RE: Dronino meteorite

Blobrana · L

The Dronino meteorite is a classified as an ataxite (iron meteorite). Most of the meteoric iron is kamacite with minor amounts of taenite. The kamacite chemistry contains 7.0% Ni and 0.75% Co, whereas the taenite has 26.5% Ni and 0.35% Co (% of total mass). About 10% of the volume of the meteorite are sulfides. Accessory minerals include chromite and an iron-phosphate, which could possibly be graftonite.

Dronino
Ryazan district, Russia
Found July 2000
Iron, ataxite (ungrouped)
A 40 kg iron was found by Oleg Guskov, 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.
