Geología sedimentaria y lugares de ocupación prehistóricos de la cueva de maltravieso (Cáceres, España)

Mancha Flores, Eva 20 May 2011 (has links)
El presente trabajo consta de: petrografía de espeleotemas, análisis de isótopos estables, datación mediante OSL y observaciones de campo (rasgos de paleokarst y descripción de los depósitos detríticos). Los datos aportados han permitido conocer la entrada original de la cavidad, desarrollando la hipótesis de la existencia de un nivel superior cercano a la superficie actual y que se halla colmatado. Este nivel, se comunica mediante una diaclasa con la cueva actual. La morfología de esta diaclasa ha permitido la entrada de luz a esta zona, además de hallar presencia constante de agua, mediante la localización de travertino. Con las dataciones que hemos realizado, redefinen mejor la morfología de la diaclasa y la propia cueva situando el cierre de la cavidad en esa zona en 120 ka aproximadamente. Ello permite reconocer los lugares de ocupación prehistóricos a partir de la morfología original y las futuras áreas de intervención arqueológica. / This work consists of: Petrography of speleothems, stable isotope analysis, dating by OSL and field observations (paleokarst features and description of the detrital deposits). The data provided have shed the original entrance to the cavity, developing the hypothesis of the existence of a higher level near the surface and which is now clogged. This level is communicated through the cave as a joint present. The morphology of these joints has allowed the entry of light into this area, in addition to finding the constant presence of water by the location of travertine. With dating we have made better redefine the morphology of the joints and the cave itself by placing the closure of the cavity in the area at approximately 120 ka. This allows us to recognize prehistoric occupation sites from the original morphology and future areas of archaeological excavations.
