Previous issue date: 2015-02-20 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico - CNPq / As praias de Cacimbinhas e do Madeiro est?o inseridas no litoral oriental do estado do Rio Grande do Norte, mais precisamente no munic?pio de Tibau do Sul. Diante dos indicativos de eros?o na costa deste munic?pio e dos processos costeiros atuantes nas praias, buscou-se, como objetivo geral desta pesquisa, compreender a evolu??o do ambiente deposicional de Cacimbinhas e do Madeiro, al?m de caracterizar os ambientes pret?ritos das praias por meio de an?lises sedimentol?gicas; identificar a idade dos sedimentos praiais por meio de data??o absoluta com aux?lio de t?cnicas utilizadas em estudos voltados para o per?odo Quatern?rio; e desvendar a evolu??o paleogeogr?fica das praias de Cacimbinhas e do Madeiro. Para isso, o estudo est? envolvendo pesquisa bibliogr?fica e de campo, ambas pautadas em trabalhos acad?micos, leis, conceitos e teorias concernentes ? geografia f?sica, geomorfologia do quatern?rio, geologia sedimentar e estratigrafia. Dessa forma, os procedimentos metodol?gicos foram subdivididos em tr?s etapas: Etapa pr?-campo: onde est?o sendo realizados os trabalhos de gabinete; Etapa campo: momento onde ser? realizada a aquisi??o das amostragens; e Etapa p?s-campo: onde ocorrer? a an?lise e integra??o dos dados processados adquiridos ao longo da pesquisa. Sendo assim, foram apresentados alguns resultados parciais de uma prospec??o preliminar realizada em dezembro de 2013, que teve por objetivo checar os dep?sitos sedimentares das praias e realizar uma breve caracteriza??o dos mesmos. Portanto, pode-se dizer, de maneira mais ampla, que estudos voltados para as ?reas costeiras s?o de grande import?ncia, uma vez que, em todo mundo, a maior parte dos grandes s?tios urbanos est?o assentados sob dep?sitos de idade quatern?ria e, nesse sentido, a conclus?o deste trabalho pretende contribuir para o conhecimento da din?mica sedimentar destas praias e, gest?o e planejamento desta ?rea que est? voltada, principalmente, para o turismo estrangeiro. / The Cacimbinha and Madeiro beaches are located in the eastern coast of Rio Grande do Norte
state, in the municipality of Tibau do Sul. Given the indicative of erosion in the coast of this
district and the coastal processes acting on the beaches, the global aim of this project is
comprehend the evolution of depositional environment on the Cacimbinha beach, moreover,
the project seeks to characterize deposits from the Cacimbinha and Madeiro beaches,
according to the geomorphologic compartments identified on these beaches; distinguish the
coastal features which possibly interact with the Cacimbinha beach; identify the potential
relationship between the sediments from the coastal features and the deposits from
Cacimbinha beach; understand which depositional processes that prevail at each facies
deposited on the beach; and identify the probable sedimentary environments and its energy of
deposition through of the materials recorded on the Cacimbinha beach. This study was based
on previous bibliographic and field research, both guided by academic works, laws, concepts
and theories concerning the physical geography, geomorphology of the quaternary,
sedimentary geology and stratigraphy. Thus, the methodology was divided in three steps: Prefield
step: office work was performed; Field step: Sampling of facies of sedimentation; PosField
step: analysis and integration of data obtained during the research period. Thus, the
results showed deposicional facies with distinguished energy in the relief compartments,
beach and terrace. After the sedimentary analysis and its interpretation linked to the
architecture of the mounted sections based on drilling, it became possible to trace the
evolutionary history of this stretch of beach. Therefore, it can be stated that studies performed
on coastal areas are of great importance, as long as, around the world, the most part of urban
zones are seated on deposits of quaternary age and, then this work improve the knowledge
regarding the sedimentary dynamics of this beach, becoming scientific support for
management and planning of this area which focus on, mainly, the foreign tourism
