ARAÚJO, M. A. - Protection and Conservation of Sampaio Area (Labruge, Vila do Conde, North of Portugal), in "Littoral/94" proceedings, Associação Eurocoast-Portugal, IHRH (Instituto de Hidráulica e Recursos Hídricos da Univ. do Porto) e ICN (Instituto de Conservação da Natureza), Vol. II, 1994, p. 865-877.
ABSTRACT
Sampaio's beach, located 15 km North of Porto, has many points of interest. There is a fossil wave cut notch and a marine deposit, hanging at 9 meters high. Nearby we can see a deposit of the same age (probably last interglacial), lying at 5 meters. The difference in the altitudes of the two deposits could be explained by a neotectonic effect, as all the cliffs that enclose Sampaio's beach are structurally controlled. Over the 5 meters marine deposit we find a complex würmian sequence, with two solifluxive deposits and an aeolian deposit between them. The association of this geomorphological features with a very rare archaeological site makes us emphasise the need of protecting this place. It is a very demanded beach, so, its protection must be done with the help of the concerned people. We are co-operating with Vila do Conde City Council for the preservation of this area and for environmental education of their students.
