Шаблон:Short description Шаблон:Infobox meteorite subdivision Acapulcoites are a group of the primitive achondrite class of stony meteorites.
Naming and history
The acapulcoites are named after the only specimen of the group, with a witnessed fall. The Acapulca meteorite fell on 11 August 1976 at 11:00 near El Quemado Colony (Шаблон:Coord), outside Acapulco, Guerrero, Mexico. It had a mass of Шаблон:Convert. The stone was retrieved 15 minutes afterwards from a Шаблон:Convert deep crater and was cool to the touch.[1] Following that discovery, 52 meteorite specimens have been classified as acapulcoites.[2]
Chemical composition
Acapulcoites are primarily composed of olivine, orthopyroxene, plagioclase, meteoric iron, and troilite.
Like all primitive achondrites, acapulcoites have chemical composition and mineralogical similarities with chondrites,[3] some specimen even show relic chondrules. Their mineral composition lies between H and E chondrites.[3]
