Summary

An integrated petrophysical approach has been adopted to investigate the relationship between bedding at the outcrop scale and the spatial distribution of diagenetic features of the Triassic Sherwood Sandstone Group (SSG) succession in Styrrup Quarry, Bawtry, S. Yorkshire, UK. The findings indicate that the distribution of mineral cements is related to the presence of key erosive bounding surfaces. The small-scale of this outcrop-based study identifies a link between stratigraphy and burial diagenesis. Geostatistical analysis using variography and spatial simulation methods have been used to investigate the spatial variation in petrophysical characteristics of the sandstone succession. The presence of a major erosive surface is consistent with spatial structure indicated by directional variogram analysis and conditional simulation of permeability data. The dissolution of early carbonate has rejuvenated secondary intergranular porosity and produced higher permeability in trough-fill sandstones above an erosive surface.
