TITLE:

SUMMARY:

The northern coast of the state of Rio Grande do Norte is classified as a mixed-energy tropical coast and presents a very intense coastal dynamic. Within this context is outstanding the presence of barrier island-spits system, which are sandy bodies parallel to the coastline, which isolate protected areas from the impact of the open sea. These bodies are restricted to the northern coast and are limited by two main fault systems, the Carnaubais and Afonso Bezerra systems. The barrier island-spits systems stand out for having different sedimentary deposits on their marine and terrestrial sides. In this perspective, the characterization and analysis of this system, having the knowledge about the processes that act in these environments and their sedimentary/stratigraphic configuration is of utmost importance for both environmental studies and reservoir analogues. The present study has as main objective the characterization of the tropical barrier island systems of the northern coast of the state, near the city of Macau/RN, with applications to petroleum reservoir analogs and the environment, focusing on their vertical sequence. The research includes data on grain size, gamma ray profile, calcium carbonate and organic matter content from 27 core samples of sedimentary material collected by the vibration method. The characterization and analysis of sedimentary deposits of current barrier island systems can be used as a tool for correlation with analogues to potiguar basin reservoirs, or other basins with similar genetic characteristics, as well as for understanding the environmental changes that occurred during the Quaternary.
