“…yr BP. Cores from La Larri paleo-lake, located 3 km to the east of the Marboré Lake, revealed that the paleo-lake developed >35 kyr ago when the valley was dammed by a lateral moraine of the Cinca Valley, and it was drained when the moraine was breached around 11 kyr ago (Salazar-Rincón et al, 2013).…”

“…García-Ruiz and Martí-Bono (2001) Recently, sediment cores from the Marboré Lake demonstrated that partial deglaciation of the Marboré Cirque occurred approximately 13 ka ago, as the Marboré Lake was ice-free 12,700 years ago (Oliva-Urcia et al, 2013) The sediment sequence is composed of laminated silts and shows a significant change in depositional environments around 5500 cal yr BP. Cores from La Larri paleo-lake, located 3 km to the east of the Marboré Lake, revealed that the paleo-lake developed > 35 ka ago when the valley was dammed by a lateral moraine of the Cinca Valley, and it was drained when the moraine was breached around 11 ka ago (Salazar-Rincón et al, 2013).…”

“…En el valle de La Larri existen depósitos sedimentarios glacio-lacustres que estarían relacionados con las fases glaciares posteriores al último máxi-mo glaciar local (Salazar-Rincón et al, 2013), por lo que resultan de gran interés para el estudio de los ciclos glaciares en la zona. Dos aspectos fundamentales que es necesario conocer son el espesor y la extensión de estos rellenos.…”

There is a strong interest in protecting the environment with the aim of its long-term preservation. Sometimes the heritage value of these natural areas is related to their biodiversity as there are restricted ecosystems that depend directly on them. In other cases, a singular geological record might exist, essential for the understanding of certain processes affecting the planet, such as volcanic events or glacial periods. To achieve the protection and conservation of these areas it is necessary to generate knowledge about the distribution of geological materials and groundwater masses, to study the parameters that dominate the behavior of these systems, and then define those elements that require special protection or attention. In these protected environments, research methods with minimal environmental impact should be used. Therefore, indirect methods, such as geophysical techniques, are reliable and complementary tools with a minimum environmental impact and are therefore useful for researching these unique areas. The IGME has conducted several geophysical surveys in different protected environments in Spain with the aim of achieving a better understanding, and thus facilitate their preservation and exploitation in a sustainable manner. In this paper, we present a review of some case studies where geophysical methods have been used. In all the cases, electrical resistivity tomography has been the axis of the geophysical research and stands out due to its great effectiveness. The main objective of this communication is to divulge and increase awareness of the important role that these geophysical methods can play in the sustainable study of these unique places.

“…Los llanos de La Larri (1560 m s.n.m.) provienen de un paleolago originado por el bloqueo hace más de 35 000 años de un valle lateral por la morrena principal del glaciar de Pineta, que se rellenó de sedimentos hasta hace unos 11 000 años, cuando fue drenado tras el retroceso del glaciar (Salazar-Rincón et al 2013). Los sedimentos acumulados durante el Holoceno en el lago de Marboré, situado a mayor altitud (2600 m, Fig.…”
