Flanders Moss Peat Formation

Computer Code: FLMP Preferred Map Code: notEntered
Status Code: Full
Age range: Holocene Epoch (QH) — Holocene Epoch (QH)
Lithological Description: Peat, fine- and coarse-textured, dark to pale brown and locally orange, with wood fragments and a wide variety of organic remains also including Sphagnum; wedges laterally in some areas into laminated minerogenic sediments of the Carse Clay Formation.
Definition of Lower Boundary: Unconformable base on various local members of the Forth Clay Formation, Wilderness Till Formation (Main Late Devensian) and bedrock; also transitional base on clay gyttja and laterally passing into laminated minerogenic sediments of the Carse Clay Formation.
Definition of Upper Boundary: At surface or overlain partly unconformably by Holocene transgressive estuarine sand, silt and clay of the Carse Clay Formation including the Letham Silt Member and the Carse of Stirling Clay Member.
Thickness: Veneer at least 7m
Geographical Limits: Surface and buried peats in the Forth (from east of Aberfoyle). Earn (from Dalreoch Bridge eastwards) and Tay (eastwards from just north of Perth) valleys and Forth, Eden and Tay estuaries, Montrose basin areas. (Theoretically many members may be set up to reflect localised developments of peat).
Parent Unit: Britannia Catchments Group (BCAT)
