Abstract: | Angra dos Reis/Itaguai region of the state of Rio de Janeiro, Brazil, is a very problematic area due to the instability of
slope and landslides, due to geological and geomorphological conditions and to the significant and continuous human occupation
over favorable areas is prone to the triggering of landslides. The samples were analyzed by thermogravimetry (TG), derivative
thermogravimetry (DTG) and differential thermal analysis (DTA). This paper analyzes and characterizes the clay minerals and
presence of water, gravitational mass movements’ sites and compares it with sites where gravitational mass movements do not
occur. Indeed, this analysis also attempts to verify the presence of minerals. |
