| Summary: | Quantitative assessment of geological sites has been demonstrated as a consistent tool in order to delineate geoconservation strategies, especially for large areas with scarce resources. The working area is located in a vulnerable
region in north-eastern Brazil characterised by low socioeconomic conditions. This area comprises an assemblage of 52
geological sites (geosites and geodiversity sites) representing the geodynamic evolution of the Ceará Central Domain,
one of the oldest tectonic terranes in Brazil. In this perspective, this work aimed to identify priority sites for geoconservation actions. All geological sites were evaluated by a quantitative assessment concerning the scientific value, the
degradation risk, the educational and touristic potential uses and the protection priorities. The assessments were performed by the method available on the GEOSSIT platform developed by Brazilian Geological Survey. Results indicate
geological sites with high scientific value, predominance of geosites with moderate degradation risk and medium values
for educational and touristic potential uses. Three sorted lists were defined considering only geological sites with high
scientific value (geosites) and relevant potential uses. At the end, four priority areas were delineated for a detailed geoconservation plan in the centre-north portion of Ceará Central Domain |
