Writeup from MB 104:

Huacachina        14°4’59"S, 75°48’54"W

Ica, Peru

Found: March 2014

Classification: Ordinary chondrite (LL3)

History: Antonio Vasquez found the meteorite while driving a car from the Huacachina lake to the ocean. The stone was identified as a meteorite by José M. Monzon, who provided samples for further analysis to Andre L. R. Moutinho.

Physical characteristics: Single stone, weathered exterior. Saw cut reveals numerous chondrules, some up to 3 mm, brecciation and some melt veins present.

Petrography: (C. Agee, UNM) Microprobe examination of a polished epoxy mount shows numerous porphyritic chondrules, many with mesostasis or glass. Mean apparent chondrule size 750±420 μm, n=54.

Geochemistry: (C. Agee and N. Muttik, UNM) EMPA. Chondrule olivine Fa21.9±9.9, Fe/Mn=63±30, Cr2O3=0.05±0.04 (wt%), n=17; low-Ca pyroxene Fs14.8±7.8Wo1.7±1.8, Fe/Mn=34±21, n=13.

Classification: Ordinary chondrite (LL3, W2, S4), Olivine Fa mean value and sigma, and Cr2O3 mean value and sigma similar to Chainpur (LL3.4) in Grossman and Brearley (2005).

Specimens: Main mass with finder, 368 g with José M. Monzon, 620 g with Andre L. R. Moutinho and 25.2 g including microprobe mount on deposit UNM.
