Definition of Armorican in English:
1.1 Geology another term for Hercynian.
- This zone is typified by Cambro Ordovician rift-related volcanism and Ordovician to Devonian subduction attributed to a southern proto-Tethys ocean separating the Armorican - Barrandian microcontinents to the north from Gondwana.
- In Cambrian rocks archaeocyathans are found in an equatorial and subequatorial belt which included Laurentia, and the North African, Iberian and Armorican parts of Gondwana, but not the Avalonian part.
- Heavy-mineral analysis of the sands clearly indicates a possible Armorican contribution at this time but according to Daley they are unlikely to be of fluvial origin because ‘the latter was periodically separated from Britain’.
