Geological Formation

Mercia Mudstone Group

Named Rock Formations and Groups

The Mercia Mudstone Group is a middle-to-late Triassic sequence of rock, spanning the Anisian to the Rhaetian age, spread across a series of connected basins from Devon and Somerset north through the Midlands and Wales into the Carlisle Basin, reaching its greatest thickness, over 1,350 meters, in the Cheshire Basin. It consists mainly of mudstone along with siltstone and sandstone, and it carries economically significant evaporite deposits of halite and anhydrite, while beds such as the North Curry Sandstone were historically quarried for building stone.

  • Caused By: Sedimentation, Distribution
    The group crops out widely across England, representing deposition within numerous Triassic basins, some of which are physically connected at depth.
  • Associated With: Triassic, Lead, age Triassic
    The Mercia Mudstone Group is a middle to late Triassic lithostratigraphic group (a sequence of rock strata) which is widespread in Britain, especially in the English Midlands-the name is derived from the ancient kingdom of Mercia which corresponds to that area.
