Geodiversity of Las Loras UNESCO Global Geopark: Hydrogeological Significance of Groundwater and Landscape Interaction and Conceptual Model of Functioning

Las Loras UNESCO Global Geopark (UGGp) is geologically diverse, particularly in relation to water-derived features: springs, karst travertine buildings, waterfalls, caves. In this work, the interactions between geology, geomorphology, structures and hydrogeology are analyzed. As a result of study, first conceptual model hydrogeological functioning at UGGp presented. The most plausible hypothesis that system formed by two superimposed aquifer systems, separated an aquitard Lower Cretaceous material. deep lower Jurassic limestones only outcrops on northern southern edges small arched band south Aguilar de Campoo. It forms basement subject intense deformation. upper system, outcropping materials from Upper Cretaceous, free aquifer. multilayered highly compartmentalized, constituting individual moorland lora units acting as separate recharge–discharge system. This explains base level permanent rivers abundant important components water cycle representing contribution rich geological heritage location.
