Chemical Composition of Tektites

Abstract

IN a recent communication¹, Prof. H. Urey makes the following statement : “Tektites have chemical compositions remarkably similar to those of the more acid sedimentary rocks. This is true for the major and minor constituents. (I have been privileged to see analyses as yet unpublished on these minor constituents.) Such a chemical composition is not produced by any other naturally occurring chemical processes that we know of, except perhaps in very rare and special circumstances”. Similar statements have appeared in other papers dealing with tektites, and give the impression that their compositions can be explained only by the fusion of sedimentary rocks.
