Gubbio, Italy
AB Platinum metals (Pd, Ir, Pt) and Au were determined by radiochemical
neutron activation analysis (RNAA) on Cretaceous-Tertiary (K-T) boundary
samples collected at Gubbio, Italy.  In addition, about thirty elements
were determined by instrumental NAA (MAA) for both the Cretaceous and the
Tertiary layer samples, as well as the boundary clay samples.  Iridium and
other Pt metals were observed to be similarly enriched, relative to
CI-chondrite, in the boundary layers, i.e., they occur in chondritic
ratios.  On the other hand, correlations among the metals are not very
good, suggesting that Pt metals were not incorporated into clay materials
in a single phase, but rather, they behaved separately according to their
own solution chemistries.  In the Gubbio section, the chemical composition
does not change so much across the K-T boundary layer, except for Ir (and
possibly other Pt group elements) and is very similar to that of the
''North American shale composite (NASC)''.  Arsenic and Sb were observed
not to be anomalously enriched in the Gubbio K-T boundary layers.  This
implies that their abundances cannot be a clue in elucidating an event
which must have happened at the K-T boundary period.  NASC-normalized REE
abundance patterns for the boundary samples show characteristic features
due to some REE precipitation out of seawater. REE abundances are not
variable among the Cretaceous, the Tertiary, and the boundary samples,
suggesting that conditions for precipitation and sedimentation were similar
across the K-T boundary at Gubbio.
