The Cadomian orogeny was first defined over 60 years ago to describe the earth movements which resulted in an unconformity between an Upper Proterozoic supracrustal sequence, namely the Brioverian, and Cambrian molasse in the north Armorican region. Since that time the terminology has been extended to encompass an extensive orogenic cycle lasting from approximately 700 - 450 Ma recorded in a belt running from the northern Appalachians to Armorica and the Southern British Isles. 

This volume is the first to collect together the views of workers from a variety of geological disciplines working on a range of aspects of Cadomian geological evolution. The 27 contributions contained provide both reviews and detailed studies of such topics as basement/ cover relationships, nature of supracrustal sequences, deformation, metamorphism and magmatism. Lithological, geochemical, geochronological and palaeomagnetic data presented allow petrogenetic and evolutionary models to be erected and assessed and correlations to be considered within the Cadomian belt so that global geodynamic evolutionary models may be postulated. The volume thus provides an essential reference to current thinking on the Cadomian orogeny and the date to guide future research.
