	In the Scottish Borders, along the northern margin of the Northumberland–Solway Basin and underlying the Tweed Basin, the oldest Carboniferous rocks, of Tournaisian age, belong to the Inverclyde Group. They include the basaltic lavas of the Kelso Volcanic Formation (‘Kelso Traps’) and the Birrenswark Volcanic Formation which overlie red-bed strata assigned to the Kinnesswood Formation. The latter rests either conformably on red-bed strata of Devonian age (Stratheden Group) or with marked angular unconformity upon an irregular surface eroded across the steeply dipping, Lower Palaeozoic turbidite sequence. Stratigraphically above the lavas lies the Ballagan Formation, which forms the upper part of the Inverclyde Group. This earliest Carboniferous sedimentary succession of the Tweed and Solway basins is distinct from the rest of the Carboniferous succession in being lithologically similar to coeval successions in the Midland Valley of Scotland. Accordingly, the same lithostratigraphical formational terminology is applied ([[Media:P912386.jpg\|P912386]] and [[Media:P912348.jpg\|P912348]]).
