| dc.description | The Duque de York Complex (DYC) is part ofthe low grade metamorphic accretionary complexes ofthe pre-Andean Patagonian 'basement'. lt is a sedimentary succession exposed along the westem margin of southemmost South America. New U-Pb zircon ages and palynological data restrict the maximum depositional age ofthe DYC to the limit between the early Permian (Kungurian) and the middle Permian (Roadian). The palynological association recorded in the DYC, characterized mainly by Gymnospermopsida pollen, indicates ahumid environment offorestwith an undergrowth offerns. Regional paleogeographic correlations point out that an interpretation ofDYC asan autochthonous terrane cannot be discarded, contrasting with previous hypotheses which suggest an allochthonous character for this complex. | en-US |
| dc.description | El Complejo Duque de York (CDY) forma parte de los complejos metamorficos acrecionarios del 'basamento' pre-Andino de la Patagonia, correspondiendo a una sucesion sedimentaria que aflora a lo largo del margen occidental austral de Sudamerica. Nuevas edades U-Pb en circon, en combinacion con informacion palinologica, permiten acotar la maxima edad de deposito posible del CDY al limite entre el Permico temprano (Kungnriaoo) y el Permico medio (Roadiaoo). La asociacion palinologica registrada en el CDY esta caracterizada por Gymnospermopsida, e indica un ambiente humedo de bosque con sotobosque de helechus. Las correlaciooes paleogeograficas apuntan a que la condicion de terreno autoctono del CDY no puede ser descartada, lo que se contrapone a hipotesis anteriores, las que sugieren un caracter aloctono para este complejo. | es-ES |
