Rum is justly renowned for the ultrabasic cumulate magmas of its Eastern and Western Layered Intrusions of Paleocene age. Less well-known are the equally spectacular sidewall and roof contacts of the magma chamber, together with examples, rare in the geological column, of sequences through the caldera floor of the Rum volcano and the overlying volcano-sedimentary infill (with ignimbrites).
The nine excursions in this A5-sized guide, each colour coded for easy reference, highlight all of the above and also illustrate the complex contacts of the Lewisian and thick Torridonian successions with Paleocene rocks, a feather-edge Triassic succession and Jurassic fault slivers, as well as a plant-bearing Paleocene sequence of lavas and conglomerates that demonstrates very rapid intra-Paleocene unroofing of the Rum Igneous Complex.
