Calcimicrobial-archaeocyath-bearing clasts from marine slope deposits of the Cambrian Mount Wegener Formation, Coats Land, Shackleton Range, Antarctica

espanolLos clastos carbonatados de la Formacion del Monte Wegener proporcionan evidencias sedimentologicas, diageneticas y paleontologicas de la destruccion y resedimentacion de un registro carbonatadoo cambrico oculto/no conocido en aguas someras de la region de Coats Land en la Antartida. Este mosaico incompleto podria jugar un papel clave en las comparaciones y correlaciones bioestratigraficas entre el registro cambrico de las Montanas Transantarticas, el bloque Ellsworth-Whitmore y la Peninsula Antartica del continente antartico. Ademas, representa un registro clave en las futuras reconstrucciones paleobiogeograficas de Gondwana meridional basadas en asociaciones de arqueociatos. EnglishThe carbonate clasts from the Mount Wegener Formation provide sedimentological, diagenetic and palaeontological evidences of the destruction and resedimentation of a hidden/unknown Cambrian carbonate shallow-water record at the Coats Land region of Antarctica. This incomplete mosaic could play a key role in comparisons and biostratigraphic correlations between the Cambrian record of the Transantarctic Mountains, Ellsworth-Whitmore block and Antarctic Peninsula at the Antarctica continent. Moreover, it represents a key record in future palaeobiogeographic reconstructions of South Gondwana based on archaeocyathan assemblages.
