Estimating paleogeographic, hydrological and climatic conditions in the upper Burdigalian Vallès-Penedès basin (Catalunya, Spain)

During the evolution of the Vallès-Penedès basin, several transgressive pulses in the upper Burdigalian led to a partial flooding of the western part of the basin, leaving locally sabkha-salina evaporite sediments in the area of the village of Vilobí. Due to its geometric configuration with a restri...
