Tektites. These green pebble-like stones are formed when a meteorite impacts with Earth,melting the surrounding rocks and throwing them up into the air. The material cools and solidifies into glassy pebbles,often with rounded,aerodynamic shapes as a result of their flight through the air. Tektites are only found in a few areas on Earth,known as strewnfields. These tektites were found on the Indonesian Isle of Billiton,and so are called Billitonites | |
