Imageamento Digital de Paleocavernas Colapsadas na Bacia Potiguar (Rn/Ce)

The Ground Penetrating Radar (GPR) images the subsur-face with submetre resolution. GPR profiles was conduc-ted along an outcrop of Jandaíra Formation (Potiguar Basin) in order to test the viability of this imaging method applied to Limestone tufas in collapsed paleocave. The GPR 2D data was acquired along the entire outcrop, and allowed well correlations between reflector’s pattern and tufas/speleothems in outcrop. The identification of (paleo-cavernas colapsadas) was made both by analysis of reflectors associated with tufas and by contact between the cave base and the roof collapsed.
