Palaeozoic – Early Mesozoic geological history of the Antarctic Peninsula and correlations with Patagonia: Kinematic reconstructions of the proto-Pacific margin of Gondwana

The Antarctic Peninsula preserves geological evidence of a long-lived continental margin with intrusive, volcaniclastic and accretionary complexes indicating convergent setting from at least the Cambrian to Cenozoic. We examine poorly understood units successions Palaeozoic Early Mesozoic develop detailed kinematic reconstructions for this section margin. use existing geochronology, along newly presented UPb detrital zircon combined field correlations between tectonic events across Patagonia proto-Antarctic Peninsula. Gondwana/Pangea was punctuated by crustal block translation, deformation, magmatic pulses (flare-ups) development thick complexes.
