- W1973299098 abstract "Thermobarometric data are compared with the ∼1100 to ∼500 Ma polyphase mobile belts from three separate areas of Africa and Antartica, which originally lay in close proximity within Gondwana. These areas are all characterized by high-grade gneiss terranes formed at ∼1100 Ma (Grenvillian), which were subsequently reworked to a greater or lesser extent at ∼500 Ma (Pan-African). In Zambia, Malawi, Zimbabwe and western Dronning Maud Land peak metamorphic conditions at high temperatures and pressures were attained betwee 1100 and 850 Ma, followed by isothermal decompression (ITD). In Natal and Mozambique, voluminous collision-related granitoid intrusions emplaced between 1200 and 1000 Ma gave rise to high-temperature, moderate pressure metamorphism, with subsequent near-isobaric cooling (IBC). The tectonic setting of these two distinct P-T-t paths can be interpreted as thrust-related uplift in a collisional setting in the case of ITD and as magmatic accretion, subsequent to collisional orogeny, in the case of IBC paths. Les données thermo-barométriques de trois chaînes mobiles polyphasées d'âges compris entre 1100 et 500 Ma de régions distinctes d'Afrique et d'Antarctique mais originellement proches dans Gondwana, sont comparées. Ces régions sont toutes constituées de blocs crustaux constitués de gneiss de haut degré métamorphique d'âge grenvillien (± 1100 Ma) et ensuite plus o u moins remaniés au Pan-African (± 500 Ma). n Zambie, au Malawi, au Zimbabwe et dans la Terre de Maud-Dronning occidentale, les conditions métamorphiques maximales à hautes températures et pressions ont été atteintes entre 1100 et 850 Ma et ont été suivies par une décompression isothermique (DIT). Au Natal et au Mozambique, des intrusions volumineuses de granitoïdes collisionels se sont mises en place entre 1200 et 1000 Ma, ont provoqué un métamorphisme de haute température à pression modérée et ont été suivis d'un refroidissement quasi-isobarique (RIB). L'environnement tectonique de ces deux cheminements P-T-t distincts peut être interprété dans le cadre d'une remontée à une phase de charriage lors d'une collision dans de la DIT et comme une accrétion magmatique suivant un orogène collisionel dans le cas des cheminements RIB." @default.
