History: Purchased by James Tobin in February 2009 from a dealer at the Tucson Gem show. Petrography: Chondrules and chondrule fragments surrounded by secondary calcite, iron oxides, and void spaces. Secondary material and void spaces occasionally replace chondrule mesostases. Roughly 5-10% of the original metal is still present. Geochemistry: Olivine (Fa19.9±1.0, N=32); orthopyroxene (Fs17.7±1.4Wo1.2±0.7, N=33). Specimens: Cascadia holds 23.8 g in two pieces, in addition to one polished thin section and a mounted butt.

History: (Ziyao Wang) Purchased by Ziyao Wang from Aziz Habibi in Erfoud, Morocco 2018. Physical characteristics: (Ziyao Wang) yellow and brownish colored porous flat stone of 2000 g Petrography: (R. Bartoschewitz, Bart) strong alterated chondritic clasts are set a limonitic terrestrial matrix. The chondritic clasts are composed of gray chondrules (0.3-1.5 mm) in a brown strong weathered matrix with few relict metal and sulphide. The terrestrial limonitic matrix contain individual grains of quartz (rounded and angular), minor terrestrial (Or89Ab11) and chondritic (An13-19Or4-7) feldspar, terrestrial (Fe/Mn39) and chondritic (Fe/Mn15-21) pyroxene, and chondritic olivine. Geochemistry: (R. Bartoschewitz, Bart, P. Appel and B. Mader, Kiel) Olivine Fa18.2 (17.5-19.3; n=32); poor Ca-pyroxene Fs16.7(15.5-23.6)Wo1.4(0.8-1.8), Fe/Mn=24(20-34; n=42); diopside En49Fs6Wo45 (n=1); plagioclase An13-19Or4-7 (n=5); chromite CRAL=85 FFM=83 (n=1).

History: Reportedly this stone was found in Western Sahara in early 2023. Petrography: (K. Metzler, IfP) Equilibrated ordinary chondrite with barely visible chondrules. Many secondary feldspar grains with sizes >50 µm. High amounts of Fe-Ni metal, mostly residing outside of chondrules. Geochemistry: Mineral compositions and geochemistry: Mean olivine composition: Fa19.1±0.3 (Fa18.8-19.7; n=5); mean low-Ca pyroxene composition: Fs16.6±0.1Wo1.5±0.2 (Fs16.5-16.8Wo1.2-1.7; n=5). Classification: H chondrite based on mineral chemistry. Petrologic type 6 due to the equilibrated state of olivine and pyroxene and grain size of secondary plagioclase.

History: The meteorite was purchased from a dealer in Libya. Physical characteristics: Brownish rock partly covered with fusion crust. Petrography: The meteorite shows a strongly recrystallized texture with abundant triple junctions between adjoining mineral grains. Felspar and low-Ca pyroxene often poikilitically enclose olivine crystals. Albitic feldspar grains are typically 100 µm in size and frequently contain thin exsolution lamellae of potassium-rich alkali feldspar. No chondrule structures observed. Accessory phases include kamacite, taenite, troilite, and merrillite. Geochemistry: olivine: Fa17.2±0.1 (Fa17.0-17.3, FeO/MnO=36±1, n=7); low-Ca pyroxene: Fs15.2±0.1Wo3.3±0.3 (Fs15.1-15.4Wo3.0-4.0, FeO/MnO=21±1, n=7); plagioclase: An9.7-14.0Ab80.4-84.0Or5.5-8.2, n=7; K-feldspar exsolutions: An8.9-9.0Ab18.8-24.0Or67.2-72.3, n=3
