Major Element Composition of Georgia Tektites

Clarke and Carron 1 reported the first major element analysis of a Georgia tektite ( USNM 1396) and discussed its composition in relation to analyses of moldavites and the tektite from Martha's Vineyard, Massachusetts. King 2 published an analysis of a second Georgia tektite ( DGA -1), and compared it with the previous analysis of USNM 1396. Clarke and Henderson 3 and King 4,5 have discussed the chemistry of Georgia tektites in relation to tektites from other occurrences and possible parent materials. Zähringer 6 has established identical potassium–argon ages of 34 ± 1 million years for all the North American tektites.
