Most deposition occurs during floods - organisms, soil buried rapidly. This is true only if deposition is continuous. Lakes One of the most important terrestrial environments, as they often preserve critical climate information. Salts are product of chemical weathering in adjacent highlands. Lower abundance of burrowing animals relative to marine environment allows excellent preservation of fine-scale layering and other sedimentary features in many cases.
Deserts Deserts are regions of little net deposition.
Desert sediments contain very little organic matter. The marine environment is primarily a depositional environment. Deltas Very rapid deposition of mainly terrestrial detritus. Interplay of fluvial and marine processes commonly results in intermingling of terrestrial and brackish water fossils. Deposition on delta plain occurs in nearly horizontal beds, consists largely of sand and silt.
