Provenance Reassessment of Eocene Turbidites, New Caledonia: Inferences for Obduction Models

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Provenance of pre‐obduction Eocene turbidites from New Caledonia is used to better constrain their geodynamic context and inform debate on subduction polarity. Chemical compositions of detrital clinopyroxenes in arenites are compared against potential sources.

Mineralogically Diverse and Salt‐Rich Regolith in Jezero Crater Characterized Using X‐Ray Spectroscopy

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The Planetary Instrument for X‐ray Lithochemistry (PIXL) onboard the Perseverance rover has characterized the composition of Martian regolith at a scale of hundreds of microns using micro‐focus X‐ray fluorescence spectroscopy. PIXL data reveal a diverse population of regolith grains with distinct spectral, chemical, and crystallographic ...

The Use of Ornamental Stone Waste (OSW) as Raw Material for Porcelain Ceramic Tiles Production

International Journal of Ceramic Engineering &Science, Volume 7, Issue 5, September 2025.
ABSTRACT Despite the relevant contribution of the ornamental stone industry to the international economy, the large volume of waste generated during the production process is one of the main problems faced by the sector. Currently, the ceramic industry has shown to be a powerful alternative for the use of these wastes.

Australian continental‐scale heavy mineral patterns track climate, weathering and erosion

Sedimentology, Volume 72, Issue 5, Page 1430-1452, August 2025.
ABSTRACT The heavy mineral cargo of sediment is influenced by a complex and variable overprint of climate and environmental processes acting on weathered crystalline basement sources. Here, a continental‐scale heavy mineral compositional dataset of 1315 surface sediment samples, analysed via automated mineralogy, from across Australia is utilized to ...
