Paul inquires:

"Can anyone recommend a publication that provides a comprehensive
 listing of Potassium-Argon (K/Ar) dates that have been published for
 the North American and Australasian tektites?"

Michael Blood writes:

"K-Ar dating is only applicable to volcanic material,
therefore, It would not be applicable to tektites.

Michael, are you sure???
