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, Volume 61, Issue 9, Page 2303-2335, September 2026.Abstract Carbonaceous chondrites contain phosphorus, whose speciation and thus history remain to be investigated. Phosphorus/sulfur‐bearing assemblages have been reported in carbonaceous CM chondrites, but there is no consensus about their exact compositions and origins.

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 ...

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2269-2283, September 2026.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.

Journal of Geophysical Research: Planets, Volume 131, Issue 8, August 2026.Abstract Enstatite chondrites record highly reducing conditions in the early solar nebula, yet the origin of their abundant sulfides remains unclear. Niningerite (MgS) and oldhamite (CaS) are ubiquitous in EH3 enstatite chondrites and distinguish them from other chondrite groups.

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1806-1825, August 2026.Abstract This study documents micro‐ to nanoscale observations of primary nebular and secondary parent body iron sulfides in the CR1 GRO 95577. Despite the extensive alteration of the bulk sample, some primary sulfides managed to avoid alteration, having originally formed in the solar nebula during chondrule formation by either fission‐sulfidization or

YARATKULOVO – A NEW H-CHONDRITE IN THE URALS: MINERALOGICAL DATA [PDF]
Минералогия, 2017 The Yaratkulovo meteorite was found in 2016 in the Argayash district of the Chelyabinsk region. It is a «chondrite breccia», in which the light coarse-grained fragments (primary chondrite) occur in the dark fine-grained matrix (impact assemblages ...

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
