Chondrule - Wikipedia
A chondrule (from Ancient Greek χόνδρος chondros, grain) is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids.
Chondrule | Meteorites, Formation, Structure | Britannica
Chondrule, small, rounded particle embedded in most stony meteorites called chondrites. Chondrules are usually about one millimetre in diameter and consist largely of the silicate minerals olivine and pyroxene.
Chondrules: Important, but Possibly Unfathomable - University …
2017年4月17日 · Chondrules are mysterious little droplets of formerly molten silicate found in chondrite meteorites. Harold C. Connolly Jr. (Rowan University, New Jersey) and Rhian H. Jones (University of Manchester, UK) have written a concise review of the properties of chondrules and ideas for their origin.

2015年1月14日 · Chondrules are the millimetre-scale, previously molten, spherules found in most meteorites 1. Before chondrules formed, large differentiating planetesimals had already accreted 2....
Chondrules: The canonical and noncanonical views
2016年9月30日 · Chondrules are igneous rocks found within chondritic meteorites, which are the most abundant meteorites found on Earth. These rocks provide science with the age of the Solar System and contain a record of the first solids to form and evolve in the earliest time period of Solar System formation.

2024年9月5日 · Chondrules are iconic sub-millimeter spheroids representing the most abundant high-temperature dust formed during the evolution of the circumsolar disk. Chondrules have been the subject of a great deal of research, but no consensus …
A Process for Chondrule Formation in Meteorites - Astrobiology
2024年11月19日 · Chondrules are small, spherical mineral grains found in meteorites, and are a major component of chondrites. Understanding how the minerals are formed can provide details about the evolution of the early Solar System. The recent study focused on roughly 650 chondrules cut into thin sections.

2017年4月19日 · Chondrules are the most abundant component of chondrite meteorites. The term chondrule comes from the ancient Greek word for the kernel of a grain of wheat, χονδρος (chondros), which chondrules roughly resemble in size and shape. Chondrules are rounded, millimeter, or submillimeter stone particles.
Chondrule - an overview | ScienceDirect Topics
Chondrules are the most abundant component of most chondrite groups, up to 80 vol%. They are submillimeter-sized, igneous spheres and rounded objects that consist predominantly of the ferromagnesian silicate minerals olivine and pyroxene, plus feldspathic glass and blebs of Fe,Ni metal and Fe-rich sulfides (Fig. 4).
The formation conditions of chondrules and chondrites
2008年1月1日 · Chondrules, which are roughly millimeter-sized silicate-rich spherules, dominate the most primitive meteorites, the chondrites. They formed as molten droplets and, judging from their abundances in chondrites, are the products of one of the most energetic processes that operated in the early inner solar system.
