The role of aerodynamical phenomena in shaping and sculpturing Australian tektites

An empirical model for the Australasian tektite field

“…The longer the journey through the atmosphere, the smaller and flatter the australite. This model, proposed by Baker (1958), has been demonstrated to be plausible by Chapman (1971). The more irregularly shaped tektites were derived from fragments which had solidified before entering a zero gravity regime.…”

Stratigraphic relations of australites in the Port Campbell Embayment, Victoria

“…Many of the specific localities were first found or reported by Baker (1937Baker ( , 1946Baker ( , 1956Baker ( , 1968 who, individually or working with friends, collected thousands of specimens now deposited in the Museum of Victoria. The original shapes and structure of some of these specimens are exquisitely preserved and have provided much of the material for Baker's pathfinding studies of their aerodynamic sculpture (Baker, 1956(Baker, , 1958.…”

Smallest known complete australite

“…The lightest australite is 10,000 times lighter than the heaviest (Baker 1962) (Baker 1958). On the other hand, the forms of the microbeads (spheres, spheroids, ellipsoids, etc.…”

“…The location is 143°10'30" E. and 38°36'45" S. in the region whence seven australites were described by Baker (1968a) A quarter of a century ago, the lightest known australite was 0-0645 gm (Baker 1946 …”
