North American Tektite

A tektiteNatural, silica-rich glasses produced by melting of target rocks and dispersal as droplets during terrestrial impact events. In contrast to most impact glasses, which are found inside or within the immediate vicinity of impact structures, tektites are distal impact ejecta. They range in color from black or dark brown to recovered in North America including Texas (Bediasite) and Georgia (Georgiaite). There are reports of other tektites recovered in North America including the Martha’s Vineyard tektite (Gay Head Cliffs, Aquinnah, Martha’s Vineyard, Dukes Co., Massachusetts). This tektite was possibly transported and not native to the area.
