Between Lagos and Albufeira, the Algarve coast of southern Portugal is marked by outcrops of the lower Miocene Lagos-Portimão Formation (LPF) consisting of yellow sandstone and coarse skeletal-rhodolithic limestone. This contribution focuses on the rhodoliths, their paleoecology, taphonomy, and biological composition, in the Lagos Biocalcarenite, the lower member of the LPF. Special attention is paid...
The concept of geodiversity is extensively used in geoconservation and geoheritage contexts. Its cultural value, i.e. the value attributed by society to aspects of the abiotic natural environment because of its historical, emotional or community importance, is widely recognised. One important manifestation of the cultural value of geodiversity is the strong bond experienced by humans when interacting...
One key element defining the appearance of Lisbon is the whitish Cretaceous fossiliferous limestone locally known as “liós.” The liós is abundantly used as ornamental stone in Lisbon’s monuments and buildings. Ceramic tiles are also paramount in creating Lisbon’s character. Their ubiquitous presence, their colourful patterns and even the unique way they reflect sunlight make them inextricable from...
Abstract Extensive bivalve borings are described in detail for the first time from basalt rockgrounds in the North Atlantic volcanic islands of Macaronesia. They occur on a Middle Miocene rocky shore of a small islet of Porto Santo (Madeira Archipelago of Portugal), as well as on Plio-Pleistocene rocky shores on Santiago Island (Cape Verde). A basalt substrate is widely penetrated by clavate-shaped...
The use of rocky palaeoshore bioerosion analysis as a tool to solve stratigraphic and tectonic issues is beginning to bear fruits. The occurrence of an extensive intra-Miocene marine abrasion platform in southern Portugal at Oura (Albufeira) has been identified on the basis of bioerosion trace fossils analysis. The observed ichnodiversity is rather low, with bivalve boring Gastrochaenolites being...
