Lossiemouth Sandstone Formation

Computer Code: LMSF Preferred Map Code: LMSF
Status Code: Full
Age range: Ladinian Age (TD) — Norian Age (TN)
Lithological Description: White, yellow and pink, fine- to coarse-grained sandstones, siliceous at the top and calcareous towards the base. Some massive; some cross-bedded. Sandstone with a bimodal grain-size ("sago pudding" sandstone). Largely aeolian in origin but partly water-lain.
Definition of Lower Boundary: Around Lossiemouth the base of the formation is the base of the predominantly aeolian sandstones above the waterlain sandstones of the Burghead Sandstone Formation. To the south, around Spynie, the base of the formation is the unconformity with the Upper Devonian "Rosebrae Beds".
Definition of Upper Boundary: The top of the formation is the base of the pedogenic beds belonging to the Stotfield Cherty Rock Formation.
Thickness: To 30m
Geographical Limits: Moray Firth area including exposures near Golspie.
Parent Unit: New Red Sandstone Supergroup (NRS)
Previous Name(s): The Sandstones Of Spynie, Lossiemouth And Findrassie (-369)
