A geophysical investigation of the Roter Kamm impact crater, Namibia
Meteoritics &Planetary Science, EarlyView.Abstract The Roter Kamm impact crater is located in the southern Namib Desert. The crater has a diameter of 2.5 km and belongs to the category of simple, bowl‐shaped impact craters, with an elevated rim of fractured target rock. The crater's interior is completely buried beneath sediments, preventing extensive surface investigations of the bedrock ...

High pressure minerals in the Château-Renard (L6) ordinary chondrite: implications for collisions on its parent body [PDF]
, 2018 We report the first discoveries of high-pressure minerals in the historical L6 chondrite fall Château-Renard, based on co-located Raman spectroscopy, scanning electron microscopy (SEM) with energy-dispersive X-ray spectroscopy and electron backscatter ...

In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)
Meteoritics &Planetary Science, EarlyView.Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).

CI chondrite Oued Chebeika 002 links asteroids Bennu and Ryugu to common parent body
Meteoritics &Planetary Science, EarlyView.Abstract CI chondrites are a compositionally primitive group of meteorites that have undergone extensive aqueous alteration, providing insights into the evolution of primitive planetesimals. Oued Chebeika 002 is the most pristine CI chondrite to date.

Meteorite Jesenice: Mineral and chemical composition of the fusion crust of ordinary chondrite
Geologija, 2010 The composition of the well-preserved fusion crust of the meteorite Jesenice was characterised by means ofoptical and scanning electron microscopy (SEM). The SEM investigations revealed three structurally distinct layerswithin the crust.

Iron Isotope Constraints on the Structure of the Early Solar System
The Astrophysical Journal Letters, 2023 The recent advent of nontraditional isotopic systems has revealed that meteorites display a fundamental isotopic dichotomy between noncarbonaceous (NC) and carbonaceous (C) groups, which represent material from the inner and outer solar system ...

Ryugu Reference Project: Recommendations from the Measurement Definition Team
Meteoritics &Planetary Science, EarlyView.Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

Classification of stony meteorites and chondrules – the case of meteorite Jesenice
Geologija, 2012 In the first part of the paper there is a description about genesis of meteorites, in particularly about stony meteorites– chondrites, since meteorite Jesenice is an ordinary L chondrite. Chondrules represent main part of the mass ofchondritic meteorites.
