| Resumo | |
The interest in geoparks in Brazil began after the inclusion of the Araripe Geopark into the Global Geopark Network (GGN) in 2006. After that, several areas within Brazil were proposed as potential geoparks, two of which were then formalized-the Quadrilatero Ferrifero (Minas Gerais) and Bodoquena-Pantanal (Mato Grosso do Sul), and formal applications were submitted to GGN in 2010 but not accepted. In spite of the relevance in the geology and paleontology of both areas, the refusals were due to being only a project and not an actual functioning structured geopark yet working. No kind of inventory or quantification of the geological sites was carried out to both of the proposed geoparks. Furthermore, the purpose of the present work is to present an inventory of the sites of the area proposed for the Geopark Bodoquena-Pantanal (GBP) in an effort to demonstrate the significance of the geological heritage of the area. The area of the GBP includes Ediacaran animal fossils, which provide information about the geological record just before the Cambrian Explosion. This record created international interest in the area, together with sections with that record of global changes that characterized the end of the Neoproterozoic Eon, such as the iron formations of the Urucum Massif (Rapitan type) and Marinoan glacial sediments and limestone (Tamengo Formation). The present inventory was compiled by the GEOSSIT platform of the Geological Survey of Brazil (CPRM), which is based on the method of Brilha (2016), with modifications. The 51 sites investigated were distributed among 6 geological frameworks, defined to represent the geological history of the region, and 26 sites were considered as geosites, of which 12 present international relevance, specifically the sites of Corumba Group, due to the importance for the investigation of the Ediacaran period. The inventory and its numerical result show the scientific importance of the area, as already recognized by international meetings and publications on the geology, and is useful to future plan and revision of the proposed geopark.
