The Carboniferous rocks of NW Ireland (The North West Carboniferous Basin) on the Atlantic margin display evidence for multiple phases of fluid flow through the sedimentary succession. Fluid inclusion studies of vein and fracture fills and diagenetic mineral cements have allowed interpretation of palaeofluid temperatures, salinities, compositions and pressure conditions. Hydrocarbon fluid inclusions are also present, indicating that primary and secondary oil migration has occurred. A range of analytical techniques have been employed to constrain mechanism and timing of the multiple stages of fluid flow along with potential heat sources, allowing the reconstruction of the fluid flow history of the NW Irish Carboniferous.
