Conservation of geosites as a tool to protect geoheritage: the inventory of Ceará Central Domain, Borborema Province - NE/Brazil.

The Ceará Central Domain, in the northern Borborema Province/NE Brazil, encompasses important geological records (geosites) which allow understanding a relevant period of the Earth's evolution, mainly associated to Neoproterozoic Brazilian/Pan-African Cycle and West Gondwana amalgamation, besides Neoarchean to Ordovician records. The presented geoheritage inventory aims to characterise the geosites with scientific relevance of Ceará Central Domain. By applying a method for large areas, the final selection resulted in eight geological frameworks represented by 52 geosites documented in a single database. This is the first step for a geoconservation strategy based on systematic inventories, statutory protection, geoethical behaviour and awareness about scientific, educational and/or cultural relevance of geosites.

Terrestrial impact structures as geoheritage: an assessment method of their scientific value and its application to Brazil.

Terrestrial impact structures are geological and geomorphological features with particular importance to understand the history and evolution of the planet. Impact structures are scattered around the world but in many countries these features are under threat, essentially due to anthropic factors. Impact structures with higher scientific value should be considered as geological heritage and, consequently, be subjected to geoconservation strategies. In order to select the most important impact structures to be properly conserved and managed, this paper proposes a quantitative assessment method of the scientific value of these structures. The eight Brazilian impact structures were used to test this method that has the potential to be applied to any geological context in any country. The structures known as Araguainha Dome-MT and Serra da Cangalha-TO reached a higher scientific value, which justifies the need to develop geoconservation strategies and a proper management.
