Speciation of organosulfur compounds in carbonaceous chondrites [PDF]
Scientific Reports, 2021 Despite broad application of different analytical techniques for studies on organic matter of chondrite meteorites, information about composition and structure of individual compounds is still very limited due to extreme molecular diversity of ...

Nanoscale infrared imaging analysis of carbonaceous chondrites to understand organic-mineral interactions during aqueous alteration. [PDF]
Proc Natl Acad Sci U S A, 2019 Organic matter in carbonaceous chondrites is distributed in fine-grained matrix. To understand pre- and postaccretion history of organic matter and its association with surrounding minerals, microscopic techniques are mandatory.

Origin of Isotopic Diversity among Carbonaceous Chondrites [PDF]
The Astrophysical Journal Letters, 2023 Carbonaceous chondrites are some of the most primitive meteorites and derive from planetesimals that formed a few million years after the beginning of the solar system.

Thermal Alteration of Labile Elements in Carbonaceous Chondrites [PDF]
, 2018 Carbonaceous chondrite meteorites are some of the oldest Solar System planetary materials available for study. The CI group has bulk abundances of elements similar to those of the solar photosphere.

Impact-driven oxidation of organics explains chondrite shock metamorphism dichotomy [PDF]
Nature CommunicationsShocked meteorites can be used to probe the dynamics of the early Solar system. Carbonaceous chondrites are less shocked than ordinary chondrites, regardless of the degree of aqueous alteration.

Origin of Earth’s hydrogen and carbon constrained by their core-mantle partitioning and bulk Earth abundance [PDF]
Nature CommunicationsHydrogen and carbon concentrations in the Earth’s core are yet known. Here we determined their metal/silicate partition coefficients (D) simultaneously under typical conditions of core formation and found that D H and D C diminish in the presence of ...

Developing Carbonaceous Chondrite Asteroid Simulants
Earth and Space 2018, 2018 This paper describes the processes and challenges of producing high-fidelity asteroid simulants. DSI (in partnership with UCF) is producing four families of carbonaceous chondrite simulants: CI, CR, CM, and C2. Britt provided target mineralogies, recommendations for researcher safety considerations, and target physical characteristics of selected ...

Electrical conductivity of carbonaceous chondrites and electric heating of meteorite parent bodies [PDF]
, 1986 The electrical conductivity of samples of the Murchison and Allende carbonaceous chondrites is 4 to 6 magnitudes greater than rock forming minerals such as Olivine up to 700 C. The remarkably high electrical conductivity of these meteorites is attributed
