SEDIMENTS
Definition
- Marine sediments are composed of both biogenic and terrigenous materials. Biogenic sediments includes the remains of planktic and benthic organisms, which provide a record of past climate and oceanic circulation. Terrigenous material provides a record of humidity-aridity variations on the continents, intensity and direction of winds, and other modes of sediment transport (rivers, glaciers, erosion, etc.).
