Aportaciones al conocimiento de la geología de Bac Grillera (prepirineo, Girona)

The Bac Grillera nappe (Prepirenean of Girona) shows a stratigraphic section composed of two unconformi ty-bounded units. The lower unit is composed by rethian (marly limestones) and liassic (brechoid marly limestones and limestones). The upper unit (sandstones and marly limestones) belongs to the upper Cretaceous (Campanian)

Les Gavarres: la personalitat geológica

Descripció litològica i morfològica del Massís de les Gavarres

Els termenals de Solius (Santa Cristina d'Aro, Baix Empordà) de l'any 916 al 1057

The boundaries of Solius (Santa Cristina d'Aro, Baix Empordà) from 916 to 1057. Basing its study on seven documentsfrom the years 916 to 1057, the place names are described and located on two maps marking the boundaries of the district of Solius (Santa Cristina d'Aro, Baix Empordà). There is an attempt to show, among these facts, that there actually existed three different districts of Solius, which we call here Solius Whole, Solius Maritime and Solius Continental; there is also reference made to the names of the different owners as well as the border relations with the neighbouring villages

La Pedralta, un ejemplo de patrimonio geológico de Girona

Pedralta is a very large rocking stone shaped in monzonitic granite. Its volume and weight are approximately 34 m3 and 90 Tm. The fall of such block has supposed the loss of a worthy geotipe

Costa Brava central y meridional

Esta excursión, centrada en el extremo septentrional de la costa mediterránea de la península ibérica, tiene como objetivo fundamental la visita de algunos elementos geológicos puntuales que destacan por su especial interés, y que constituyen parte del patrimonio natural de esta zona. Además, a lo largo del itinerario se ofrece una visión general de la constitución geológica de este sector costero

El campo volcánico catalán

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

Aportaciones al conocimiento del Cretácico del macizo del Montgrí (Girona)

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 characterof the different levels and their faunal content, specially megafossils

L'aflorament volcànic del mas Ventós (el Port de la Selva, Alt Empordà)

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

Aportacions al coneixement del vulcanisme neogen de l'Alt Empordà: tres afloraments volcànics inèdits al terme municipal de Roses

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, similarsals que s'associen a altres manifestacions efusives neògenes de la comarca de l'Alt Empordà

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

Morfolitología de las terrazas del Ter en Girona

It is a contribution to the study of the terraces of the river Ter along its mid-course in the town of Girona, since that is the last speace where it is still possible to observe four of these terraces with clear characteristics of climatical deposition. Itsmorphological peculiarities are described as well as the morphometrical and lithological parameters of its pebbles. These terraces are compared with others which have been studied in other areas of the regions and conclusions are drawn concerning deposition, source àrea and chronology
