| These natural tektites were collected in the Guangdong Province of China. They have irregular elongate natural shapes that often taper towards one end (drop-like shapes) or have two bulbous ends like a barbell, with natural pitted surfaces. They are known as "Indochinites" (sometimes also called "australiasia" tektites), and have been shown by K-Ar radiometric age dating to be approximately 700,000 years old. Scientists believe that the tektite's origin is the result of meteorite impact on the earth. The tektites then formed when molten material, created by the meteorite's hyper-velocity impact, flew through the air hardening into natural glass with aerodynamic forms and surface features. |
