Identifying soil horizons transitions for ground-truthing and interpreting ground penetrating radar (GPR) imagery of Planosols. Author(s): NASCIMENTO, C. W. R. do; CEDDIA, M. B.; VASQUES, G. M.; RODRIGUES, H. M.; MARTINS, S. S.; OLIVEIRA, R. P. de; TAVARES, S. R. de L. The Ground Penetrating Radar (GPR) has potential to characterize soils both vertically and horizontally. The effectiveness of using GPR relies on the interpretation of soil targets in the radargrams.... ... Repository: BDPA Publication year: 2023
Gamma-ray spectrometry for distinguishing acid and basic rocks of the serra geral formation, in the serra gaúcha wine region, Brazil. Author(s): MODENA, R. C. C.; HOFF, R.; FARIAS, A. R.; VIEL, J. A.; COELHO, O. G. W. The gamma-ray spectrometric research has allowed for observation of the distribution of radioactive elements such as K, U and Th for recognizing the radioactive signatures of different rock types. The... ... Repository: BDPA Publication year: 2016
