Geochemistry characterizes provenance in southern Scotland

Abstract
An understanding of the Ordovician—Silurian development of the Southern Uplands accretionary thrust belt is an essential precursor to reconstructing the British sector of the Appalachian—Caledonian orogen. The British Geological Survey (BGS) has now extended its regional geochemical database to cover this controversial area. Integration of the new geochemical data with results from the current geological resurvey allows fresh insights into the provenance patterns of the Southern Uplands' greywacke sequences and constrains the extrapolation of geological boundaries.
