Abstract

Metal-rich nodules occur at the Permian-Triassic boundary at Budleigh Salterton on the south east Devon coast. The nodules are present in reduced haloes within the otherwise oxidised Littleham Mudstones. The trace element geochemistry of the nodules and the surrounding mudstones and sandstones have been analysed by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). High accuracy data are available for U, Th and the rare earth elements (REE). In addition, semi-quantitative analysis has also been carried out for another 50 elements. The nodules contain high levels of a number of elements, particularly vanadium, uranium and copper. A preliminary model describing the formation of the nodules is presented.
