Geochemical and geophysical investigations of the Permian (Littleham Mudstone) sediments of part of Devon

New geophysical and geochemical data from three deep cored boreholes drilled through the Littleham Mudstone sequence (Permian), are presented together with chemical data from the investigation of a number of uraniferous nodules. This investigation provides new chemical data on the host sediments (mudstones) that contain the nodules. The nodules themselves are scattered throughout the mudstones and have long been known to be enriched in a variety of metals in addition to U and V.The information from the holes provides new data on the geophysical characteristics of these sediments in an area where there are few alternate sources of this information. Additional detailed information,data,examination of available core material and consultation with appropriate staff may be purchased on application
