A study to assess geological prediction of electrical conductivity using the HiRES Isle of Wight survey data

This report describes an application of the electrical conductivity data recorded during a recent HiRES airborne geophysical survey of the Isle of Wight. The data are used to determine if geological and lithological signatures are contained in the high frequency geophysical measurements. Geostatistical analysis is undertaken in relation to various bedrock identification schemes, allowing central moments and dispersion characteristics to be determined as a function of lithostratigraphical and lithological descriptions. Noting a close association between conductivity and a lithological description of sedimentary bedrock it is demonstrated that a continuous bedrock conductivity across a significant proportion of southern England can be predicted.
