原始,定型和盆式
福斯盆地位于苏格兰米德兰山谷的东部。故障控制的迪南(下石炭统)层序位于第四盆地。这个层序覆盖着较薄的那慕尔和威斯特伐利亚沉积物。
就历史和起源而言,中北海地区有着与地质学领域有关的探索和发现的历史。大部分发现是在上侏罗纪浅海相砂岩和古新世海底扇砂中发现的。在具有侏罗纪烃源岩的地区常常没有石炭系沉积物。但中北海高压东部的石炭系烃源岩发生的可能性不容忽视。煤层气和含油气沉积物更容易在该地区被发现,而且很可能在更深的早石炭纪沉积物中积累。此外,这些地区还可能包含四大盆地内所需的碳氢化合物。本研究的主要焦点是福山盆地早石炭世沉积。

Talagraphic历史
金内斯伍德地层主要包括交叉层状砂岩,这些砂岩已经沉积在河道中,并与在平原上沉积的银矿有关。巴拉干组中存在灰色泥岩和粉砂岩,包括孤立的结核和铁质白云岩层。就克莱德砂岩地层而言,它包括以粗粒砂岩为主的细砂岩,这些砂岩以白色为主,含有泥岩层。它也包括一些卵石部分。在Fife Ness地层中,砂石排列在上升的周期中。沉积物沉积在河流和湖泊环境中。 Anstruther地层具有泥岩,粉砂岩和砂岩的旋回。

Origin, setting and basin type
Forth Basin is located in the eastern part of Midland Valley of Scotland. Fault Controlled Dinantian (Lower Carboniferous) sequence is present in the Forth Basin. This sequence is overlain by thinner Namurian and Westphalian sediments.
As far as the history and origin is concerned the area of Central North Sea has a history of explorations and discoveries related to the field of geology. Most of the discoveries have been made in the upper Jurassic shallow marine sands and Palaeocene submarine fan sands. In the regions having Jurassic source rock carboniferous sediments are often absent. But the possibility of occurrence of carboniferous source rocks cannot be ignored in the eastern part of Mid North Sea High. Coal measures and sediments of hydrocarbon are more likely to be discovered in the area and most probably these will be accumulated in the deeper early carboniferous sediments. Moreover, these may also contain required hydrocarbons within the Forth Basin. Early carboniferous sediments in the Forth Basin are the main focus of this study.

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.
