ABSTRACT: The existence of the late Neoproterozoic supercontinent Pannotia (ca. 650-540 Ma) is
controversial. Several proxies for supercontinent assembly and break-up have been recognized.
Global orogeny and granitoid magmatism, detrital zircon and monazite age peaks and extreme
conditions of metamorphism are some of the proxies pointed out for supercontinent assembly.
The amalgamation of Pannotia was accompanied by the Pan African-Cadomian-Baikalian
orogeny that generated several collisional belts. We present a sequence of magmatic and
tectonometamorphic events for the Cadomian belt that can be interpreted as proxies of
supercontinent assembly.
Descrição
AIMS OF THE MEETING: The scientific sessions will be focused on the Pan-African and Cadomian
Orogenies recorded in North Africa and western Europe across the Ediacaran Cambrian transition and its bearing in the assembly and demise of Pannotia.
Contributions dealing with structural, magmatic, provenance sources,
palaeomagnetic, sedimentary, chronostratigraphic and radiometric constraints
are particularly welcome. ORGANIZING COMMITTEE:
J. Javier Álvaro, Instituto de Geociencias (CSIC-UCM), Spain;
Martim Chichorro, Universidade Nova de Lisboa, Portugal;
Gabriel Gutiérrez-Alonso, Universidad de Salamanca, Spain.
