This work analyses the spatial distribution of the Brazilian caves by using geoprocessing techniques and associating these caves to different thematic maps. According to the Brazilian Center for Research and Conservation of Caves (CECAV) database, there are 16,089 known caves in Brazil. The spatial analysis of these caves was performed by combining...

... integrating the cave locations with the geological map of Brazil, it was possible to see what types of rock they tend to occur associated with (Fig. 7). However, it was decided not to use this map to determine the number of caves that occur by each type of rock, because lithologies, unlike biomes and watersheds, are not always large areas. Rock units can occur as small bodies or layers; thus, in the adopted scale, these rocks could not be seen on the map. In other words, rock units ...
