== Southerness Limestone Member (SOLM), Carboniferous, Northern England Province ==
Southerness Limestone Member is part of the [[Lyne Formation]]
=== Name ===
Previously known as the Southerness Beds (Craig, 1956 <ref name="Craig56"> Craig, G Y. 1956. The Lower Carboniferous outlier of Kirkbean, Kirkcudbrightshire.''Transactions of the Geological Society of Glasgow''. Vol. 22, 113–122 </ref>; Deegan, 1970 <ref name="Deegan70"> Deegan, C E.1970.The petrology and sedimentology of the Lower Carboniferous rocks between White Port and Kirkbean, Kirkcudbrightshire. Unpublished PhD thesis, University of Wales, Aberystwyth. </ref> ) and the Southerness Limestone Formation (Lintern and Floyd, 2000<ref name="lintern00" />). The status is changed to that of a member.

=== Lithology ===
Interbedded fossiliferous marine limestone, mudstone and minor siltstone, with thick beds of bioturbated sandstone and prominant algal horizons. See Craig (1956)<ref name="Craig56" />; Deegan (1970)<ref name="Deegan70" />.

=== Stratotype ===
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<ref name="lintern00"> Lintern, B C, and Floyd, J D. 2000. Geology of the Kirkcudbright–Dalbeattie district.''Memoir of the British Geological Survey'', Sheets 5W and 5E, part 6W (Scotland)</ref>, 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]]).

The top of the member has a gradational contact with strata of the [[Gillfoot Sandstone Member]] of the [[Fell Sandstone Formation]] (Figure 10, Column 2).

=== Thickness ===
More than 135 m.

=== Distribution and regional correlation ===
Southerness shore, Southerness, Kirkcudbrightshire, south-western Scotland (Southern Uplands).

=== Age ===
Courceyan to Arundian
