Chondrule - Wikipedia
网页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
网页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. From textural and chemical relationships, it is clear that they were formed at high.
Chondrules: Important, but Possibly Unfathomable - University …
网页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.

网页2024年9月12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.
Impact jetting as the origin of chondrules | Nature
网页2015年1月14日 · The origin of chondrules, the millimetre-scale, once-molten droplets found in most meteorites, has been an enduring mystery in the science of meteoritics.
Chondrule - an overview | ScienceDirect Topics
网页Chondrules are millimeter-scale, previously melted silicates and cooled-very-fast spherules in chondrites. The ages of the chondrules are from 4564.17 ± 0.7 to 4566.7 ± 1 Myr (Amelin et al., 2002; these ages are also determined by the Pb-Pb method; see Box 2.5).
Chondrules: The canonical and noncanonical views - Connolly
网页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.

网页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.
