Writeup from MB 109:

Sierra Gorda 041        22°30.11’S, 69°3.17’W

Antofagasta, Chile

Find: 13 Oct 2018

Classification: Ordinary chondrite (L5)

Petrography: The meteorite has brecciated texture. The breccia is composed of fragments of two different lithologies. The dominant lithology is microporphyritic rock with rare relicts of chondrules and inclusions of metal Fe-Ni. The melt pockets and shock veins of silicate glass and opaque phases are present. The minor lithology is a shock-darkened chondrite composed by the chondrule fragments and recrystallized granular matrix corresponding to petrologic Type 5. The fragments of these rocks are glued together by silicate glass with inclusions of mineral fragments and opaque globules.
