Gravity data obtained in Great Britain by the Anglo-American Oil Company Limited

Abstract

The paper describes the widespread and detailed gravity surveys carried out over much of England by the Anglo-American Oil Company. An account is given of the operating method, and the results in individual areas are analysed in detail. The surveys have been of material assistance in outlining the broad geological framework of the areas, and the gravimeter has been successful in depicting with considerable accuracy minor structural features, notably in southern England and the eastern Midlands. The discovery of several important subsurface tectonic features, hitherto unknown, can be directly attributed to the gravimeter. Gravity surveys of this nature, by indicating areas worthy of further examination, serve as a necessary prelude to detailed investigation by seismic methods.
