The mean specific gravity of 288 tektites from Guangdong, China was measured to be 2.426. The specific gravities of 49 disc-shaped Guangdong tektites with masses between 10.2 and 246.9 grams obey the equation: SG-20[degrees]C 2.4419 - 0.00914 [log.sub.10][M.sub.A] where [M.sub.A] is the tektite mass in grams. The density of the tektites is in between that of quartz-2.648 and of vitreous [SiO.sub.2]-2.196. This equation is consistent with the higher specific gravities of microtektites and it may show the role that gas bubbles play in determining specific gravity. Bubbles are more likely to be found in larger tektites and probably reduce the specific gravity of larger ...
