Bahía de Lobos
The Last Mexican Meteorite.
In July 2023, I received a series of pieces belonging to a discovery that occurred in the Sonoran Desert (Mexico) in October 2008. For many years, the meteorite had been rejected by at least two internationally renowned researchers, claiming that they were not considered such. However, when we analyzed the samples in our laboratory, they were immediately identified, and we proceeded to carry out their official classification.
It was an ordinary H5 chondrite, recovered in dozens of fragments. After the intense efforts of its owner, the official classification of the meteorite was finally achieved.
Petrography
Sample is an Equilibrated ordinary chondrite containing secondary recrystallized feldspar (~30 μm on average, most appears converted into maskelynite) and accessory Fe-Ni metal, troilite, chromite, and Ca-phosphates.
Geochemistry
Olivine (Fa19.4±0.3, range Fa18.9-20.0, n=16), Low-Ca Pyroxene (Fs17.0±0.3Wo1.2±0.2, range Fs16.6-17.6Wo0.9-1.6, n=17).
Classification: Ordinary Chondrite (H5).
