Castro de Guifões: elementos para a reconstituição paleogeográfica e compreensã...

Documented since the middle of the 1st millennium BC, the occupation of Castro de Guifões extended to the ancient Leça estuary. The GUIFARQ Research Project has sought to clarify the importance of the site's relationship with the river and the Atlantic, attested by archaeological materials and described in historiographic sources. A research program at the intersection of Archaeology and Fluvial Geomorphology c...

Spatial variations in sediment production and surface transformations in subtro...

Several compositional features of sedimentary deposits can be used to reconstruct environmental conditions of source areas. In this research, bulk X-ray diffraction mineralogy, heavy and clay mineral assemblages and geochemistry obtained for modern deposits of the Cunene River and its tributaries Caculuvar-Mucope are integrated with geological/geomorphological characteristics of respective catchment areas to ev...

A indústria lítica da Zona Industrial de Bouro (Gandra, Esposende, NW de Portug...

The archaeological monitoring carried out during the construction of an industrial pavilion, in Bouro, Esposende (NW Portugal), allowed the collection of over two hundred knapped stone artefacts made from quartzite pebbles. The most significant assemblage, with tools belonging to the Acheulean technocomplex (handaxes and unifaces), is associated with a marine terrace at 15-20 m a.s.l.. Considering OSL dating ob...

Caraterização geomorfológica dos inselbergs do setor Malema-Ribáuè da Província...

This study aims to understand the relationship between the geological and morphological characteristics of the inselbergs located in the Ribáuè-Malema sector of Nampula (Mozambique). The detailed characterization of this particular type of landscape will contribute to develop further studies focused in geoheritage and environmental conservation topics. The study area comprises part of the Malema, Ribáué and Lal...

Controle litológico sobre índices de meteorização química: um caso de estudo co...

Different compositional features of sedimentary units have been used to evaluate the intensity of chemical weathering. In this work we used the geochemistry and clay mineralogy of a set of present-day sediments collected in the lithologically and geomorphologically heterogenous Caculuvar- Mucope fluvial system to investigate the processes that influence weathering proxies. Weathering proxies measured in deposit...
