THE ROB GRANT COLLECTION

Written By Aubrey Whymark 2007-2017
These tektites, many of which are exquisitely preserved, were found in undisclosed Australian locations. They have evidently suffered very little terrestrial abrasian.

Australite Anteriors

On the anterior surface of an australite you can see the ring waves. These represent laminar flow in the middle, then turbulent flow on the margins. On exceptionally preserved specimens you can also see radial flow lines.

Bowls

The small bowl-form tektites represent the last stages of ablation. The whole of this tektite is effectively a flange that has folded in on itself.

Wide Flanges

Wider flanges are typically found in the most distal parts of the strewnfield. At greater distances the tektite was travelling faster and traversed more atmosphere. There is therefore a greater degree of ablation.

TEARDROP BEDIASITE   

The Bediasite below was obtained by Rob from the post-mistress in the late 1970's.
