Deposition, Diagenesis and Structures of the Cheese Bay Shrimp Bed, Lower Carboniferous, East Lothian

Abstract
Synopsis: The laminated dolomites and mudstones in the Lower Carboniferous succession containing the Cheese Bay Shrimp Bed are interpreted as the deposits of a thermally stratified freshwater lake or brackish lagoon in which clastic/organic laminites accumulated. Drainage systems in the area were probably disrupted by volcanic activity, and seismic activity strongly affected the semi-consolidated sediments to produce a variety of pull-apart, fold, fault and sediment injection structures. During diagenesis intense dolomitisation of the laminites and associated sediments took place.
