A review of petrological data available for the Reay District and adjacent areas, Caithness, Scotland

This report provides a review of the petrological data available for the Reay District and adjacent areas of Caithness (Scotland). This work forms part of the multidisciplinary Caithness Devonian and Quaternary project which is an integral part of the BGS’s Integrated Geological Survey’s (North) programme. The report includes a summary of the tectonostratigraphy and petrology of the various metasedimentary and meta-igneous rocks belonging to the Precambrian Lewisian and Red Point inliers as well as the Kirtomy, Strathy, Portskerra and Altnabreac complexes. The petrology of the Pre-Devonian in age Reay Diorite and Strath Halladale Granite igneous intrusions are also reviewed. Petrological and geochemical data for the Devonian sedimentary rocks are also included.
