Writeup from MB 109:
Sierra Gorda 027 22°30.27’S, 69°8.54’W Antofagasta, Chile Find: 24 Oct 2019 Classification: Ordinary chondrite (H5, melt breccia) Petrography: The meteorite is composed of chondrules, chondrule fragments and fragments of recrystallized aggregates of silicates, metal and sulfides; all the components are embedded in a fine-grained interstitial aggregate of pyroxene crystals and feldspar that resembles devitrified melt rock. The mineral grains and the chondrule fragments are intensively darkened due to occurrence of sub-micrometer troilite and metal inclusions that are highly abundant in the matrix as well. The main phases are olivine, pyroxene, metallic Fe, troilite and feldspar; minor chromite. Olivine has strong undulatory extinction. | ||||||||||||||||||||||||||||||||||
