Chondrite - Wikipedia
WEBA chondrite / ˈ k ɒ n d r aɪ t / is a stony (non-metallic) meteorite that has not been modified, by either melting or differentiation of the parent body. [a] [1] They are formed when various types of dust and small grains in the early Solar System accreted to form primitive asteroids.
Chondrite | H-Group, Stony-Iron & Achondrite | Britannica
WEBChondrite, in general, any stony meteorite characterized by the presence of chondrules. The only meteorites classified as chondrites that do not contain chondrules are the CI group. These meteorites are so heavily altered by water that it is unclear whether they once contained chondrules.
Meteorite - Chondrites, Achondrites, Iron-Nickel | Britannica
WEBAug 14, 2024 — Meteorites are classified as chondrites on the basis of the presence within them of small spherical bodies (typically about 1 mm [0.04 inch] in diameter) called chondrules. From their shapes and the texture of the crystals in them, chondrules appear to have been free-floating molten droplets in the solar nebula.

WEBTesting a suspected chondrite with a powerful rare earth magnet is always our first step when hunting for meteorites in the field. Ordinary chondrites are classified according to the amount of iron they contain, and are divided into three groups: H, L, and LL; with "H" indicating a high iron content and the "L" and "LL" types containing lower ...
Chondrite - an overview | ScienceDirect Topics
WEBChondrites are meteorites that provide the best clues to the origin of the solar system. They are the oldest known rocks—their components formed during the birth of the solar system ca. 4,567 Ma—and their abundances of nonvolatile elements are close to those in the solar photosphere.

WEBStony meteorites known as chondrites are by far the most common type of meteorite found. Some characteristics of chondrite meteorites — fusion crust, flowlines, and regmaglypts — weather away quickly and are usually found only on stones that haven't been on Earth for very long.

WEBJan 1, 2018 — Definition. Chondrites are the most common type of meteorites, making up around 80% of all known meteorite falls. Chondrites are stony meteorites and most are dark brown, gray, and/or black in color. Chondrites are accreted material from nebular components formed within the dusty cloud that circulated around the young Sun.
