TitleGeological Map of the Paleozoic of the Central Pyrenees
JournalLeidse Geologische Mededelingen
AbstractThe geology of the map sheets 1:50.000, 1 Garonne and 2 Salat of the Geological map of the Central Pyrenees is described. The stratigraphic sequence consists of Paleozoic rocks from the Cambro-Ordovician to the Carboniferous, and of Mesozoic rocks from the Trias up to the Tertiary. Hercynian and Alpine orogenies have acted on this intercontinental mountain chain. The Hercynian orogeny is accompanied by epi-to cata-zonal metamorphism in which several successive stages can be recognized. The Alpine orogenesis consists also of successive stages of which the Pre-Cenomanian one has been accompanied by basic rock intrusion and a particular kind of metamorphism. In the structure presented on these sheets a stretch of the axial zone is represented and a part of the external zone containing six of the satellite massifs, the two units separated from one another by the north Pyrenean fault zone.
