Cambrian-early Ordovician volcanism across the South Armorican and Occitan domains of the Variscan Belt in France： Continental break-up and rifting of the northern Gondwana margin

The Cambrian-lower Ordovician volcanic units of the South Armorican and Occitan domains are ana- lysed in a tectonostratigraphic survey of the French Variscan Belt. The South Armorican lavas consist of continental tholeiites in middle Camhrian-Furongian sequences related to continental break-up. A s...
