Writeup from MB 109:

Chug Chug 022        22°29.37’S, 69°8.20’W

Antofagasta, Chile

Find: 21 Oct 2019

Classification: Ordinary chondrite (L(H)3)

Petrography: The meteorite is composed of well-delineated chondrules with average apparent diameter 410±230 µm (N=110), chondrule fragments and opaque grains embedded in minor fine-grained matrix. Olivine has undulatory extinction and planar fractures; feldspatic glass is partly anisotropic; opaque phases are metal (6 vol%), minor troilite and rare chromite.

Geochemistry: Mineral composition and geochemistry: Olivine is Fa22.7±8.28, PMD Fa 37.7 (N=36) including less ferroan main mass Fa18.8±4.3, PMD Fa 23 (N=28) and untypical Fe-rich objects containing Fa36.3±4.7 (N=8); Pyroxene is Fs14.5±7.61Wo1.17±0.79 (N=23)

Classification: Ordinary chondrite (L(H)3), estimated subtype 3.7. Metal content favors L classification, but the average chondrule size is closer to the H range. Hence the L(H) designation.
