The distribution and geochemistry of platinum-group elements at the Cretaceous-Tertiary boundary.
The globally-deposited clay layer marking the Cretaceous-Tertiary boundary has been studied to determine the mineralogical carrier phases for the anomalously concentrated platinum-group elements, the affinity of these elements for organic complexes in low temperature environments, the degree of terr...
