This pocket-sized geological field guide provides an introduction to the Tertiary igneous rocks of the spectacular Ardnamurchan peninsula of Scotland. The introductory chapters describe the various intrusive igneous rocks which are encountered, their age relationships and petrogenesis. Seven excursion itineraries cover the three main centres of igneous activity which are well exposed on the peninsula, as well as their metasedimentary country rocks and younger Mesozoic cover sequence. In the back of the book sits an A3 fold-out map of the tertiary igneous complex of Ardnamurchan.
