Chronologies of sedimentary processes in sediments of the FOAM site, Long Island Sound, Connecticut.

Abstract

Determines the distribution with depth of elements, 234Thxs, 7Be, 210Pbxs, 239,240Pu, selected trace elements, 14C (in both shells and organic fraction), pore water sulfate, and the diagenetic reaction products, solid phase organic carbon and sulfur. Shows that in high energy and dynamic sedimentary environments, such as the FOAM site, the results of steady state diagenetic modelling should be accepted only over time and depth scales permitted by the physical evidence.-from Authors
