Abstract: The petrographical and chemical characteristics of the tourmalinite pebbles from the Lower Devonian conglomerates of Belgium are presented together with selected trace element data. The tourmalinites are shown to represent metasomatically altered rocks of variable origin and composition. A model of subvolcanic hydrothermal alteration is proposed.
