1382 grams.   Martian (shergottite)

TKW 18 kg. Observed fall October 3, 1962, in Zagami, Katsina Province, Nigeria.

Found at the green arrow on this map.

Darryl writes:
On October 3, 1962 near Zagami Rock, Nigeria, a farmer was nearly struck by a meteorite which had been ejected off the Martian surface following an asteroid impact. In 1996, in an announcement which made headlines throughout the world, minute amounts of gas were found trapped in Zagami's matrix which matched perfectly with the signature of the Martian atmosphere as determined by NASA's Viking landers. This is the main mass of Zagami. Weighing 1382 grams. Provenance: Natural History Museum, London; Kaduna Geological Survey, Nigeria; The Robert Haag Meteorite Collection.

The Zagami main mass is LOT 17 in Christie's first dedicated METEORITE AUCTION — Wed., April 20th in London

11*44'2.92"N; 7* 4'46.81"E Kevin, Perhaps this is the exact geographical feature referred to as "Zagami Rock", labeled more generally Zagami Hill. Village 150 meters NE.

On the google earth map I wonder where the town/post office named 'Zagami' is located?

This specimen looks like this is the same Main Mass on page 49 (2.45 kg) of his book, "The Robert Haag Collection of Meteorites". It was his last big picture book - Copyright 2003. The piece Daryl is offering is that same piece only the back "cut" side and a bit of the bottom "cut" edge were further removed/sliced to reduce the weight to less than 1.4 kg that is the NEW Main Mass weight from RH's Zagami piece from what I can tell. The main crust covered profile face is still preserved.

Herbert, thanks, Well, then all Zagami is NHM if it is authentic, even my ~gram is from the main mass. My comment on your question: Do you really think that in the 1990's 11 kg of Zagami would have innocently sat whole in Nigeria :-). Another clue is that Zagami was never even published in the MB ;-) I'd be more surprised if this weren't the largest existing specimen, and would bet, subjectively based on size, crust and interior texture, the most beautiful. However the auction wording mentions main mass in terms of what is held by museums, so it possible there is a similarly sized piece held privately.

@Doug: "Wonder how the NHM got into the provenance here? Via temporary import to GB, perhaps." Indeed, the complete 18kg mass was sent to the British Museum in 1963 and was returned (less a 234g sample) in 1965.

Sad to think Bob is no longer Zagami's illustrious curator, times are changing, for this folkloric meteorite. Wonder how the NHM got into the provenance here? Via temporary import to GB, perhaps. While Zagami's story may be of legendary acclaim - Zagami proved we can all own the real deal!

Holy Crap nice! This "main mass" is likely the largest remaining chunk left from Amigo Bob's big piece (7 kg ?) from Africa. Technically the MM is probably in Nigeria...but to many collectors I suppose this auction piece is the MM for them.

No doubt, one of the crown jewels of meteoritics. But is this 1,3kg specimen really the "main mass" of the stone that had an original mass of 18 kg? According to the NASA "Martian Meteorite Compendium", there were ~11 kg in Kaduna in 1994. If this is the main mass, where has all the other material gone?
