TL;DR: In this paper, the maturity of the organic matter in matrix, determined by Raman spectroscopy, has been used as a powerful metamorphic tracer, independent of the mineralogical context and extent of aqueous alteration.

TL;DR: A new type of meteoritic material, intermediate in size between meteorites and interplanetary dust particles (IDPs), is described in this paper, which is a new family of solar system objects in a mass range corresponding to the bulk of extraterrestrial material accreted by the earth today.

TL;DR: A database of magnetic susceptibility measurements on different non-ordinary chondrites (C, E, R, and ungrouped) populations is presented and compared to our previous similar work on ordinary chondites as discussed by the authors.

TL;DR: The Paris chondrite as discussed by the authors provides an excellent opportunity to study CM chondrules and refractory inclusions in a more pristine state than currently possible from other CMs, and to investigate the earliest stages of aqueous alteration captured within a single CM bulk composition.

TL;DR: In this article, the structural grade of the organic matter trapped in the matrix, which is irreversibly transformed by thermal metamorphism, has been quantified using a geothermometer calibrated with terrestrial metasediments.
