Tiny Aussie “dish”

Usually bragging rights go to the monsters, but there’s a tiny end of the spectrum that deserves respect as well. I suppose there exists a full gradational transition from macro- to microtektites, but at the scale readily discerned by the naked eye, this is the smallest complete Australite in our collection. This morphology is well-known, and generally termed a “dish”. It is the final remnant of a fully flight-ablated tektite—one that has literally turned inside out, essentially a flanged button that has converted all of its button to flange. Little or none of the primary re-entry material remains unmodified. One might argue that these are a distinctive sub-category of the tektite pantheon: a derivative second-generation form, not just flight-modified, but completely restructured. This specimen is from the Kalgoorlie region of West Australia. Approximately 0.1 gms, 7.9 mm diameter, author’s collection.

About the Author

Norm Lehrman is a recently retired exploration geologist with over 45 years experience. His career involved fieldwork in over 35 countries on every continent except Antarctica. While stationed in Australia, Norm and his wife, Cookie, became interested in collecting Australites, which ultimately led to a generalized passion for tektites, impactites, meteorites and related materials. In 1999 they founded the Tektite Source business (www.TektiteSource.com) which has evolved into one of the world's premier providers of tektite and impactite specimens. Norm has retired to a ranch near Spokane, Washington, where they continue to serve tektite aficionados worldwide.
