Particle Accretion in Microgravity. I. Particle Sizes and Bulk Densities

The Planetary Science Journal
The precise mechanisms related to the accretion of protoplanetesimals from dust in protoplanetary disks (PPDs) are poorly understood. In order to better understand the early stages of planet formation and the growth of millimeter–centimeter agglomerates,

Report on Antarctic meteorites search around the Sor Rondane Mountains, JARE-29 1988-1989

Antarctic Record, 1990
A systematic search for Antarctic meteorites was carried out by the Asuka winter party of the 29th Japanese Antarctic Research Expedition on the bare ice field around the Sφr Rondane Mountains in the 1987-1988 and 1988-1989 field seasons.

D/H ratios of the inner Solar System [PDF]

, 2017
The original hydrogen isotope (D/H) ratios of different planetary bodies may indicate where each body formed in the Solar System. However, geological and atmospheric processes can alter these ratios through time.

Unique evidence of fluid alteration in the Kakowa (L6) ordinary chondrite

Scientific Reports, 2022
Meteorites preserve evidence of processes on their parent bodies, including alteration, metamorphism, and shock events. Here we show that the Kakowa (L6) ordinary chondrite (OC) preserves both shock-melt veins and pockets of detrital grains from a ...

Identification of Magnetite in B-type Asteroids

, 2010
Spectrally blue (B-type) asteroids are rare, with the second discovered asteroid Pallas being the largest and most famous example. We conducted a focused, infrared spectroscopic survey of B-type asteroids to search for water-related features in these ...

Redistribution of Sr and rare earth elements in the matrices of CV3 carbonaceous chondrites during aqueous alteration in their parent body

Earth, Planets and Space, 2018
We measured the abundances of Sr and rare earth elements (REEs) in the matrices of five CV3 carbonaceous chondrites: Meteorite Hills (MET) 00430, MET 01070, La Paz ice field (LAP) 02206, Asuka (A) 881317 and Roberts Massif (RBT) 04143.

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 ...

The Fine‐Scale Magnetic History of the Allende Meteorite: Implications for the Structure of the Solar Nebula

AGU Advances, 2021
Magnetic fields in the early solar system may have driven the inward accretion of the protoplanetary disk (PPD) and generated instabilities that led to the formation of planets and ring and gap structures.

New Paradigms For Asteroid Formation

, 2015
Asteroids and meteorites provide key evidence on the formation of planetesimals in the Solar System. Asteroids are traditionally thought to form in a bottom-up process by coagulation within a population of initially km-scale planetesimals.

Testing the ureilite projectile hypothesis for the El'gygytgyn impact: determination of siderophile element abundances and Os isotope ratios in ICDP drill core samples and melt rocks [PDF]

, 2013
The geochemical nature of the impactites from International Continental Scientific Drilling Project-El'gygytgyn lake drill core 1C is compared with that of impact melt rock fragments collected near the western rim of the structure and literature data ...
