A GRAPHIC PRESENTATION OF THE FACIES MODEL OF SALT MARSH DEPOSITS.

Salt marsh deposits are developed along many tidal flat areas, lagoons, bays, etc. They are characterized by small thickness, special sedimentary structures, high organic content, growth of phanerogamous halophytes, and often by scarcity or absence of microfauna. A graphical representation of a section at Ameland (The Netherlands) is given, as well as radiographs of a sandy (Ameland) and a clayey (California) marsh sample. Little structural difference exists between the two. [ABSTRACT FROM AUTHOR]
