [PDF]
, 2017 Equilibrium crystallization experiments were carried out on two primitive basaltic rocks (APR16: Na2O+K2O=4.40 wt%; CM42: Na2O+K2O=2.59 wt%) with the aim to investigate the amphibole stability in the differentiation processes at deep crustal level, of
