Catalan volcanic field, in Iberian Peninsula Northeast, has been made during Neogene and Quaternary. It is made up Empordà, la Selva and la Garrotxa Zones, the best volcanic morphology is in the last one because is the most recent. In this paper we explain the volcanic rocks general characteristics, what eruption activity generate it and the final volcanic edifice morphology. Finally, we propose some crops to visit

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

A series of circumstances which converge in a little valley in the province of Girona, result in a peculiar type of morphogenetic evolution and a quite singular mechanical instability of its buttons. Very recent tectonic movements as well as dissolution phenomena of its subsoil due to pressurized underground water have played an important role in the morphogenesis. Such conditions have resulted in a fast morphological evolution which a progressive lowering of the valley floor as well as peculiar morphological features which favour the existence of numerous pits caused by sudden collapses distributed in altitude and time

ln this paper we describe a stratigraphic column of the Cretaceous of the Montgrí. This description is based on several partial stratigraphic cross sections as well as on the lithological character of the different levels and their faunal content, specially megafossils

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

Starting from the discovery of a cheek-booth Dinotherium giganteum KAUP in the river Oñar in Gerona we can consider that the Miocene formations of La Selva expand up to this area

From several small stratigraphic sections, we have reconstituted the Liassic interval of the Girona Province (NE Spain). We have been able to identify paleontologically the Carixian (Jamesoni, Ibex, and perhaps, Davoei zones), the Lower Domerian (Stockesi zone), and the Middle Toarcian (possibily Variabilis zone, as well as Thouarsense and Insigne zones). The Lower Toarcian (Serpentinus zone) is represented by fossil remains no ‘in situ’. The lowest Toarcián (Tenuicos-tatum zone) as well as the Middle and Upper Domerian (Margaritatus and Spinatum zones respectively, are probably represented by stratigraphic gaps

En primer lugar se identifican las distintas rutas del Camí de Sant Jaume en la provincia de Girona con el objetivo de determinar cuáles han sido las principales rutas que los peregrinos han utilizado para su peregrinación hacia Santiago de Compostela dentro de la provincia de Girona. En segundo lugar se establecen los elementos que determinan que un itinerario concreto esté comprendido en el Camino de Santiago para lo cual se analizan las rutas y se buscan los componentes que tienen una relación directa con la peregrinación a Santiago de Compostela, bien por ser elementos descriptivos del Santo, bien por ser elementos que a lo largo de la historia se han atribuido a los peregrinos que peregrina a Santiago de Compostela. En tercer lugar se analiza el recorrido del Camí de Sant Jaume elegido por la Generalitat de Catalunya, se examinan los servicios que ofrece y las carencias o insuficiencias que posee. Finalmente se establece la confección de propuestas de mejora y las acciones pertinentes para corregir las debilidades que en su caso puedan tener estos itinerarios

Es descriu un aflorament volcànic localitzat a la rodalia del mas Ventós (el Port de la Selva), a la part central de la serra de Rodes, dins el Pirineu axial. Es tracta d’una xemeneia volcànica enclavada en granodiorites gneissificades. Els materials que la componen són basalts olivínics alcalins amb textura traquítica, bastant alterats, els quals queden colgats per un dipòsit col·luvial sense consolidar. Les dimensions de la xemeneia són difícils de determinar pel recobriment que presenta: supera els 70 m en direcció nord-nord-est a sud-sud-oest i és d’uns 35 m en la perpendicular a aquesta. Aquest aflorament va ser citat per Teixidor fa més d’ un segle, i no s’ha retrobat fins ara

En aquest treball es descriuen les característiques litològiques principals de tres afloraments volcànics inèdits que han estat localitzats al terme municipal de Roses. Es tracta de materials basàltics, similars als que s'associen a altres manifestacions efusives neògenes de la comarca de l'Alt Empordà

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

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

Es descriuen els afloraments volcànics de les comarques gironines, que segons la seva edat es poden subdividir en: manifestacions eruptives paleozoiques i afloraments relacionats amb el vulcanisme de l'era cenozoica

The origin and the primary features of the erosive earth pillar-like formations that develop in the Riera de Gaià (Barcelona) and in the Bernal de Yátor (Granada) are described. They are dynamic formations typical of areas subjected to strong water erosion

El projecte estudia la producció ecològica de planta aromàtica i medicinal com a alternativa a la producció de cereals en una de les parcel·les de Mas Teulera, situada al terme municipal de Lladó, a l’Alt Empordà, per millorar la rendibilitat econòmica de la finca. Es proposa la rotació de cultius de planta aromàtica i medicinal més adequada tenint en compte la seva adaptació en el medi, la sortida comercial més interessant i la compatibilitat del seu procés productiu amb les característiques tècniques de l’explotació. Es realitza a més, un avantprojecte sobre la transformació de la collita per a conèixer les característiques del procés d’assecat de les plantes necessari per obtenir un producte de qualitat i amb el format adequat per a la seva comercialització
