Eolian sandy lignite and associated sediments from the Miocene of the Lower Rhine Basin Western Germany

Description :
Eolian flats are often encountered along modern shorelines in association with wash-over fans, storm inlets and swamps. A possible ancient analogy to this environmental situation has been confronted in the Miocene sediments in the Garsdorf Quarry, Western Germany. These sediments consist of several facies associations, the uppermost of which is notable due to the occurrence of sandy lignite. The sandy lignite displays several sedimentary structures of presumably eolian origin and is interpreted as an eolian sediment formed during humid conditions on eolian flats. Deposits associated with the sandy lignite include stratified channel-sand, most probably representing storm inlets filled by eolian and ephemeral stream deposits, sheets of faintly laminated sand of wash-over fan origin, and lignite formed in coastal swamps.
