Objetivos del presente estudio: 1) identificar las ideas previas del alumnado de magisterio sobre el estructura interna de la Tierra, con especial énfasis en donde se genera el magma que da lugar a los fenómenos ígneos, tanto volcánicos como plutónicos, y que constituye uno de los eslabones fundamentales del ciclo de las rocas, y, por ende, de la dinámica del planeta en el que vivimos. 2) Plantear posibles estrategias de cara a la enseñanza-aprendizaje de los contenidos relacionados con la estructura interna de la Tierra y con la procedencia/residencia del magma que origina los procesos ígneos

Potential mining of the pliocene and quaternary geological formations for the aggregate production along the medium course of the Fluvil river is likely to be carried out through gravel pits. The most significant environmental impacts are envisaged to occur during site preparation and extraction of aggregate. Several environmental impacts types have been considered: variation of water table, reduction of soil and vegetation, development of unbalanced land-forms and deterioration of landscape

This study makes clear the existence of a paleogenical red basal level (Pontils Fm.) in the Vilablareix àrea, under the mio-pliocenical cover of the Girona plain, enlargening the surface known go far of that level

In this paper we make a litostratigraphical study on the Miocene of the 'Vallés occidental' (Barcelona, Spain) which embraces a part of the 'Depresion Media' of the intermediary tectonic grave between the 'Cadena Litoral' and 'Prelitoral' of the 'Sistema Mediterráneo'. At the same time we undertake an analysis of the bassin

There is in this work a description of sedimentological characters of the medium Eocene sandstone level from Sarriá de Ter (Gerona province Spain) and an interpretation of their genesis and situation in the regional paleogeography. The conclusion is that these sandstones form a deltaic channel(delta front). To wards the E and NE the become fluvial deposits, to wards the W, Plana de Vic, they become clay and silstones considered as a prodelta

In this paper we show some sedimentological characteristics of Assilina beds from Armancies Fm. (middle Eocene) and their lateral equivalents that let us to remark some aspects of their genesis. We arrive to the conclusion that, in occidental sector (Bagá-Campdevanol), ‘las barras de Assilinas’ from the Armancies Fm. are grain flow channels, first sedimented at W of Terrades and after slided, from E to W in a turbidite basin, without any coarse clastic

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

The paludal deposits presented here belong to a geomorphological unit identified between Palafrugell Corridor and the littoral plains of Ter River (Baix Ter), associated to a carbonate-rich spring system. The sections show a distintic clay level, mixed with black silts, very rich in snail remains. The malacological assemblage contained stillwaters species (Bithynia leachii, Galba truncatula, Pisidium milium, Radix peregra) along with damp species (Monacha cartusiana, Oxyloma elegans, Succinea putris, Succinella oblonga, Vallonia pulchella, Vertigo sp.). Some open-dry species are also present (Cernuella virgata, Eobania vermiculata, Pomatias elegans, Rumina decollata) revailing a mosaic-like landscape. Radiocarbon dates place this level ca. 7.000BPwithin the Holocene sequence of the Baix Ter basin. Colluvial deposits on top of these paludal levels have a typical open-dry malacological assemblage (Cernuella virgata, Cochlicella acuta, Eobania vermiculata, Pomatias elegans, Rumina decollata, Trochoidea elegans) the same assemblage that inhabits the Empordà littoral plains nowadays

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
