Métodos de reconocimiento del subsuelo

The aim of this workshop is to present the main methods of subsoil studies (namely mechanical and geophysical methods) to the Earth Sciences professorate. These methods frequently involve the use of specific material. The different methods are usually taught in the classroom where there is no real contact between the students and the equipment. Several activities, all of them taking place in surrounding areas of the university campus of Girona, will provide the assistants to the workshop with the opportunity of making measurements with different equipment. These activities will be made in the field so as to contribute to the resolution of a problem which will have been previously proposed. The problems presented are situations, most of them real, when subsoil investigation techniques are usually used. These cases have been employed as teaching-learning strategies with university and second grade students in the area of Girona. Finally, some examples of exercises involving the treatment of data obtained through subsoil investigation techniques are also presented to complement the workshop

Las cuevas prehistóricas de Serinyà (Pla de l’Estany, Girona)

The Reclau Caves, which form part of the Serinyà Prehistoric Caves Park (Pla de l’Estany, Girona), are shelters formed by waterfall travertines which have been in turn affected by karstification phenomena. Though relatively small, these cavities were big enough to held human occupation. Its evolution has seen the falling of blocks and infilling of terrigenous materials. Thus, the caves were completely filled and had most of their original roofs fallen. The first excavations of these caves were made in the mid 1940s and they continued, albeit with some interruptions, until present times. The caves were occupied by humans since the late Middle Pleistocene until the Holocene. Hence, the main occupation periods can be attributed to the Middle Paleolithic and Upper Paleolithic cultures. Given the existence of these sites, the project of an archeological park was started and its first phase opened to the public in the summer of 1997. The creation of this park has led to the protection of the three main caves of the site (Arbreda, Mollet and Reclau Viver Caves). The caves have also been adapted and singposted to open them to the public. Other facilities of the park include a reception building and an activity area. The caves can be visited in guided tours which include the projection of a film, the visit to the permanent exhibition room, the three main caves and the participation in some prehistoric-related activities

Lectura ambiental de la cartografía geológica

Geological and geomorphological maps are, apart from a source of scientific information, a necessary tool in order to take proper decisions to solve the geo-environmental problems that arise when dealing with territorial planning. In this paper, the social and economical utility of such maps is described, and some exercises meant for Science of Earth and Environmental Sciences students are proposed

Reconocimiento geofísico del deslizamiento de Rosiana (depresión de Tirajana, Gran Canaria)

The landslide of Rosiana is considered the largest slope movement amongst those known in historical times in Gran Canana, Canary Islands. It has been activated at least 4 times in the last century, and in the movement of 1956, when about 3.106 m3 of materials were involved, 250 people had to be evacuated and many buildings were destroyed. The present geological hazard has lead to specific studies of the phenomenon which, once characterised, can be used as a guide for the scientific and technical works that are to be made in this or similar areas. This paper wants to increase the knowledge about the unstable mass of Rosiana by using geophysical techniques based on the method of seismic by refraction. The geophysical measues have been interpreted with the aid of the available geomorphologic data, thus obtaining a first approximation to the geometry of the slope movements

Aplicació de tècniques geofísiques electromagnètiques a la localització de zones afectades per abocaments incontrolats de residus

Increase of the metropolitan area of cities provoking a progressive settlement of zones that previously had a different territorial use. These zones are usually located within city houndaries and for many years have been affected hy the waste of many kinds of residues. Qualitative analysis of the electrical behaviour of soil, based on maps and cross sections of apparent conductivity, allows us to locate anomalies generated by the wastes. Moreover, the electrornagnetic techniques (EM-31 and EM-34 Geonics devices) are cheaper than other survey methods. Two examples in the campus of the University of Girona, in the southern area of Girona city, illustrate the environmental problem and the applicability of the geophysical method

Participació de les aigües subterrànies en la gènesi d'ambients palustres continentals: el cas dels prats de Sant Sebastià (Caldes de Malavella, Girona)

The area known as 'prats de Sant Sebastià' is in Caldes de Malavella. It is part of the wetlands located in the south-eastern end of the Selva Basin. Several areas with unusually high conductivity (EC up to 24,500 uS/cm) have been identified in this place. This fact allows highly specialised and comparatively rare botanical species to grow in this area. These saline soils follow a north-south line-up. The geophysical data, obtained with a field conductivemeter (EM 31), show that this superficial line-up continues in the subsoil. In addition to this, the conductivity cartography, made for an electromagnetic exploration depth of 6 meters, shows that the width of the region where these salinity anomalies take place increases in depth. When included in the hidrogeological context of this sector of the Selva Basin, these data bring new elements for the study of the genesis and working of these marshy environments. The model that future research will have to confirm, maintains that the groundwater discharges coming from the underlying hydrogeothermal aquifer are a conditioning factor of the aforementioned phenomenon. This ascending flow of highly mineralised waters (TDS of about 3,500 mg/l) can produce and keep stable the soil salinity

Avaluació dels recursos d'àrids disponibles en medis fluvials mitjançant tècniques geofisiques. Aplicació a la cubeta de Celrà (Riu Ter, Ne Catalunya)

The depth of the water table and the clay content are determinant factors for the exploitability of natural aggregates, such as the alluvial sands and gravels found on the fluvial domain of the Ter River. In this preliminary study, carried out in the Celri basin, we conclude that these variables can be determined by means of geophysical methods and recornmends the use of such methods in studies of regional character

Investigación geofísica de los paleovalles pleistocenos del NE de Cataluña: el ejemplo de la Riera de Tossa (Costa Brava meridional)

The geometry of Riera de Tossa (Costa Brava, Catalonia) Pleistocene paleovalley has been studied by two geophysical prospecting methods: vertical electric sounding (VES-DC) and seismic refraction. The results show the existence of a sudden slope change of the thalweg that permits to differentiate two sections where erosion processes operated in unequal intensity. Based on geological and geomorphological available data, it can be inferred that this slope rupture is caused by the litological control imposed by the alineation of resistant materials, which limited the headward erosion extend of the creek during the Upper Pleistocene
