Acapulcoites are a group of the primitive achondrite class of stony meteorites. The acapulcoites are named after the only specimen of the group that was a witnessed fall. The Acapulco meteorite fell on 11 August 1976 ...
Acapulcoites, named after the Acapulco, Mexico, fall of 1913, and lodranites, named after the Lodran, Pakistan, fall of 1868, are closely related, ...
Classification: Primitive achondrite (Acapulcoite) based on oxygen isotopes which are coincident with the acapulcoite/lodranite field, distinguished from lodranite type by the modal abundance of plagioclase and the re...
Acapulcoite is defined as a fine-grained meteorite with an equigranular texture and an essentially chondritic mineralogy, primarily composed of olivine, low-Ca pyroxene, Ca-rich pyroxene, plagioclase, metal, and troil...
Acapulcoites and lodranites represent highly metamorphosed to partially molten chondritic rocks. They are now widely believed to form an evolutionary related sequence from a single parent body.
Acapulcoites and lodranites are igneous rocks recognized as a family (or clan) of primitive achondrites that have common mineralogical, petrographic and geochemical features.
About 53 acapulcoites have been documented. They have a finely-crystalline texture and are composed of a mix of mafic silicate minerals (olivine, pyroxenes, plagioclase feldspar) and metallic iron-nickel.

An acapulcoite is a primitive achondrite belonging to a small group named after the only witnessed fall, the 1.9 kg Acapulco meteorite.
General: The meteorites of this group are named for Acapulco, a primitive achondrite that fell in Mexico in 1976. Since its composition is near to chondritic, Acapulco was initially classified as an anomalous chondrit...
