RESUMO:

The Potiguar coastal has various geomorphological features such as dunes, beaches, lagoons and cliffs that make up the Rio Grande do Norte geodiversity. Sea cliffs are important indicators of the environmental changes that occur in the Quaternary and for the reason they are natural monuments, they are the purpose of this study. Considering this, the overall aim is to produce a typological classification of the cliffs of Rio Grande do Norte. The specific aims sought to: investigate the existing classification on the sea cliffs of RN to further detail its main characteristics; read up the stages of the geomorphological evolution of the cliffs through literature review; classify the cliffs according to geological basis criteria as lithostratigraphic unit and influence of neotectonics; categorize the sea cliffs according to geomorphological criteria; classify the sea cliffs according to climatic conditions and vegetation cover and identify the values of geodiversity. The justification for this research is based on the conclusion that the sea cliffs are landscape elements of great scenic beauty, but paradoxically, they have great environmental fragility, due to their genetic, stratigraphic and morphological characteristics. The occupation of the Potiguar coastal zone, comparable to other Brazilian states, has been occurring in a way that does not respect the limits defined by the resolutions of the National Environment Council, standardized in 2002, in which defines the use and occupation of coastal areas, particularly in sea cliffs with slope greater than 45 °.Some work has already been done on the sea cliffs of Rio Grande do Norte by researchers who performed descriptions of environmental conditions and reported some problems related to disordered use and occupation. The social relevance of this research lies in the identification of the environmental situation of the sea cliffs that are landscape inheritances, according to the perspective of Aziz Nacib Ab’Saber that protects the marks of physiographic and biological processes and collective heritage of traditional communities and the Potiguar people. The adopted landscape concept is based on the reflections of Georges Bertrand and Carlos Augusto de Figueiredo Monteiro. The qualitative methodology seeks to contemplate, according to the hypothesis, the classification of potiguar sea cliffs according to their natural characteristics and geodiversity services.The methodological paths were divided into stages and the first was the data collection on the sea cliffs, in particular of the RN. The second stage included the execution of field research and the third stage was the preparation of cartographic material. Preliminary results point to different sea cliff typologies related to the source material (Barriers and Post Barriers); vegetation cover (vegetated and non-vegetated) and slope morphology, even if they were made from the same parent material. Related goods and services were partly identified, as well as major environmental issues affecting the geodiversity of the cliffs.
