Iron, (IVB-ANOM) Ataxite. Chinga was discovered in Tanna Tuva, Russia
in the streambed of the Chinga River, in 1913. Since then, several hundred
pieces have been recovered by meteorite hunters. Most specimens are
ripped shrapnel-like pieces, so the meteorite ripped apart very violently
upon entry. Around 500 kilos are known. This is a very nice ataxite
(no structure). It polished to a near mirror finish. It is also a very
hard meteorite, difficult to cut and very hard to polish.
