Pallasite
Year found: 2016, recognized 2017
Country: Eastern Kenya
Mass: hundreds of kilos
Coordinates: 1°5’41.16"N, 39°6’8.30"E
History: In 2016, two brothers were searching for their camels and came across several large, dense stones west of the village of Habaswein and south of Sericho, Kenya. There are no rocks in this area, so they decided they were meteorites. They spent several weeks collecting them with engine hoists and moving them to their homes in Habaswein. Though recognized as meteorites in 2016, the masses had been known to camel-herders for decades. One village elder said that as a child, he and his brothers would play on top of the stones. In early January 2017, Michael Farmer received an email showing a photo of “giant pallasite” weighing 107 kg. He traveled to Nairobi and purchased this stone. Two weeks later he returned to Kenya with Moritz Karl and traveled to Habaswein. Here they were shown more than one ton of specimens stacked in the courtyards of two house compounds. To date, more than 2800 kg has been found.
Physical characteristics: To date, masses ranging from <1 to 500 kg have been found in a strewnfield >45 km long, starting several km west of Habaswein and south of Sericho in Isiolo County. The smaller pieces were found nearer to Habaswein, but still in Isiolo County. The villagers continue to find pieces, mostly on the surface. The majority of the pieces are >50 kg. The meteorites found on the surface show minimal weathering, with patches of fusion crust on the metal. Most stones are blocky, exhibiting a few broad regmaplypts. Several flight-oriented specimens were found, including a 129 kg and two 16 kg stones.
Petrography: Slices from several stones show similar metal/olivine ratio, averaging near 70 areal% olivine and <1 areal % chromite. One 15 × 21 cm slice shows regions with ~95 areal% olivine. Olivine grains are largely rounded, less commonly euhedral, and gemmy green to orange. Grains are typically 0.5 to 1 cm across, though a few range up to 4 cm. One slice shows a 5-cm cruciform-shaped chromite. Metal is dominated by swathing kamacite around the olivine, with pockets of dark-etching plessite. Rare metal-rich regions show well-developed Widmanstätten pattern. Accessory troilite and schreiberstite. No large metal veins or metallic masses have been seen.
Geochemistry: (L. Garvie, A. Wittmann, D. Schrader, ASU) Olivine Fa12.3±0.1, FeO/MnO=57.4±5.4, Cr2O3=0.03±0.01, n=15; kamacite Ni=7.1±0.6 wt%, Co=0.81±0.02 wt%, P=0.06±0.02 wt%, n=17; and schreibersite (Fe1.51Ni1.45Co0.01)P, n=3.
Classification: Pallasite, low weathering.
Here we offer an excellent complete piece of 712 grams of Sericho meteorite shower. Piece is a bit hummered and lightly sandblasted to clean the surface rust.SHIPPING:1. Within USA will be $9.2. To all rest of the World will be $36. GOOD LUCK.
