Australia’s Little Space Travellers The Flight Shaped Tektites of Australia
Australia’s Little Space Travellers
Artist’s impression of a falling tektite. Nearing the end of its ablationary heating stage. It has developed into the form of the classical flanged button, and shortly it will have decelerated to the point where heating stops, and it falls the rest of the way as a cold piece of black glass

To the late Dr. George Baker of Melbourne, who correctly deduced the history of the remarkably shaped tektites of Australia, and stood by his interpretation in a time of considerable controversy.
Foreword
It has been said that geological studies have found more mysteries in the history of the Earth than they have solved, and among these one of the most profound are the tektites. Tektites are naturally occurring silicate glass bodies found over large areas of the Earth’s surface called strewn fields. Their origin was the subject of controversy for over a century. Most researchers now agree that tektites were formed when large extraterrestrial bodies collided with the Earth producing an impact crater and a large volume of melted surface sediment or rock, which was ejected or thrown great distances over the Earth’s surface, cooled, and then rained back down to Earth as tektites. The Australasian tektite strewn field (or Southeast Asian strewn field as McColl calls it)
