PR2 GEOSSITIO Ambiente deposicional dos Quartzitos

PT - APPLICATION ROUTES GEOSITES PR2-MAC-ROUTE OF BREJO AND BANDO DOS SANTOS 52 - GEOSSITIO Quartzite depositional environment GPS - N 39 36.831 W 007 58.487 GEODESIC VERTICE Serra do Bando do Mação ALT 643 M The Geodesic Vertex of the Serra do Bando dos Santos corresponds to a spectacular panorama, being the 2nd highest point in the district of Santarém with 643 m, only surpassed by Serra de Aire (678 m). It is also worth mentioning that the 3rd highest point, Santarém district, is located in Mação (Serra do Bando do Codes - 624 m) To the Southeast you can see the Serra de S. Mamede (Castelo de Vide), the quartzitic crest of the Ródão (Portas do Ródão) and the Northeast to the Serra da Gardunha and, further down, on high visibility days, the Serra da Estrela . As we have already seen, the quartzite unit is organized in sequences with thinner layers at the base and thicker at the top, in addition to containing numerous fossil tracks and sedimentary figures. This quartzite ensemble can be interpreted as channeled deposits associated with environments of high energy coastal dynamics that developed close to the coastline. On the other hand, the occasional presence of millimeter horizons composed of red pelites between the sand strata suggests that they may reflect a drop in sea level and, eventually, deposition in an oxidizing environment.
