It contains in general some geographical and geological data, documented by maps, sketches and photographs. In the initial stage the coastal plain represents a marine ingression, caused by faulting. This ingression penetrated the valleys of a not yet determinated geological landscape. Ended the movement of deeping by faulting begins the epirogenic ascension and building of the barriers and beach ridges. An intensive sedimentation caused the lagoons and bays obstruction. This work refers mainly to t33 he sedimentary formations and the coastal plains is classified in the following way for the study in consideration to the... |
