Ichnofabrics in Eocene to Maestrichtian sediments from Deep Sea Drilling Project Site 605, off the New Jersey coast ( USA).

Abstract

Ichnofabrics in the sediments drilled at Site 605 reflect environmental changes. Long-term changes allow the section to be differentiated into four units, and short-term fluctuations define cycles in the range of several decimeters. The composition of the ichnofabrics is controlled by the availability of nutrients within the sediment and by oxygen content within the respiration water. -from Author
