Abstract
The discovery of altered glass spherules (microkrystites) formed by atmospheric condensation of impact-released vapor at the Cretaceous-Tertiary (K-T) impact boundary by Alvarez et al. (Science 208:1095–1108, 1980) opened the way to the identification of impact ejecta units in Archaean and Proterozoic terrains and thereby investigation of the impact history of the early Earth.
