These small objects are not extra-terrestrial in origin, but are formed from country rocks that have been melted by the intense temperatures formed by meteoric impact. They can also be formed by rocks ejected from erupting volcanoes that have been blasted so far into the atmosphere that they display fusion crusts from the heat of re-entry.

Black glassy objects similar to obsidian but displaying a tell-tale fusion crust, these are the most common of all tektites. They are found at a number of sites in the far east, including Moung Nong, Thailand and Bam Lake in Tibet. |

First discovered by western scientists in 1926, these black glossy stones (known as Star Dung) had been known and highly prized by natives for centuries.
Australite - Flinders Range, South Australia

Described by Charles Darwin in 1844 current thinking is that these flanged button shaped objects may have originated from the Tycho area of the Moon. |
