Aerodynamic "boat" shaped Australite. Found in Lake Torres South Australia / Australia . Australites are the most widely flown tektites in the Australasian strewn field. Therefore, australites are relatively small compared to other tektites in the strewn field; however, they are often aerodynamically shaped. The surface structure is rather fine. Tektites are natural glass, generated by a huge meteorite impact. By hitting the ground the kinetic energy from the meteorite was set free in a huge explosion, that vaporised the meteorite and the surrounding earth surface. Jets of rock steam were ejected from the new born crater. The steam jets cooled down in the higher atmosphere and condensed to glass that rained down up to hundreds of kilometres away from the impact. percact "boat" shape 6.74 g - 32 x 14 x 11 mm scale-cube is 1 x 1 x 1 cm International meteorite collector association member number #3503 !!!
