Writeup from MB 113:

Northwest Africa 17004 (NWA 17004)

Algeria

Find: 2024

Classification: Rumuruti chondrite (R3)

History: The meteorite was reportedly found in 2024 by hunters in Algeria and subsequently purchased by Jasper Spencer in July, 2024 from an Algerian dealer via Facebook Messenger.

Physical characteristics: Dark grayish fragment partly covered with fusion crust.

Petrography: The meteorite shows a fresh dark grayish interior and is composed of well-defined, mostly rounded separated chondrules (apparent mean diameter about 400 µm) and often compositionally zoned mineral fragments set in abundant matrix dominated by Fe-rich olivine. Less abundant are low-Ca pyroxene, diopside and sodic plagioclase. Opaque phases are troilite, pentlandite, and Ti-bearing chromite; no metal detected.

Geochemistry: olivine: Fa30.6±14.2 (Fa1.5-42.0, n=15); low-Ca pyroxene: Fs13.0±7.7Wo0.6±0.4 (Fs3.4-29.3Wo0.2-1.5, n=10); diopside: Fs9.5±0.2Wo46.7±0.8 (Fs9.2-9.8Wo45.2-47.2, n=5); feldspar: An6.9-7.4Ab83.8-87.5Or5.0-9.1, n=3
