Murchison Meteorite Display, Exotic Carbonaceous Chondrite

Murchison Meteorite Display, Exotic Carbonaceous Chondrite


On September 28, 1969, a large meteorite exploded over the area of Murchison Australia. Witnesses reported a long smoke trail and a distant tremor on impact. Many small to medium stones fell over a strewnfield approx. 5 miles across. Some of the fresh meteorites smelled of sulphur or had a rotten eggs smell. Later analysis showed that the odor was a sign of aromatic compounds and volatile organics present in the meteorite's matrix. This was the world's largest shower of carbonaceous chondrites of this type at the time. Murchison was classified as a CM2 type of carbonaceous chondrite with the presence of many amino acids and other ingredients that have made it the subject of intense scientific research that continues to this day. It is truly a historic and important meteorite.

This handsome display box measures approx. 3 x 4 inches (75mm x 100mm) and comes with a removeable lid that has a glass viewing window. Inside the display is a color photo of a scientist's gloved hand conducting tests on a sample of Murchison meteorite. A cut-out in the photo contains a micromount fragment of Murchison meteorite. The fragment is contained in a labeled gemjar and can be removed and handled outside of the display.

Refer to the photo. The black centimeter cube is shown for scale and is not included. You are purchasing a display like the one shown. Note, each micromount fragment is unique and may vary slightly in appearance.
