The Bragan\u00e7a CAT comprises three types of granulites (recording quite distinct metamorphic histories) and paragneisses with enclosed eclogite boudins. It has undergone five characterizable, main deformation phases during two orogenic cycles, separated by the extensive intrusion of mafic\/ultramafic layered bodies (types 2 and 3 granulites) into a pervasively deformed granulitic lower continental crust (type 1 granulites). Geochronological data obtained on high\u2010grade metamorphic rocks from Bragan\u00e7a and other similar rocks in the Variscan fold belt have been typically interpreted in two different ways: polycyclical evolution, Precambrian and Paleozoic (Variscan), or monocyclical evolution (Variscan). This second hypothesis is in clear contradiction with field evidence, with tectonometamorphic data, and even with some geochronological data, as shown in this article. Thus we suggest that the tectonometamorphic evolution of the Bragan\u00e7a CAT, and, by comparison, of other similar CAT in the Variscan fold belt, took place during two orogenic cycles, one Precambrian (Grenvillian? Pan\u2010African\/Cadomian?) and another one Paleozoic (Variscan).<\/jats:p>","DOI":"10.1029\/95tc03852","type":"journal-article","created":{"date-parts":[[2004,2,4]],"date-time":"2004-02-04T04:21:48Z","timestamp":1075868508000},"page":"747-762","source":"Crossref","is-referenced-by-count":39,"title":["Geodynamic evolution of the Continental Allochthonous Terrane (CAT) of the Bragan\u00e7a Nappe Complex, NE Portugal"],"prefix":"10.1029","volume":"15","author":[{"given":"Fernando O.","family":"Marques","sequence":"first","affiliation":[]},{"given":"A.","family":"Ribeiro","sequence":"additional","affiliation":[]},{"given":"J.
