摘要：Abstract. Borehole core provides detailed vertical data which is used to interpretsubsurface sand body architectures, but assumptions are made on therelationship between the lateral and vertical thickness, and theinterconnectivity of units. The sedimentological complexity of the SherwoodSandstone Group succession in this area, passing between aeolian and fluvialpackages creates local- to regional-scale heterogeneities which will impactflow pathways within the rockmass. Measured thickness in boreholes mightrepresent an architectural element's true maximum thickness or more likely,a partial thickness as a result of incision by overlying facies types or asa result of the borehole sitting towards the margins of individual elements(e.g. tapering margin of channel elements). Length and thickness data weremeasured from a suite of primary core data and secondary published outcropstudies in north-west England. The addition of outcrop studies incombination with the borehole data provides a dataset from which the likelylateral extent of the architectural frameworks within the Triassicsandstones can be extrapolated. The interpreted high resolution sub-seismicarchitecture contributes to an increased understanding of flow pathways andthe effect these may have on groundwater as well as sustainable energytechnologies such as low-temperature geothermal aquifers, carbon storage andenergy storage.
