Determine the Elemental Composition of Minerals From Complex Solid‐Solution Series by Raman Spectroscopy: Implications for Mars Exploration Missions

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1404-1417, November 2025.
This study presents a hierarchical Raman‐based classification model for determining the elemental composition of garnets within complex solid‐solution systems. The workflow combines spectral preprocessing, dimensionality reduction, and two‐level classification: first distinguishing between pyralspite and ugrandite groups, and then classifying ...

MRMinerals and MineralTD: Machine‐Readable Mineral Formula and Compositions Data Set for Data‐Driven Research

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
We present MRMinerals and MineralTD, two open‐access, ML‐ready mineral data sets. Together, they provide machine‐readable formulas and 10,000+ compositions per mineral, enabling scalable, data‐driven approaches for applying ML to mineral data analysis. ABSTRACT Artificial intelligence (AI) is being increasingly applied in the geosciences, particularly ...

MIAROLITIC MINERALS FROM THE MALY KUYBAS MAGNETITE SKARN DEPOSIT [PDF]

Минералогия, 2015
The Maly Kuybas magnetite skarn deposit is located in the Magnitogorsk mining district (Southern Urals) 15–18 km northeast from the town of Magnitogorsk. The exploitation of the deposit began in the 1970s and the open pit is currently exploited.

Isotopic analysis of tochilinite (carbonate and magnetite) in Winchcombe: Temperature constraints on early‐stage aqueous alteration in the CM parent body

Meteoritics &Planetary Science, Volume 60, Issue 10, Page 2359-2375, October 2025.
Abstract We report the first oxygen isotope measurements of tochilinite (δ17O: 11.0 ± 2.1‰, δ18O: 23.5 ± 4.0‰ and Δ17O: −1.1 ± 1.2‰) in a CM chondrite (Winchcombe, lithology C [CM2.2/2.3]). We analyzed type‐I tochilinite‐cronstedtite intergrowths (TCIs)—formed by pseudomorphic replacement of kamacite.

Uranium Addition and Loss in Serpentinites: The Potential Role of Iron Oxides

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 9, September 2025.
Abstract Fluid‐mobile uranium serves as a tracer for water‐rock alteration in serpentinized mantle rocks, which constitute an important uranium reservoir. However, the mechanism for uranium addition, where uranium is hosted, and the stability of the uranium enriched material during subduction is not settled.
