The Murchison meteorite is a meteorite that fell in Australia in 1969 near Murchison, Victoria. It belongs to the carbonaceous chondrite class, a group of meteorites rich in organic compounds . Due to its mass (over 100 kg or 220 lb) and the fact that it was an observed fall , the Murchison meteorite is one of the most studied of all meteorites .
Presolar grains of the Murchison meteorite. In the 1960s, the noble gases neon [5] and xenon [6] were discovered to have unusual isotopic ratios in primitive meteorites; their origin and the type of matter that contained them was a mystery.
The group takes its name from Mighei (Ukraine), but the most famous member is the extensively studied Murchison meteorite. Many falls of this type have been observed and CM chondrites are known to contain a rich mix of complex organic compounds such as amino-acids and purine/pyrimidine nucleobases.

The exact worth of a meteorite varies depending on the specific type of meteorite in question. An 82-pound iron meteorite originating from an asteroid recently sold for $44,100 — about $540 per ...
Turns out UCLA has "the largest collection of meteorites on the west coast" with over 2,400 samples ... which is a small collection compared to the more than 50,000 meteorites NASA reports have ...
The meteorite fragments are therefore called Ribbeck meteorites. About 200 pieces were collected, totaling about 1.8 kg. The largest pieces weighed 212 g (sample F13) and 171 g (sample F14). [5] First analysis by scientists of the Natural History Museum in Berlin showed that it was an aubrite, a rare group of meteorites.
The meteorite type is similar to that of the 1969 Murchison meteorite in Australia. Unlike Murchison, Sutter's Mill shows clear brecciation: fragments of CM lithologies with different aqueous alteration and thermal processing histories are embedded in a fine grained CM matrix material. The Sutter's Mill meteorite originated from near the ...
