“…13). The medium-large radius folds are of variable length between 5 and 20 km, with separation between hinges of 1 to 2.5 km and weak dips on the flanks [7]. Martínez Arnáiz, 2013 [7] distinguishes a total of 12 loras (Fig.…”

“…The Geopark constitutes a mountain relief, with the lowest area in the Ebro river valley, to the north with 610 m asl compared to 1,377 m by Peña Amaya [7]. The moorlands (high mountains below tree-line) and loras of Mesozoic age are the geological elements that characterize the landscape as culminating forms, and constitute the common element throughout its geography.…”

“…7d), lacking plasticity, is pronounced. The intense fracturing together with their ocherous nature makes them very vulnerable to karstic dissolution; the high content of magnesium carbonate and iron minerals results in abundant terra rosa, which is the basis of soils suitable for cultivation or pasture [7].…”

Las Loras UNESCO Global Geopark (UGGp) is geologically diverse, particularly in relation to water-derived features: springs, karst springs, travertine buildings, waterfalls, caves. In this work, the interactions between geology, geomorphology, structures and hydrogeology are analyzed. These four components are the fundamentals of geodiversity and their interactions provide a conceptual model of hydrogeological functioning at Las Loras UGGp. The most plausible hypothesis is that the system is formed by two superimposed aquifer systems, separated by an aquitard formed by Lower Cretaceous material. The deep lower aquifer formed by the Jurassic limestones only outcrops on the northern and southern edges of the Geopark and in a small arched band to the south of Aguilar de Campoo. It forms a basement subject to intense deformation. The upper aquifer system, formed by outcropping materials from the Upper Cretaceous, is a free aquifer. It is formed by a multilayered aquifer system that is highly compartmentalized by the very disturbed geomorphology of the landscape, constituting each moorland and each lora, an individualized recharge-discharge system. This model explains the base level of the rivers, the abundant number of existing springs and the permanent nature of some rivers, providing the keys to understand the bases of the geoconservation of a rich geological heritage linked to the active processes of the water cycle.

Las terrazas agrícolas o bancales constituyen un elemento esencial de la montaña mediterránea europea. Su construcción y mantenimiento exige mucha energía, dando lugar a culturas basadas en el aprovechamiento cuidadoso y complejo de las laderas. Hoy laderas enteras de bancales se han abandonado y sufren procesos muy intensos de erosión y revegetación, amenazando con arruinar paisajes culturales de gran valor.En el Valle de Bestué (Pirineo central aragonés) se configuró uno de los mejores paisajes de bancales del Pirineo central. Los bancales alcanzaron el 13,1% de la superficie del valle. Se construyeron para el cultivo de cereales y, con ello, poder alimentar a la población local. Se cultivaron hasta los años cincuenta-setenta del pasado siglo y después se aprovecharon como prados de siega. Desde la última década del siglo XX se abandonaron. El cese del cultivo y la ausencia de pastoreo han cubierto de bosques los bancales en muy pocas décadas; el bosque ocupaba el 13,7% del territorio en 1956 y el 48,7% en 2015. Entre las mismas fechas el paisaje ha perdido heterogeneidad y valor cultural. No obstante, aún se mantienen algunos retazos del paisaje de bancales que deberían conservarse, ya que constituyen un compendio del aprovechamiento agrícola de la pendiente y de conservación del suelo.

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