Many thanks to Mark Ford for providing this months image. Many of you will instantly recognise the specimen as Libyan Desert Glass
a material found over an area tens of kilometres across in the Libyan Desert. Although a terrestrial material it is certain that it's formation is related to the heat and energy released by a large meteorite impact or detonation. Click here
