Stratigraphy and sedimentology of the Hamill Group in the northern Selkirk Mountains, British Columbia : evidence for latest Proterozoic - Early Cambrian extension tectonism
The Yaracuy basin is a tectonic depression within an echelon stepover in the Bocono-Moron-El Pilar fault system. This basin is interpreted as a pull-apart basin formed by right-lateral offset along this fault system. The right-lateral offset
In some restricted sectors of the Brazilian coast, it has been possible to demonstrate the role played by the vertical tectonic movements in shifting Quaternary shorelines. Within Todos os Santos Bay, State of Bahia, located in the Reconcavo graben
-squares fit for 73 samples suggest little or no overall rotation, despite the severe late Quaternary tectonic activity demonstrated by the intense deformation of these strata.
. The different raised erosional features indicate independent vertical tectonic movement of the three islands, predating the formation of the raised reef. The accordance and horizontality of the raised reef indicates stability of the islands, since the last
and younger surfaces are developed mostly on Mesozoic and Cenozoic rocks, but more widely within the limits of the Andes zone. Tectonic uplift amplitudes are defined by measurements of planation surfaces distortions, shown at the applied map with isobases
. These deposits suggest that a significant amount of postglacial isostatic and (or) tectonic deformation has occurred in the Puget lowland since deglaciation.
