### Scientists find the source of one of the rarest meteorites to fall on Earth​

The Ivuna meteorite landed in Tanzania in December 1938 and was subsequently split into a number of samples – one of which is housed at the Natural History Museum (NHM) in London.

Based on an analysis of an asteroid known as Ryugu, experts believe the Ivuna rock may have originated from the edge of the solar system.

Professor Russell said that apart from Ivuna, only four other known CI-type meteorites exist on Earth: Orgueil and Alais, which both fell in France, Tonk which fell in India, and the tiny Revelstoke meteorite which fell in Canada.

Ryugu belongs to a class of asteroids called carbonaceous, or C-type, asteroids.

C-type asteroids are rich in water, carbon and organic compounds from when the solar system formed.

The researchers said both Ryugu and the CI chondrites originate from the same region of space – the outskirts of the solar system – and cannot rule out the possibility that they could even share the same parent body.

Professor Russell said: ‘By comparing the forms of iron in both the asteroids and meteorites, we learned that Ryugu is a remarkably close match to CI chondrites.’

The Buseck Center for Meteorite Studies at Arizona State University has a piece of Ivanu.

Perhaps @DennisN has a sample?
Maybe you are thinking of @davenn and not me?
I'm not collecting meteorites. Yet. Don't give me any funny ideas, I could end up doing that too, who knows. :)

If I start to collect meteorites, I will let you know.
And if I do, I think it will be a somewhat rocky start for me.

hey guys... awww go on Dennis, start collecting, LOL

No, definitely don't have a piece of that. I suspect even a gram of it would cost $1000's I did just buy another meteorite piece this morning. Junction City, Georgia, USA It's a new observed fall a couple of weeks ago That was US$280 - AU$476 ... the US$ to AU$exchange rate sux at the moment, almost double the price there was a 12.8g piece available for US$2500 ... too rich for me hahahaha

I suspect even a gram of it would cost $1000's When I was searching for information on the Ivuna meteorite, I found several places that were selling pieces, each on the order of 1 gram. Apparently, there were many pieces. Someone is selling a 4.552g specimen for$17,900. The description is: IVUNA Type of the Meteorite: CI1, Carbonaceous chondrite (Ivuna groupe, type 1), regolith breccia. Country: Tanzania. Date of find: 1938, december 16 (17h30). Tkw: 704g. Story of the Ivuna meteorite, Tanzania. 1938, december 16 (17h30), two or three stones fell at Ivuna, near the W shore of Rukwa but one of 704g stone was recovered. Ivuna is the classic standart of the "I" designation of Carbonaceous chondrites ( Orgueil is another example of the "I" designation ).

I think the description (IVUNA Type) is a bit dodgy. I'd want a spectral analysis for committing to a purchase for that kind of price. And I would NOT pay that kind of money.

There are more meteorites from Tanzania, but not necessarily related to Ivuna.

crazy huh

stone broke

Adjective

1. What you'll end up as if you buy too many meteorites.
