We are a team of meteorite and fossil hunters.We search worldwide for new and known meteorites. Since 1995, we have mounted expeditions to Tsarev, Brahin, Kunya Urgench, Dronino, Markovka, Seymchan, Sikhote-Alin and many others in Russia and nearby. We have also collected many meteorites from North Africa, the Middle East, Europe and ...the United States.We have gathered samples of almost all types of known meteorites, including a large collection of lunar meteorites.We are on the world market since 2000, and on eBay since 2004. We ship worldwide from USA. We easy combine shipping. We accept different ways of payments, but PayPal is very preferred. As always we hope the best is in future.

Ataxite, Iron ungrouped
Year found: 2000, July
Country: Russia, Ryazan region
Coordinates: 54° 44' 48"N, 41° 25' 18"E
A 40 kg iron was found by Oleg Gus’kov, Moscow resident, as he was returning home from collecting mushrooms near the village of Dronino in the Ryazan district. In early 2003, it was taken to Vernad, and identified as meteoritic. In summer 2003, scientific expeditions and meteorite hunters collected more than 600 fragments (the largest is 250 kg) totaling about 3 000 kg and occurring at a depth of 0.2-2 m across an area of 0.5x1.5 km. The distribution of the fragments suggests that the meteorite formed a now-buried crater about 30 m in diameter. This crater is not reflected in the present-day topography of the site. No historical records exist of a meteorite fall, thus it appears likely that the meteorite fell earlier than the 12th century when the area was largely unpopulated. Classification and mineralogy (D. Badyukov, M. Nazarov, Vernad; J. Wasson, UCLA): the Dronino iron is an ataxite containing sulfide inclusions (~10 vol.%) and consisting of kamacite (7.0±0.5 wt% Ni and 0.75 wt% Co) and rare taenite (26.5±0.5 wt% Ni and 0.35 wt% Co) as elongated precipitates (1-3 μm in size) which form linear and banded textures; sulfide inclusions (up to a few mm in size) rounded and elongated along the banding; accessories are chromite and Fe phosphate (graftonite?); no phosphide was found and P is not detectable in metal with EMP; INAA data: Ni 98.1, Co 5.54 (mg/g), Cr 37, Cu 32, Ga <0.3, As 3.52, W 0.38, Ir 1.68 ppm, Au 0.284 (μg/g); the meteorite is most close to IVA irons in Ni, Ir and the low P but the low Au and Ga contents distinguish the Dronino element pattern from that of all known iron meteorite groups. Dronino meteorite fragments are heavily weathered and covered with rust 1-3 cm thick. Sulfide nodules are surrounded by Fe hydroxides, which replace metal. Troilite of the nodules is commonly replaced with unknown Fe, Ni sulfides.
Here we offer a piece of Dronino meteorite. It is sandblasted and well prepared.
The weight is 990 grams. SHIPPING:1 Within USA will be $9.2 To the rest of the World will be $36.
GOOD LUCK.
