OXIDES AND SILICATES OF RARE AND RARE-EARTH ELEMENTS IN ALKALINE ROCKS OF THE ILMENOGORSKY BLOCK (SOUTHERN URALS) [PDF]
Минералогия, 2017 A significant part of the REE and rare elements in the rocks of the Ilmenogorsky block forms its own minerals. Oxides and silicates of rare and rare-earth elements in alkaline rocks of Ilmenogorsky block (Southern Urals) include oxynatropyrochlore ...

Controls on carbonate island formation and evolution: South Joulter Cay, Great Bahama Bank
The Depositional Record, EarlyView.The evolution of South Joulter Cay occurs in three stages: linear ridges shaped by waves and longshore currents, arcuate ridges influenced by tidal currents and channels, and cuspate ridges formed by variable wind and wave directions. These processes are driven by climatic and oceanographic factors.

ZONATION OF FORM AND COMPOSITION OF PYRITE CRYSTALS OF THE BEREZOVSKY GOLD DEPOSIT (URALS) [PDF]
Минералогия, 2018 Morphology, zonation and composition of pyrite crystals from quartz veins, beresites and listvenites of the Berezovsky gold deposit are examined. During the crystallization, the pyrite forms changed following a relatively simple scheme {111} → {111}+{100}

KOM′YA-KURAY GOLD PLACER OF THE ATLYAN GROUP, MIASS RIVER VALLEY, AND PROSPECTS FOR FURTHER EXPLORATION OF GOLD PLACERS OF THE SOUTH URALS [PDF]
Минералогия, 2016 Fifty six minerals were identified in 231 heave concentrates from 30 boreholes of the Kom′yaKuray gold placer of the Atlyan placer group, which have been mined since 1930 to 1960 and additionally explored in 1980s–1990s.

Cooling climate across last interglacial high stands on San Salvador and Great Inagua, The Bahamas
The Depositional Record, EarlyView.Temperature data comparison with last interglacial mollusc clumped isotope data from this study, as well as from Bermuda (Minnebo et al., 2024; Zhang et al., 2021). The ‘later’ and ‘earlier’ ages within MIS 5e refer to Reef II and Reef I, respectively, for Bahamas data.

Mechanisms of near‐normal sea water dolomitisation: Mesohaline‐reflux or syn‐depositional?
The Depositional Record, EarlyView.This study investigates the dolomitisation of the Eocene Dammam Formation on the Arabian Plate using petrographic, mineralogical, geochemical and isotopic analyses. The findings reveal two distinct dolomite types, formed primarily through normal‐to‐mesohaline sea water dolomitisation, challenging previous models such as sabkha‐meteoric mixing.
