Morfogénesis del valle de Sant Miquel de Campmajor

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

Previsió d'impactes en el medi físic, derivats de l'explotació de les formacions geològiques d'interés per a la producció d'àrids, a la zona del curs mitjà del Riu Fluvià (La Garrotxa)

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

Morfogènesi de pilars de terra (earth Pillars, hoodoos). Exemples de la Riera de Gaià (Vallès Occidental, Barcelona) i del Bernal de Yátor (Las Alpujarras, Granada)

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

Unitats litològiques d'interès per a la producció d'àrids a l'àrea del curs mitjà del riu Fluvià (la Garrotxa)

Pleistocene and Quaternary sediments adjacent to the medium course of the Fluvià river are a source of aggregate in the Garrotxa. Four lithological units can be used directly, or with a minimal processing as coarse aggregate. They have been mapped in detail at the 1:5.000 escale. The stratigraphic analysis have made possible the four units to be ordered in relation to their suitibility for usage as aggregate. From high to low relative quality they are: the basaltic flow, fluviatile deposits, plio-quaternary conglomerates, and glacis deposits

El paleozoic del massís de Begur (Girona)

The Paleozoic materials of Massís de Begur are described from a stratigraphical point of view. We distinguish two units: the lower one, present phillites with carbonate layers ofcambro-ordovician age. The upper one is composed by volcanic rocks, carbonate schistsand black slates, bring from caradocian and ashgillian age

El paleogen del massís de Begur (Girona)

Stratigraphic series concerning the paleogenic materials of the 'Massis de Begur' are described. We note the presence of some diferences between its northem and westem margins

Possibles materials amb destinació a obres portuàries a la Costa Brava (Girona)

The metodology used in the research of materials destinated to port constructions in the Costa Brava is described. This metodology follows a set of work steps. The first three allow to do a selection of the stone quarries that exist in the zone. The other steps consists in studing the materials and the characteristics of the chosen quarries and the zones closed to them, as to order them according to their utility in port constmctions. Finally, the main results obtained are explained

Aplicación de un modelo de mezcla total en acuífero cárstico

Por el fondo de un valle de la provincia de Girona mana un conjunto de surgencias cuyo caudal total anual se acercaa medio centenar de hectómetros cúbicos. Controlando no solo la cantidad de agua de salida sino también su calidad desde el punto de vista de su contenido en tritio y a partir de un modelo conceptual de mezcla uniforme de las aguas de recarga, ya com probado en otros sistemas, se acota la cadencia de participación en las surgencias de las distintas recargas anuales, as como el tiempo de renovación del volumen de agua del sistema hidrogeológico

Principales características geoambientales en la región del alto Fluvià (Gerona)

This study is about the main characteristics of a large area in the province of Girona, the utilization of which has been historically poor, basically due to gecsnorphological causes. The analysis has been made considering the possibilities -both positive and negative - that the geological medium offers by appropiate use of the area, bearing in mind the possible impacts that these uses could have on the medium. The conclusions drawn from this study are shown in a series of maps

Sant Julià de Ramis y Puig Rom: dos ejemplos de yacimientos con armamento y equipamiento militar visigodo en el noreste peninsular

We present in this work a couple of weapons and objects related to the military equipment of early VIII century from two sites on Girona's province: the castellum of Sant Julià de Ramis (in the municipality of the same name), and the fort of Puig Rom (in Roses). The comparation of these materials has permitted to recompose a quite complete panoply with various types of knives and daggers, shield-handles, axes, spearheads and javelinheads, tips (regatones), arrowheads, belt-buckles and some buckles and horse harness elements

Composición y estructura de las comunidades de algas bentónicas de ambientes portuarios: El puerto de Blanes

The species composition and the structure of the harbour communities of Enteromorpha copmpressa, Corallina elongata and the internal communities in Blanes harbour (Girona, Spain), have been studied by means of descriptive and analytical data. All the quantitative parameters studied show a decrease of diversity in the more superficial stations of the mouth of the harbour, and also an increasing diversity and a drastic decreasing of the reproduction indices at the more polluted stations
