A study of the hydrogeological controls on the Pleistocene Crag aquifer in northeast Norfolk is reported. Geophysical methods, in particular multichannel seismic reflection profiling, have provided useful information on the internal structure of the

Geophysical surveys form a vital component of modern archaeological studies, providing data on the location of surviving sub-surface remains. Unfortunately interpretation of the raw output from geophysical surveys requires considerable expertise and

Summary. Particle-motion plots of shear waves have been studied for the section FG of the FENNOLORA seismic experiment. Shear-wave splitting is observed on some records and the polarization of the first arriving shear waves show two peaks at about N3

Summary. Compressional and shear wave velocities and electrical conductivity have been measured simultaneously on three saturated samples of granite up to 0.4 GPa effective pressure and one of chalk up to 0.04 GPa effective pressure. The velocity–p

Deep boreholes and seismic refraction data are reviewed and used to constrain the interpretation of gravity anomalies in Norfolk. The sub-Carboniferous rocks range from ? Precambrian to Devonian in age, with the Palaeozoic sediments showing shales, m

A simple seismic refraction line some 115 km long has been made across Norfolk to provide constraints on the depth to the ‘igneous/metamorphic’ basement. Shots were fired in the Wash and off the coast near Lowestoft and attempts were made to reco

The rocks bounded by the Main Mantle Thrust and the Northern Suture in northern Pakistan constitute an exhumed section through a Cretaceous volcanic arc. Samples have been collected from all the principal lithological groups of the arc, and P and S-w

Strong early Holocene crustal uplift over the Spitsbergen archipelago reflects disappearance of an ice mass centred just north-east of the archipelago and which decayed rapidly just after 10,000 BP after a maximum extension between 12,600 and 10,000

SUMMARY Possible geological explanations for the negative Bouguer gravity anomaly between Hunstanton and King’s Lynn in north-west Norfolk include a thickening of the Mesozoic succession, a concealed basin filled with Carboniferous sediments, or an
