Turkish Meteorite Fall?

There's a recently posted ILKE HABER AJANSI video of Dr Peter Jenniskens collecting suspected meteorites in Bingöl, Turkey.

Anyone know anything more?

Great if it is a Howardite fall...only 16 ever recorded.

Yes, interesting. I see Howardites are:

From the Meteoritical Society web site, the recommended classification Howardite means:

"An achondrite from the howardite group."

The highlighted words are defined as follows:

achondrite: A stony meteorite that lacks chondrules and originated on a differentiated parent body.

howardite: Howardites are an abundant group of polymict-breccia achondrites that appear to represent mixtures of eucrites + diogenites (these three linked groups are collectively known as HED meteorites and may come from asteroid 4 Vesta). The main minerals in howardites are pyroxene (largely orthopyroxene) and Na-poor plagioclase. A minority of howardites are rich in solar-wind noble gases and thus inferred to be regolith breccias.


The associated Near Earth Object bolide and fireball database report is here.

[Edited to remove unrelated video].

There's a brief report, in Turkish and provided by aHaber, into the hunting activity around Bingöl here.

There's a couple of videos of the hunting here and here.

Some wonderful looking stones....but I think the last looks like a fake...looks like somebody has been out with a blowtorch and melted something slag like on the stone.

Hi Graham,

My mistake. The third video (link now removed) was old and unrelated to the current fall. So, the images are all good.

Ah!...that would explain it...some of the fusion crust on this Howardite...if that's what it is looks fantastic...large contrasting areas of jet black gloss against duller velvet.

There are a number of reports about the cottage industry that has sprung up around the Turkish fall site.


There's a report about the fall from The University of Istanbul.
