至于狄南统的出盆地而言它的历史闻名的活跃在石炭系盆地沉降。NE-SW趋势盛行了硅谷有一个不断发展的地堑。北扩展操作在盆地南部导致混合走滑和外延的发展机制。它进一步产生广泛的计算折叠和NE-SW扳手的缺点。Pitland故障被认为是最主要断层从弗斯。NS-SW断层与盆地轴造成强大的沉积构造控制。区域地形导致更高的侧面中部南部山谷地堑和南部高地。它也涉及朝鲜和其他被称为苏格兰的高地边界断层山脉。在晚泥盆世裂谷开始并持续到早石炭系。然而,热沉降盆地的主要流程操作。

As far as the history of Dinantian of Forth Basin is concerned it was known for its active basin subsidence during carboniferous. NE-SW trend prevailing there made the valley an evolving graben. North South extension which was operating on the basin resulted in the development of mixed strike-slip and extensional regime. It further produced broad N-S folds and NE-SW wrench faults. Pitland fault which is considered to be the most major fault runs from Firth to Forth. NS-SW faults are aligned with basin axes which contribute to a strong tectonic control on the sedimentation. Areas to higher topography results in the flank of Midland Valley graben to the South and Southern Upland block. It is also associated with the north and beyond the Highland Boundary Fault which is known as Caledonian Mountains. In Late Devonian rifting was initiated and it was continued till Early Carboniferous. However, thermal subsidence was the dominant process operating in the basin at that time.

The lithostratigraphical units of each unit of Forth Basin involves Kinneswood formation, Ballagan Formation, Clyde Sandstone formation, Fife Ness Formation, Anstruther Formation, Pittenween Formation, Sandy Craig Formation, Pathhead Formation, Lower Limestone Formation, Limestone Coal Formation, Upper limestone Formation and finally Passage Formation. The Kinneswood formation includes predominately cross bedded sandstones which are already deposited in river channels and associated over bank deposits laid down on flood plains. Grey mudstones and siltstones including isolated nodules and beds of ferroan dolomite are present in Ballagan Formation. As far as Clyde Sand stone formation is concerned it include fine to coarse grained sandstones which are predominately white and containing beds of mudstone. It also includes some pebbly sections too. In Fife Ness Formation the sand stones are arranged in fining-upward cycles. The sediments are deposited in the fluvial and lacustrine environments. Anstruther formation has cycles of mudstone, siltstone and sandstone.
