The Western Australian Museum in Perth has one of the largest meteorite collections in Australia. They have an amazing tektite display aswell! They've produced a fantastic little booklet called 'Tektites' by Ken McNamara and Alex Bevan. I hear that this is the place to be and I can't wait to visit in the future!

This link takes you to the Western Australian Museum's Tektite and Meteorite page:



Here are some photos, thanks to Des Leong. More to come I hope!

ABOVE: Tektites deserve displays like this! The impact crater is Wolfe Creek, unrelated to the tektite fall, but graphically showing where tektites come from, in the absence of a known (and much larger) source crater in Indchina.

ABOVE: A great image. If you read this webpage then you already know what these show! The tektite on the left exhibits coarse V-grooving (also sometimes termed Anda-type sculpture and also the same as Moldavite Besednice sculpture). V-grooving occurs on the original posterior (back) surface due to ground-etching related to tension stresses formed during the rapid primary solidification from the outside-in. Note the slightly sigmoidal nature of these V-grooves. Read Cleverly, 1986, for more information and images on these etched tektites. The tektite on the right shows U-grooving in an Australite, U-grooving is also commonly found in Philippinites. U-grooving forms due to ground-etching and relates to lines of weakness caused by re-entry thermal shell loss and is found on the anterior (front) of the tektite. A poor navel is also evident on this specimen with U-grooves emanating from it. Van Koenigswald, 1961b, saw these features in Javanese tektites (they also occur in Philippinites) and termed them "drop marks". Van Koenigswald assumed these features formed by "drops" striking the surface. This is clearly not the case - these etched lines of weakness are in some way related to shell loss.

ABOVE: The biggest tektite in Australia. Imagine the energy involved - this tektite was flung an estimated 5,800 km from the yet to be discovered impact site. Unsurprisingly the smallest tektites are known from Port Campbell where superbly preserved tektites show practically zero signs of etching.
