TL;DR: This paper performed a battery of analyses on 17 samples of the Almahata Sitta meteorite, identifying three main lithologies and several minor ones present as clasts, including a pyroxene-dominated, very porous, highly reduced lithology, a pyrite-dominated compact lithology and an olivine-dominated compressive lithology.

TL;DR: Sutter's Mill is a unique regolith breccia consisting mainly of various CMlithologies as discussed by the authors, which can be used to predict what will be found on the surfaces of C class asteroids such as Ceres and thetarget asteroids of the OSIRIS-REx and Hayabusa 2 sample return missions (which willvisit predominantly primitive asteroids).

TL;DR: In this paper, Nishiizumi and Caffee have reported that the carbonaceous chondrites are unique in displaying several distinct peaks for cosmic-ray exposure (CRE) age groups, and excavation from significant depth and exposure as small entities in space is the best explanation for the observed radionuclide data.

TL;DR: In this article, the most abundant carbona-ceous chondrites are examined and subdivided into eight subgroups (CI, CM, CO, CV, CK, CR, CB and CH) based on major element and oxygen isotopic ratios.

TL;DR: In this article, the authors defined four distinct cosmic-ray exposure (CRE) age groups of carbonaceous chondrites and systematically characterized the petrography in each of the four age groups to determine whether the groups have significant petrographic differences with such differences probably reflecting different parent body (asteroid) geological processing, or multiple original bodies.
