The provenance and trace element signatures of MORB anorthitic plagioclase

In an attempt to understand the phase equilibria and petrogenesis of MORB anorthitic plagioclase, Cr-spinel commonly hosted within anorthitic plagioclase has been investigated petrographically and compositionally.

Potential of VIS‐IR imaging spectroscopy and SEM‐EDS and EMPA to map the mineralogical composition of NWA 7317 (CR6)

Meteoritics &Planetary Science, Volume 61, Issue 6, Page 1026-1044, June 2026.
Abstract Asteroid compositional analysis relies on comparing reflectance spectra with laboratory data from well‐characterized meteorites. To advance this comparison, we performed a comprehensive laboratory analysis on a slab of the Northwest Africa (NWA) 7317—CR6 carbonaceous chondrite.

Microbially induced sedimentary structures in fluvial settings: the gas domes from the Bolzano Megacaldera (Permian, Italy)

Sedimentology, Volume 73, Issue 4, Page 914-944, June 2026.
ABSTRACT Gas domes serve as some of the earliest and most persisting indicators of life on Earth, yet their documentation in continental environments remains sparse. This study aims to bridge this gap by examining gas domes within the Permian fluvial succession of Monte Luco, located in the caldera of the Bolzano Supervolcano. These structures occur as
