Scientific paper

AR-40/AR-39 dating of tektites discovered recently in Cretaceous-Tertiary (K-T) boundary marine sedimentary rocks on Haiti indicates that the K-T boundary and impact event are coeval at 64.5 + or - 0.1 million years ago. Sanidine from a bentonite that lies directly above the K-T boundary in continental, coal-bearing, sedimentary rocks of Montana was also dated and has an AR-40/AR-39 age of 64.6 + or - 0.2 million years ago, which is statistically indistinguishable from the age of the tektites.
