Description

Iridium in sea-water has been measured (after isolation from the saline matrix by reduction with magnesium) by neutron bombardment, radiochemical purification and high resolution γ-ray spectroscopy. The concentration obtained in a Pacific coastal water was 1.02 +- 0.26 x 10-14 g per g of sea-water. At such extremely low concentrations, seawater is an extremely unlikely source for anomalously high iridium concentrations measured in the Cretaceous-Tertiary boundary layer of deep-sea sediments.
