Acapulcoites are a group of the primitive achondrite class of stony meteorites.
Naming and history [ edit ]
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 ( ), outside 16°52′59″N 99°54′00″W / 16.883°N 99.9°W Acapulco, Guerrero, Mexico. It had a mass of 1,914 grams (67.5 oz). The stone was retrieved 15 minutes afterwards from a 30 centimetres (12 in) deep crater and was cool to the touch. Following that discovery 52 meteorite specimens have been classified as acapulcoites. [1 ] [2 ]
Chemical composition [ edit ]
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, some specimen even show relic [3 ] chondrules. Their mineral composition lies between H and E chondrites. [3 ]
