The municipality of Icapuí is located near the border with the state of Rio Grande do Norte, easternmost state of Ceará, and the study arca is located in the central arca of the coastal zone of the municipality, covering the beaches of Barrinha, Quitérias and Requenguela, being inserted within the Potiguar Basin. This work aims to map and characterize the Geoenvironmental Units of the region, based on the Resolution No. 01 of February 24, 2005, of the State Environmental Council (COEMA), as well as to analyze the context involving use and occupation Of the arca and the delimitation of the Technogenic Deposits of the arca. For this purpose, remote sensing and geoprocessing tools were used, fieldwork to verify and correct previously obtained data, as well as a survey and study of the elements that make up the region's geoenvironmental systems, such as geology, geomorphology, climatology, Oceanography, soil and vegetation. The presence of geomorphological features resulting from the interaction of these elements with sea levei variations during the Quaternary period allowed the identification of six Geoenvironmental Units: Pre-coastal Table, Cliffs (characterized by the top of the Potiguar Basin, Potengi Formation), Dunes, Marine Terraces, Lagunar Plain and beach, and for a better characterization of sedimentological analyzes of each one of the units covering the granulometry were canied out, CaCO3 content and identification of heavy minerais. Technogenic deposits were also classified according to Fanning & Fanning (1989) apud Peloggia (1998a), being the Barrinha Port and containment work defined as a reservoir built espolics, and the salinas and shrimp ponds as built dredged. The realization of this work allowed the elaboration of three cartographic products of the region: map of the local geology, the Geoenvironmental Units and the Technogenic Deposits, besides the elaboration of a Digital Terrain Model and three profiles.
