An underground deposit of granite in the municipality of Tracuateua, in the Brazilian state of Pará, is being quarried by the Santa Mônica Mining Company for the extraction of raw material for the local construction sector. This deposit is exploited in traditional fashion, by using dynamite to dislodge the rock. This activity appears to have caused cracks in buildings in the region, as well as degrading features of its ground, landscape, and relief, and even contaminating one of the the principal local rivers. In the present study, the Ground Penetrating Radar (GPR) tool was used to evaluate the structure of the subsurface and possible environmental impacts caused by quarrying with dynamite at the study site.
