“…A kerogen-oil-gas kinetics model with secondary reaction developed on kerogen 3 in this study was used as kinetics input. Two periods of uplift of the Bowland Shale, in the late Carboniferous/ early Permian and after the Late Cretaceous, have been recognized by Barrett (1988) and Leeder (1988), and the heat flow model was modified after Jarvis & McKenzie (1980). Calibration on vitrinite reflectance is in accordance with a BGS report, which also described 1D modelling on well Grove 3 (Andrews 2013).…”

The Carboniferous Bowland Shale of northern England has drawn considerable attention because it has been estimated to have 1329 trillion cubic feet hydrocarbons in-place (gas and liquids) resource potential (Andrews 2013). Here we report on the oil and gas generation characteristics of three selected Bowland Shale whole-rock samples taken from cores and their respective kerogen concentrates. Compositional kinetics and phase properties of the primary and secondary fluids were calculated through the PhaseKinetics and GOR-Fit approaches and PVT modelling software. The three Bowland Shale samples contain immature, marine type II kerogen. Pyrolysate compositions imply primary generation of paraffinic–naphthenic–aromatic (PNA) oil with low contents of wax and sulphur. Bulk kinetic parameters have many similarities to those of productive American Palaeozoic marine shale plays. The secondary gas generation potential of Bowland Shale is greater than the primary gas potential although it requires a 10 kcal mol −1 higher activation energy to achieve peak production. Primary oil, primary gas and secondary gas reach their maximum generation at 137, 150 and 200°C respectively for a 3°C Ma −1 heating rate. Different driving forces of expulsion including the generation of hydrocarbon and overpressure caused by phase separation during sequential periods of subsidence and uplift could be inferred.

“…Conventional instantaneous plate stretching models 18 predict a present-day lithospheric thickness of less than 40 km (assuming an initial thickness of about 125 km), with the implication that melting and upwelling should be markedly shallower than is observed. However, finite-duration rifting models show that when extension occurs at low strain rates, such as those observed in Afar, the base of the lithosphere may be strongly affected by conductive cooling 28 . We quantify this effect for Afar using a numerical finite-duration rifting and melting model 28,29 (see Methods) to examine how the history of rifting may have affected melt production and plate thinning.…”

We quantify this effect for Afar using a numerical finite-duration rifting and melting model 28,29 (see Methods) to examine how the history of rifting may have affected melt production and plate thinning. This approach adds to the petrological and REE modelling by explicitly examining the relationships between rifting, mantle upwelling, the geotherm (and hence lithospheric thickness) and melting.…”

“…Second, the strain rate profile generated by inverse modeling each well was then forward modeled to generate a subsidence curve for the whole time period, up to the present day ( Figure 6, third panels). The forward model generates the subsidence profile expected if each well behaved as predicted by the lithospheric pure shear stretching model of McKenzie [1978] and Jarvis and McKenzie [1980]. A basin continues to subside after rifting has ceased as thermal reequilibriation occurs; the amount of postrift subsidence is determined by the preceding synrift phases.…”

Cenozoic vertical motions in the Moray Firth Basin associated with initiation of the Iceland Plume

It is likely that the Iceland mantle plume generated transient uplift across the North Atlantic region when it initiated in earliest Cenozoic time. However, transient uplift recorded in sedimentary basins fringing the region can be overprinted by the effects of permanent uplift. Identifying and quantifying transient uplift can only be achieved in areas which have a well‐constrained stratigraphic record and across which the relative importance of permanent and transient uplift varies (e.g., the Moray Firth Basin, North Sea). By analyzing the subsidence of 50 boreholes from the Moray Firth Basin (MFB), residual vertical motions unrelated to rifting have been isolated. Transient uplift of 180–425 m occurred during Paleocene times. The western MFB has also been affected by permanent Cenozoic uplift, with denudation decreasing from 1.3 ± 0.1 km in the west of the basin to zero denudation east of 1°W. Dynamic support above the Iceland Plume led to transient uplift of the entire MFB in early Paleocene times, peaking in latest Paleocene times. In early Eocene times the effect of the plume waned, and subsidence occurred. Paleocene permanent uplift of the NW British Isles is generally accepted to have been due to magmatic underplating of the crust emplaced during the British Tertiary Igneous Province (61–58.5 Ma). The cause of Neogene uplift events is poorly understood, but it could also be associated with the Iceland Plume.
