Geoconservação em patrimônios espeleológicos da Amazônia: proposta de planejamento ambiental para a província espeleológica Altamira-Itaituba (PA)

Abstract

The Amazon region is rich in geomorphological features as result of systemic interaction of nature elements, we can point out the speleological patrimony. The Speleology is an area of study that is dedicated to investigating the nature, genesis and formation processes of natural underground cavities (which include different denominations such as caves, shelters, etc..) and their related features, including even the biological. As an example, this research shows the Altamira-Itaituba Speleological Province (Pará State), located in the contact strip of that following geologic domains: Amazonas Sedimentary Basin and of basement of Xingu Complex. The geological structure is sandstones of Maecuru Formation and shale of Curuá Formation. This research is developed from the geoecologic analysis of the landscape of the Speleological Province, though a systemic method. The lack of protected areas in the Province detaches an important concern, since these environments are configured by landforms developed in siliciclastic rocks (pseudocarste). Considering that the Speleology is a multiple sense activity (scientific, sports, tourism and cultural), it is necessary to propose an environmental plan combined with the concept of geoconservation. This is a contribution to the speleological research and karst geomorphology in no carbonatic rocks, broadening and deepening the studies focused on the conservation of geological heritage in Amazon
