13. Processos metalogenéticos em ambientes de arco magmático tipo andino, caso de estudo: mineralizações da região dos Andes Patagônicos setentrionais do Chile / Metallogenic processes in andean volcanic arc setting, study case: mineralizations in the Chilean North-Patagonion Andes
In the Patagonian Andes region between 41 and 44° S extensive and continuous plutonic rocks of the North-Patagonian Batholith north segment are exposed. During their evolution most of the granitic rocks were emplaced in metamorphic rocks and other parts were emplaced in Late Jurassic-Berriasan volcanic rocks, Early Cretaceous sedimentary and volcanic rocks,

17. Condicionantes geoambientais no processo histórico da ocupação territorial do município de Guarulhos, Estado de São Paulo
The objective of this study is to examine the relationship between geoenvironmental parameters and the historical processes of land use and occupation of the Guarulhos municipal area, from the 16th century until present day. The city of Guarulhos, located in the Greater São Paulo Area, holds the second largest urban population in the State of São Paulo, es

18. Tafoflora deógena de depósitos provavelmente correlatos à formação Rio Claro, ocorrente no Município de Jaguariúna, SP
The Jaguariúna taphoflora occurs in Cenozoic sediment probably correlated or included in the Rio Claro Formation, outcropping at the left margin of the km 136,5 of the highway SP-340 (from Campinas to Mogi Mirim direction). This taphoflora is preserved as foliar impressions (parts and counterparts) covered by whitish film, on a massive variegated yellow-ora

19. EVOLUÇÃO TECTONOSSEDIMENTAR DA BACIA DOS PARECIS AMAZÔNIA
The Parecis basin is located in central-western Brazil, on the southwestern part of the Amazon craton, between the Rondônia and Guaporé fold belts. From west to east, the Parecis basin can be divided into three tectono-sedimentary domains: a tectonic low to the west, a central compartment characterized by a negative gravimetric anomaly, and a interior sag

21. Produção de mapas de vulnerabilidade de solos e aqüíferos à contaminação por metais pesados para o estado de Minas Gerais / Production of soils and aquifers vulnerability maps to heavy metals contamination for the State of Minas Gerais, Brazil
The study of environmental vulnerability to chemicals nowadays is an important tool to make decisions refering to the use, occupation and management of soils and aquifers. In humid tropical systems where the weathered mantle is depth and well developed, the soil reactivity becomes more important than its permeability. In this way, it is being proposed in thi

22. Caracterização tafonômica das concentrações fossilíferas da Formação Cape Melville, Grupo Moby Dick (Mioceno Inferior), Ilha Rei George, Antártica / Taphonomic characterization of fossil concentrations from the Cape Melville Formation, Moby Dick Group (Early Miocene), King Georg Island, Antactica
Works focusing on the taphonomy of fossil concentrations generated in glacial or periglacial environment are rare. In this context, the present dissertation carried out the taphonomic characterization of the fossil concentrations of the Cape Melville Formation, Moby Dick Group (Lower Miocene), King George Island, Antarctica, in order to elucidate the genesis
