Abstract

Fragmental rocks associated with the exhumed hearths of the Palaeogene volcanoes of NW Scotland have previously been interpreted as classic examples of vent-filling agglomerates of pyroclastic origin. Mapping and logging of these lithologies at the Ardnamurchan Central Complex indicate that they comprise conglomerates of debris flow origin, interbedded with fluvial–lacustrine units, which developed on a dissected landscape during the volcanic and intrusive activity. Clast-matrix analysis allows the palaeo-topography and drainage systems to be inferred, and palynological data are used to develop a palaeogeographical model for the volcanic landscape. A source-region uplift model links the catastrophic mass wasting events to the shallow emplacement of the central complex intrusions.
