Chondrite - Wikipedia
A 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
Chondrites are the most abundant meteorite class, constituting more than 85 percent of meteorite falls. Like most meteorites, chondrites originated in the asteroid belt where collisions and gravitational perturbations put them into Earth-crossing orbits.
Ordinary chondrite - Wikipedia
The ordinary chondrites (sometimes called the O chondrites) are a class of stony chondritic meteorites. They are by far the most numerous group, comprising 87% of all finds. [1] . Hence, they have been dubbed "ordinary".
We Finally Know Where Most Meteorites on Earth Actually Came …
Oct 17, 2024 · Led by researchers from the French National Centre for Scientific Research, the European Southern Observatory, and Charles University in the Czech Republic, the studies focused on H (high iron) and L (low iron) chondrites, the most common type, accounting for around 70 percent of meteorites.
H chondrite - Wikipedia
The H type ordinary chondrites are the most common type of meteorite, accounting for approximately 40% of all those catalogued, 46% of the ordinary chondrites, and 44% of all chondrites. [1]
Meteorite - Chondrites, Achondrites, Iron-Nickel | Britannica
Jan 18, 2025 · Chondrites are the most abundant meteorites (about 87 percent of stony meteorites) in collections. They also are arguably the most important. In terms of terrestrial rocks, these meteorites seem akin to sedimentary conglomerate s—i.e., fragments of preexisting rock cemented together.
Chondrites – Buseck Center for Meteorite Studies
The chondrites take their name from chondrules, the nearly spherical, silicate-rich particles they contain. They are the most abundant type of stony meteorite, and contain some of the first objects to have formed in the Solar System, including calcium …
Chondrite - an overview | ScienceDirect Topics
Chondrites 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.
Chondrite | COSMOS - Swinburne
Chondrites form the most common type of stony meteorite (the other main type are known as achondrites) and account for roughly 86% of all meteorite falls. They typically contain chondrules, millimetre-sized grains of silicate material that are thought to have condensed straight from the solar nebula , and appear to have remained essentially ...
Chondrite - Meteorite Museum
History: The meteorite was purchased from a meteorite dealer in Morocco. Physical characteristics: Many dark brownish fragments without fusion crust. Petrography: Chondrite composed of chondritic portions surrounded by abundant finely recrystallized metal-rich melt rock veins and pockets.
