Petrology and mineralogy of the Viñales meteorite, the latest fall in Cuba
Science Progress, 2021 The new Cuban chondrite, Viñales, fell on February first, 2019 at Pinar del Rio, northwest of Cuba (22°37′10″N, 83°44′34″W). A total of about 50–100 kg of the meteorite were collected and the masses of individual samples are in a range 2–1100 g.

Meteoritics &Planetary Science, EarlyView.Abstract We report the discovery of the second (Al,Cu)‐alloy–bearing micrometeorite, FB‐A2, recovered from Mount Gariglione (southern Italy), representing the sixth such occurrence worldwide. Although chondritic in nature, FB‐A2 differs markedly from previously described microspherules.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

Micromagnetic and microstructural analyses in chondrules of the Allende meteorite
Revista Mexicana de Ciencias Geológicas, 2018 Results of micromagnetic and microstructural studies of individual chondrules from the Allende carbonaceous meteorite are presented. Allende is a member of the CV3 carbonaceous chondrites, and part of the oxidized meteorites with iron in silicates and ...

Statistical tests of chondrule sorting [PDF]
Meteoritics & Planetary Science, 2010 Abstract–The variation in sizes of chondrules from one chondrite to the next is thought to be due to some sorting process in the early solar nebula. Hypotheses for the sorting process include chondrule sorting by mass and sorting by some aerodynamic mechanism; one such aerodynamic mechanism is the process of turbulent concentration (TC). We present the

Surface Geology and Evolution of Asteroid Ryugu: Insights From Hayabusa2 Global Mapping
Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract Rubble‐pile asteroids, characterized by loose aggregates of debris held together by gravity, represent both a significant planetary hazard and a key to understanding planetesimal formation. Geologic mapping of these bodies provides essential insights into their origins, evolution, and surface processes.

3D porosity structure of the earliest solar system material
Scientific Reports, 2022 Carbonaceous chondrites (CCs) contain the earliest preserved Solar System material, and objects containing this material are targets of numerous sample return missions.

Journal of Geophysical Research: Planets, Volume 131, Issue 7, July 2026.Abstract We estimate the cosmic dust flux to Earth through the study of rare micrometeorites that preserve part of their precursor features during atmospheric entry heating, namely unmelted and scoriaceous subtypes. Combining high‐precision mass balance measurements, X‐ray computed microtomography and scanning electron microscopy, we studied mass, size
