Considerações morfo-estruturais ao largo da Ponta do Pai Vitório, Búzios, RJ

Abstract

The understanding of the mechanisms e causes of the tectonic movements has much worried the human race, not only in concern of natural catastrophic events, as well as the protection and maintenance of engineering structures and bottom and sub-bottom morphology in many places of the earth´s crust. This present work aims to illustrate structural features originated from tectonic movements, focusing more in the recent tectonic movements examples. The area of this present work is located very close to the prolific Campos Basin in Rio de Janeiro state, more precisely on the shallow platform area offshore of Ponta do Pai Vitório in Búzios-RJ. The geophysical prospection was done using a sub-bottom profiler from Edgetech, the Geostar SB-216S with the intention of identification and mapping the structural features originated by recent tectonic movements. Seismic profiles dip (parallel) and strike (perpendicular) of the Pai Vitório´s fault (Heilbron, 1982) were obtained and analised. In this present work is only parcial results which are well satisfactory in the exemplification of the structural features from recent tectonic movements.
