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.

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 ...

Mineralogy, mineral chemistry, and redox equilibria in ten aggregate particles from asteroid Bennu
Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1905-1927, August 2026.Abstract Examination of 10 Bennu aggregate particles has revealed the presence of many phases which taken together can provide constraints on the oxygen fugacity (fO2) of Bennu samples. Phyllosilicates (saponite and serpentine), carbonates, oxides (magnetite, chromite), sulfides (pyrrhotite, pentlandite), phosphate (hydroxyapatite, Na‐Mg‐phosphate ...

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 1965-1993, August 2026.Abstract Volatile‐rich xenolithic clasts in different types of brecciated meteorites represent unique pristine solar system material. This study investigates the maturity and thermal history of organic matter using Raman spectroscopy and aqueous alteration effects using infrared spectroscopy in the matrix of 15 volatile‐rich clasts (C1 and CM‐like ...

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2016-2047, August 2026.Abstract An unusual chondritic xenolith was found in two sequentially prepared thin sections of a sample from the Krymka (LL3.2) chondrite. The xenolith has a rounded, slightly deformed shape of about 5 mm in apparent diameter and is partially surrounded by a double rim made of an inner fine‐grained silicate‐rich rim and an outer sulfide‐rich rim.

Planetesimal Impact Vapor Plumes and Nebular Shocks Form Chondritic Mixtures
The Planetary Science JournalThe origin of chondrules and the chondritic sedimentary rocks that dominate the meteoritic record is a long-standing problem in planetary science. Here, we develop a physical model for the formation of chondritic mixtures as an outcome of vaporizing ...

Did a Complex Carbon Cycle Operate in the Inner Solar System?
Life, 2020 Solids in the interstellar medium consist of an intimate mixture of silicate and carbonaceous grains. Because 99% of silicates in meteorites were reprocessed at high temperatures in the inner regions of the Solar Nebula, we propose that similar levels of

Revista Mexicana de Ciencias Geológicas, 2018 There is a good consensus about the age of the most primitive materials in the Solar System represented by carbonaceous chondrites. From these, a canonical age of the Solar System of 4567 Ma has been defined.
