Coral reefs are habitats with high animal and mineral diversity subject to both climate change anthropogenic impacts. This article presents novel relevant data on the Seixas coral reef environment's geological, sedimentological, mineralogical, biotic aspects in Paraíba State, northeastern Brazil. The aim of this study is evaluate processes formation species urban coastal environments Brazil using a multi-proxy approach. Materials methods employed analyze abiotic include (a) bathymetric survey, (b) collection granulometric data, (c) geological stratigraphic determination, (d) identification species. Mineralogical slide results reveal that Reef recent biogenic coral-algal carbonate associated coastline evolution, sedimentation, changes occurred alongside sea-level rise (Holocene-Quaternary period). indicate benthic organism settlement consolidated arenite base, fauna undergoing continuous succession processes. It can be concluded highly vulnerable due material its comprises subsectors (fore reef) others low (reef top), which affected by natural factors. Studies nature contribute understanding evolution reefs, as their proximity continent makes them more vulnerable, they experience direct physical impacts from fishing tourist activities.
