ON MINERALOGY AND PETROCHEMISTRY OF PALEOPROTEROZOIC DIORITE-GRANODIORITE INTRUSIVE MASSIFS OF THE TIM-YASTREBOVSKAYA STRUCTURE OF THE VORONEZH CRYSTALLINE MASSIF
As a result of the study of granitoids of the two-phase Stoilo-Nikolaev complex, confined to the Tim-Yastrebovskaya structure (Voronezh crystalline massif) using the method of X-ray fluorescence spectrometry, as well as the analysis of local micro-X-ray s
Secondery platinum-group minerals from placer of the Bolshoy Sap river (Middle Urals)
In this paper we present textural and mineral chemistry data for platinum-group minerals (PGMs) from a concentrate obtained during mining of a technogenic gold placer near the Pervomaisky dunite-harzburgite massif. The study employed scanning electron mic

Co AND Ni MINERALS IN ORES OF THE MIKHEEVSKOE PORPHYRY Cu DEPOSIT (SOUTH URALS)
Co and Ni minerals are described in ores of the Mikheevskoe porphyry copper deposit (South Urals, Russia). Cobaltite–gersdorfite series (CoAsS–NiAsS), violarite (FeNi2S4), millerite (NiS), pentlandite (Ni5.5Fe3.4)∑8.9S8.0, and melonite (NiTe2) are identif
Unravelling the organic and inorganic signatures of Mennouna Coal: A comprehensive approach for sustainable utilization
This study investigates the mineralogical and organic composition of coal samples collected from the Mennouna region in the Bechar-Kenadsa sub-basin, in southwestern Algeria (31° 29′ nord,2° 74′ ouest). Twenty-two coal samples were obtained from a depth o
TRACE ELEMENT COMPOSITION OF BERYL FROM SPODUMENE PEGMATITE DEPOSITS IN KUNAR PROVINCE, AFGHANISTAN
The study of the trace element composition of beryl from the Chambalak and Digal deposits of the Darai Pech pegmatite field of the Kunar province using the SIMS method allowed us to establish the sectoriality of the beryl crystal (sample B2) from the Cham

Distribution of impurity elements by zones and sectors of spodumene crystal growth (Pashki deposit, Nuristan, Afghanistan)
By secondary ion mass spectrometry (SIMS) method, the regular distribution of several chemical elements-impurities in spodumene crystals of one of the lithium pegmatite deposits of Afghanistan – Pashki (Nuristan province) has been analyzed. Twenty seven (
PROCESSING OF GYPSUM RAW MATERIALS IN THE ADMINISTRATIVE AND RELIGIOUS CENTER OF THE BRONZE AGE GONUR-DEPE (SOUTH-EASTERN KARAKUM)
Based on the study of the mineral composition and textural and structural features of samples of an ancient binder mixture used in construction work in Gonur Depe, the technology of its preparation has been reconstructed. The basis of the material is thin

Hydroxyapatite of bone tissue: dynamics of crystallochemical changes in osteoporosis
Bone tissue is a physiogenic organomineral aggregate consisting of organic components (collagen, fats, sugars) and mineral (hydroxyapatite). One of the most common bone diseases is osteoporosis. This disease leads to disruption of bone tissue mineralizati
