description Chainpur Overview
Chainpur is an LL3.4 ordinary chondrite meteorite that fell in India in 1907. Its low petrologic type indicates that it experienced relatively little thermal metamorphism on its parent body, allowing many chondrules and other early solar-system materials to remain distinct. Researchers study it as an unequilibrated ordinary chondrite, particularly for evidence about primitive solids, mineral chemistry, and processes operating before planets fully formed.
insights Ranking position
Chainpur ranks #52 of 213 in the Meteorite ranking, behind Alais, ahead of Imilac.
help Chainpur FAQ
What does the LL3.4 classification of Chainpur tell scientists?
LL means Chainpur has low total iron and low metallic iron compared with the H and L ordinary-chondrite groups. Type 3.4 means it experienced limited thermal metamorphism, so many early textures remain distinct.
Why are Chainpur's chondrules important?
Its rounded chondrules are remnants of droplets that solidified during the solar system's earliest history. Because Chainpur was not strongly metamorphosed, researchers can examine those objects with less overprinting than in type 5 or type 6 chondrites.
Where and when did the Chainpur meteorite fall?
Chainpur fell in India in 1907. It is a documented fall rather than a meteorite discovered long after reaching Earth.
How does Chainpur differ from a highly metamorphosed LL chondrite?
Chainpur's LL3.4 material retains clearer boundaries among chondrules, matrix, and individual mineral grains. In an LL6 meteorite, prolonged heating would have recrystallized much of that fine early structure.
