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

Several marine deposits in the southern Costa Brava shoreline have been studied. They appear at different heights above and below the present sea level. Three groups are defined in relation to their origin: conglomerate levels at the bottom of the cliffs, not-cementedemerged beaches and cemented submerged beaches. The age of the emerged beaches has been accurately determined by means of the ceramic content and radiocarbon dating. Chronological succession of the deposits and their stratigraphic and paleontological characteristics allow to define a sequence of the sea level changes during the latest stages of the versiliane transgression in the studied area

Two unknown volcanic outcrops in the Alt Emporda (Girona) are described in this paper . We present their exact situation and a description of their occurrence and their mineralogical and petrological characteristics. Bothhave been classified as alkali-olivine basalts and they probably extruded during the Neogen period

Es descriu la seqüència de materials travessats en un sondatge mecà nic realitzat al cim del turó de Santa Maria de Roses. Es posa de manifest que aquest alt topogrà fic és constituït per una successió de capes de graves amb intercalacions de nivells argilosos i arenosos. La capa més superficial és de l'holocè superior, mentre que la resta pertany al pleistocè i, segurament, ai miocè superior
