On the correlation between the enantiomeric excess of L-isovaline and the level of aqueous alteration in carbonaceous meteorites

Frontiers in Astronomy and Space Sciences
A positive correlation was observed between the enantiomeric excess (ee) of L-isovaline (L-iVal) and the degree of aqueous alteration (AqA) of carbonaceous meteorites.

The Winchcombe meteorite, a unique and pristine witness from the outer solar system

Science Advances, 2022
Direct links between carbonaceous chondrites and their parent bodies in the solar system are rare. The Winchcombe meteorite is the most accurately recorded carbonaceous chondrite fall. Its pre-atmospheric orbit and cosmic-ray exposure age confirm that it

Determination of strewn fields for meteorite falls

, 2021
When an object enters the atmosphere it may be detected as a meteor. A bright meteor, called a fireball, may be a sign of a meteorite fall. Instrumentally observed meteorite falls provide unique opportunities to recover and analyse unweathered ...

Kivesvaara C2 chondrite: silicate petrography and chemical composition [PDF]

Bulletin of the Geological Society of Finland, 1983
Fragments of the Kivesvaara meteorite were said to have been found in Paltamo, northern Finland in 1968. The chemical and mineral composition and the textural features show that this meteorite is a rare C2 carbonaceous chondrite.

The Non-carbonaceous–Carbonaceous Meteorite Dichotomy

, 2020
The isotopic dichotomy between non-carbonaceous (NC) and carbonaceous (CC) meteorites indicates that meteorite parent bodies derive from two genetically distinct reservoirs, which presumably were located inside (NC) and outside (CC) the orbit of Jupiter ...

History of the solar nebula from meteorite paleomagnetism [PDF]

Science Advances, 2017
Meteorite measurements suggest that magnetism played a central role in mass transport in the early solar system. We review recent advances in our understanding of magnetism in the solar nebula and protoplanetary disks (PPDs).
