PRELIMINARY INVENTORY AND CONSERVATION CONDITIONS OF SPELEOTEMS FROM GRUTA DA SERRA DAS COBRAS, SANTA QUITÉRIA, CEARÁ, BRAZIL

Abstract

Natural underground cavities are environments composed of unique characteristics that house a great complexity of geological formations and lush scenery. The underground environment is considered a true treasure for science and humanity. The main objective of this research is to identify and classify the different types of speleothems found in Gruta das Cobras located in the municipality of Santa Quitéria/CE, also highlighting the risks that these structures face in terms of conservation. The materials and methods consisted of bibliographical research, fieldwork, photographic records and analysis and interpretation of information obtained at all stages. In general, the most common speleothem formation present in the study area is of the stalactite and stalagmite type. Speleothems of the column type, Bridal cake and Boxwork type were recorded inside the cave, complex formations that take millions of years to form and which are currently being impacted by the tourism sector, with no regulation or inspection. Impacts on structures, graffiti and breakage of speleothems were identified. In this way, it is concluded that further studies on the site are essential, as well as a preservation intervention by the competent public bodies.
