• Abstract

  The combination of different geochronological methods associated to supergene minerals provides advances in the paleoclimate studies and landscape evolution rates. Thus, the aim of this work is to study the geomorphological evolution in the southeast of the Goiás State, between the cities of Caldas Novas and Rio Quente, using two geochronological methods, 40Ar/39Ar in manganese oxides and…

• Abstract

  The proposal aims to study the geological history of the Barreiras Formation in SE Brazil, and it has three objectives: 1. To bracket the history of weathering, deposition and iron-cementation of the Barreiras Formation; 2. To investigate the paleo-exposure history of the Barreiras Formation sediments and to determine whether goethite-cementation occurred mainly while sediments were expos…

• Abstract

  Erosion processes are essential to understanding the evolution of continental landscape. The action of these processes results in products that are the basis for the development of human activities, so that all available tools should be used in their evaluation. In this context, this research intends to conduct the evaluation and comparison of rates of erosion and sediment transport and i…

• Abstract

  Red mud is a waste generated by the extraction of aluminum from bauxite by the Bayer process. The amount of red mud produced is very large and requires a wide area for disposal. Although not classified as a hazardous waste, red mud has the potential to cause contamination of surface water and groundwater and can also cause caustic rainfalls, reaching the vegetation and animals in neighbor…
