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. [2]
The meteorites have been described as "tuff" (compacted volcanic ash). [147] [29] As one example, the Tagish Lake meteorite provided ~10 kg of samples, from a meteor estimated to be 60–90 tons before entry. [148] By contrast, many ordinary chondrite meteorites are tougher [149] and overrepresented. [150] Iron meteorites are even moreso. [151]
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. [11] [12] [13] CM chondrite famous falls ...
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 ...
The Murchison meteorite has been thoroughly studied; it fell in Australia close to the town that bears its name on 28 September 1969. It is a CM2 and it contains common amino acids such as glycine, alanine and glutamic acid as well as other less common ones such as isovaline and pseudo-leucine. [33]
The Maine Mineral and Gem Museum wants to add to its collection, which includes moon and Mars rocks, Pitt said, so the first meteorite hunters to deliver a 1-kilogram (2.2-pound) specimen will ...

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 ...
