P226 HiRES-1 AEROMAGNETIC DATA INDICATE NEW GEOLOGICAL STRUCTURE IN CENTRAL ENGLAND R.J. CUSS R.J. PEART and T. PHARAOH British Geological Survey Keyworth Nottingham NG12 5GG UK Abstract 1 The HiRES-1 airborne survey of central England was flown by the British Geological Survey (BGS) in collaboration with World Geoscience (UK) Ltd.
