Abstract:
The oldest sediments cored at Site 605 are upper Maestrichtian argillaceous limestone (Hole 605, Subunit VB). The terrigeneous silt content of the uppermost Maestrichtian is quite low, averaging about 3%, whereas the carbonate content is high, usually greater than 60%; the silt contains only traces of glauconite (Site 605 chapter, this volume). Within Subunit VB a K/T boundary was defined by planktonic foraminifers. It was expected to be spread over an extended vertical interval because of the continental margin depositional setting. Examination by the shipboard party showed that the K/T boundary occurs in Section 605-66-1, between 70 and 75 cm. At the contact, the foraminiferal Globigerina pseudobulloides Zone (PIc) and the Coccolith Cruciplacolithus primus Subzone (CPla) overlie, respectively, the Abathomphalus mayaroensis and Nephrolithus frequens zones (Site 605). However, the thin K/T boundary clay, which is always present in complete sections, was not found, indicating either that the K/T boundary clay was not present or, more likely, that it was washed away during the coring operation.
