On possible parent crater for Australasian tektites: Geochemical, isotopic, geographic and ballistic constraints

Abstract

A set of Australasian tektites (AAT) has been geochemically characterized by methods of activation analysis. Based on the acquired data as well as previously published geochemical, mineralogical, petrographical and isotopic data on both AAT and their potential source materials, and considering geographic and ballistic constraints known from other tektites and their strewn fields, probable source materials and location of the parent impact crater for AAT have been discussed
