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.

A Process for Chondrule Formation in Meteorites - Astrobiology
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.
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).
