Chromite placer occurrences of the Volga-Ural basin – genesis, sources and industrial potential

open access: yesGeoresursy
Chromium is a strategic metal, but more than a half of Russia’s needs are met by imports, so new deposits of chromites, including unconventional placer deposits, are of industrial and scientific interest. Previous studies and current works of the authors

Origin of Platinum Group Minerals (PGM) Inclusions in Chromite Deposits of the Urals

open access: yesMinerals, 2018
This paper reviews a database of about 1500 published and 1000 unpublished microprobe analyses of platinum-group minerals (PGM) from chromite deposits associated with ophiolites and Alaskan-type complexes of the Urals.

Cosmic-ray exposure ages of fossil micrometeorites from mid-Ordovician sediments at Lynna River, Russia

open access: yes, 2014
We measured the He and Ne concentrations of 50 individual extraterrestrial chromite grains recovered from mid-Ordovician (lower Darriwilian) sediments from the Lynna River section near St. Petersburg, Russia. High concentrations of solar wind-like He and

Sulfur‐Enhanced Performance and Durability of SrFe0.75Mo0.25O3−δ/Ce0.9Gd0.1O2−δ Fuel Electrodes for Solid Oxide Fuel Cell

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 1, January 2026.
Conventional Ni‐cermet fuel electrodes in solid oxide fuel cells (SOFC) suffer from poor tolerance toward sulfur impurities. Here, Ni‐free perovskite‐based SrFe0.75Mo0.25O3−δ (SFM)/Ce0.9Gd0.1O2−δ (CGO) fuel electrodes are investigated with and without trace hydrogen sulfide addition.

A geochemical study of the winonaites: Evidence for limited partial melting and constraints on the precursor composition [PDF]

open access: yes, 2017
The winonaites are primitive achondrites which are associated with the IAB iron meteorites. Textural evidence implies heating to at least the Fe, Ni–FeS cotectic, but previous geochemical studies are ambiguous about the extent of silicate melting in ...

Global Copper Deposit Dataset: A New Open‐Source Database for Advanced Data Analysis and Exploration Targeting

open access: yesGeoscience Data Journal, Volume 13, Issue 1, January 2026.
We build a new, open‐source global copper deposit dataset (GCDD), facilitating AI‐driven data analysis for exploration targeting and improving our understanding of copper mineralizing systems and their mappable expressions. The GCDD hosts information about 1483 copper deposits worldwide, capturing key deposit attributes such as location, genetic type ...
