Chondrule size and related physical properties: a compilation and evaluation of current data across all meteorite groups

, 2014
The examination of the physical properties of chondrules has generally received less emphasis than other properties of meteorites such as their mineralogy, petrology, and chemical and isotopic compositions.

Protracted Timescales for Nebular Processing of First-formed Solids in the Solar System

The Astrophysical Journal, 2023
The calcium–aluminum-rich inclusions (CAIs) from chondritic meteorites are the first solids formed in the solar system. Rim formation around CAIs marks a time period in early solar system history when CAIs existed as free-floating objects and had not yet

Alkali‐halogen metasomatism of the CM carbonaceous chondrites

Meteoritics and Planetary Science, 2019
Meteorite Hills (MET) 01075 is unique among the CM carbonaceous chondrites in containing the feldspathoid mineral sodalite, and hence it may provide valuable evidence for a nebular or parent body process that has not been previously recorded by this ...

The Dehydration of Serpentines and Extraction of Water

The Planetary Science Journal
Some groups of carbonaceous chondrites are dominated by phyllosilicates, specifically the serpentine group, which are characterized as alternating layers of silicates, metal cations, and hydroxyl (OH). Both antigorite, an Mg-rich member, and cronstedtite,

Nature's Starships II: Simulating the Synthesis of Amino Acids in Meteorite Parent Bodies

, 2015
Carbonaceous chondrite meteorites are known for having high water and organic material contents, including amino acids. Here we address the origin of amino acids in the warm interiors of their parent bodies (planetesimals) within a few million years of ...

Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

The Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Ground-based Characterization of Hayabusa2 Mission Target Asteroid 162173 Ryugu: Constraining Mineralogical Composition in Preparation for Spacecraft Operations

, 2017
Asteroids that are targets of spacecraft missions are interesting because they present us with an opportunity to validate ground-based spectral observations. One such object is near-Earth asteroid (NEA) (162173) Ryugu, which is the target of the Japanese
