‘With meteorites, the samples come to us.’ ‘Studying meteorites is the least expensive form of space exploration,’ Dermot says. Its ‘exceptionally rare’ chemical composition-which gives the meteorite its distinctive smell-may well ‘offer clues to the origins of life’.Īnd all this from fragments of a rock which was picked up in cow paddocks. But Dermot-a man who has devoted his life to rocks-ranks the Murchison Meteorite as his favourite in the collection.īecause this is a rock which may well harbour secrets of the formation of the Solar System, Dermot says. The museum holds both lunar and martian rocks. as exciting as Moon dust’.īut over the subsequent decades, its scientific prestige has only mounted from that first impression.įifty years later, Museums Victoria Dermot Henry says that innocuous-looking, remarkable-smelling black rock is now, probably, the world’s most studied meteorite. On the spot, John declared it as ‘almost. To the geologist, it was the unmistakable odour of organic molecules, including amino acids-the building blocks of our DNA. When John opened the bag he was hit with a pungent smell similar to methylated spirits. Within was a chunk of a meteorite that had just exploded above the northern Victorian town of Murchison.

In September of that year Professor John Lovering was disembarking a plane with Moon rock samples when a journalist presented him a plastic bag. On 24 July 1969 the Apollo 11 astronauts returned to Earth with rocks from the surface of the Moon.īut what if they were not the most important rocks collected in the 20th century? What if they weren’t even the most scientifically significant rocks found in 1969? Acta, 157, 56-85.A fragment of the Murchison, perhaps the world's most studied meteorite.

Using this map it is possible to easily see the normally difficult to see phosphate minerals. This virtual microscope is unusual in containing a three element combination x-ray map, where P, Mg and Al have been assigned to the red, green and blue channels respectively. This bulk composition also matches some of the rocks and soils measured in Gusev Crater by the Mars Exploration Rovers (MER) and in fact, this meteorite represents the strongest link between a martian meteorite and the geochemistry of the martian surface determined by remote sensing. Initial studies of NWA 7034 determined that the meteorite's bulk composition coincides with the composition of the average martian crust determined from mission data. Other portions of the breccia contain plutonic lithic clasts such as monzonites and norites, basalts, and impact melt clasts. This meteorite is a breccia with a basaltic bulk composition and initially classified as a porphyritic basaltic monomict breccia clasts containing a wide variety of textures and include gabbros, quenched melts, and oxide rich reaction spherules. Its martian origin was confirmed by pyroxene analyses (Fe/Mn ratios)and noble gas measurements that match measurements of the martian atmosphere. NWA 7034 (otherwise known as Black Beauty) is unique from other martian meteorites and was found in the Sahara Desert in 2011.
