Writeup from MB 111:

Zagora 011 30°18’28"N, 5°32’50"W

South, Morocco

Purchased: 2022 March 31

Classification: HED achondrite (Eucrite, brecciated)

History: Found in Morocco on July 5, 2021

Petrography: (K. Metzler, IfP) Fine-grained achondritic breccia, consisting of eucritic lithic clasts with ophitic textures and monomineralic fragments (pyroxene, plagioclase) set in a recrystallized fine-grained clastic matrix of related debris. Most pyroxenes exhibit augite exsolution lamellae. Accessories are troilite, ilmenite, and a silica polymorph

Geochemistry: Mineral compositions and geochemistry: Low-Ca pyroxene (host): Fs_51.2±0.5Wo_2.6±0.4(Fs_50.5-52.2Wo_2.2-3.3); mean Fe/Mn (at.): 32.1; n=10. Ca-rich pyroxene (exsolution lamellae) Fs_22.1±0.5Wo_41.1±0.4(Fs_21.3-22.9Wo_40.3-41.7); n=10. Plagioclase An_89.3±1.5Or_0.2±0.3(An_87.4-91.2Or_0.0-0.8); n=7

Classification: Brecciated eucrite, based on texture and mineral chemistry
