Southerness Limestone Member (SOLM), Carboniferous, Northern England Province
Southerness Limestone Member is part of the Lyne Formation
The partial type section of the Southerness Limestone Member occupies a 0.5 km stretch of coast about 400 m west of the lighthouse at Southerness (NX 968 543 to 973 541). The strata are deformed by a gently north-east plunging anticline within the eastern limb of which are exposed some 135 m of fossiliferous, thin-bedded, calcareous mudstones, siltstones and limestones, with four thin beds of calcareous sandstone (Lintern and Floyd, 2000, p. 78).
Lower and upper boundaries
The base is not exposed, but the boundary is probably gradational with the thinly interbedded siltstones and argillaceous limestones (‘cementstones’) of the Kirkbean Cementstone Member of the Ballagan Formation (Inverclyde Group).
More than 135 m.
Distribution and regional correlation
Southerness shore, Southerness, Kirkcudbrightshire, south-western Scotland (Southern Uplands).
