| Abstract/Notes | Examination of two new expanded KT transitions and reexamination of road outcrops near Beloc, Haiti, reveals that deposition of the glass spherule-rich deposit (SRD) occurred within the early Danian Parvularugoglobigerina eugubina (Pla(1)) Zone, followed by an Ir anomaly, and 50 cm above it, a second Pd-dominated platinum group element (PGE) anomaly. The KT boundary is at an erosional unconformity between the base of the SRD and underlying Maastrichtian limestone, where an interval representing about 100250 thousand years appears to be missing (juxtaposition of planktic foraminiferal zones (Pla(1)) and Plummerita hantkeninoides (CF1)). It is possible that the spherule layers are reworked from original deposits at or below the KT boundary. The Ir anomaly is of roughly chondritic-type and compatible with an impact event, whereas the Pd-dominated PGE anomaly is a more basalt-type and compatible with a magmatic origin. This suggests a multi-event scenario consistent with one impact followed by a major volcanic event in the Caribbean or elsewhere. | ||
