1. Local geological sections and regional stratigraphy based on physical geology and chemical stratigraphy of the Serra Geral Group from Araraquara to Avaré, SP
ABSTRACT: From Araraquara to Avaré, in the Serra Geral Group outcropping area, 22 detailed geological sections were elaborated. The stratigraphic relationships and the chemical analysis allowed the identification of seven [P2O5] basalt classes, all of them pertaining to the Pitanga type, showing a consistent stacking order across the studied region. Thus, e

2. Nature et propriétés de l'horizon diagnostic de Latosols du Plateau Central brésilien.
The Latosols correspond to about 40% of the Brazilian Central Plateau. They are characterized by low activity clay, little horizon differentiation, a weak macrostructure and a strong microgranular structure resulting in microaggregates 50 to 300um in size. Ten Latosols (L) were selected along a 350-km long regional toposequence across the South American Surf

3. Evolução estrutural das zonas de cisalhamento dúcteis na porção centro-leste do domínio da Zona Transversal na Província Borborema / Structural evolution of ductil shear zones on Central Eastern segment of transversal zone domain on Borborema Province
A área estudada está inserida no Domínio Transversal da Província Borborema. As unidades litoestratigráficas que compõem o embasamento paleoproterozócio (riaciano) são representadas por rochas ortoderivadas dos Complexos Salgadinho e Cabaceiras. Esses complexos foram individualizados de acordo com as suas diferenças composicionais, texturais e/ou ge

4. Análise e avaliação dos problemas existentes na fachada de arenito do Museu Júlio de Castilhos, Porto Alegre, RS
The Júlio de Castilhos museum of Porto Alegre, formerly used as residence, was built in 1877 by a military engineer Catão Roxo. This building is one of the few examples of urban architecture from the last part of the nineteenth century. Its façade is covered by arenitic and granitic rocks quarried near the city. The covering shows the effects of weatherin

5. Caracterização geologica e geofisica da estrutura de impacto Domo de Vargeão, SC / Geologic and geophysical characterization of Vargeão Dome impact structure, SC
O Domo de Vargeão (SC), com 12,4km de diâmetro, é uma estrutura de impacto do tipo complexa parcialmente erodida, formada sobre os derrames vulcânicos da Formação Serra Geral, na bacia do Paraná. Em seu interior afloram, de forma anômala, arenitos atribuídos ás formações Botucatu e Pirambóia, normalmente situados a cerca de 1km abaixo da superf�

6. Environmental characterization and land-use condition of the landscape of São Félix do Araguaia municipality / Caracterização ambiental e condição do uso da terra da paisagem do município de São Félix do Araguaia MT
There is an increase need for remote sensing data and associated analysis techniques in detecting and monitoring landscape change, particularly for resource management and planning. Information derived from remote sensing spatial data landscape has often been used to assist in the formulation of policies and provide insight into land-use patterns. To underst

7. Geology of the Camboriú Complex (SC) / Geologia do Complexo Camboriú (SC)
The anatectic origin evidenced by known macrostructures in migmatites of the Camboriú Complex is supported by petrographical, geochemical and isotopic data, with partial melting under compressional regimen being suggested by the large amount of leucosome bodies at low-pressure sites represented by interboudins and dilation surfaces. Despite the continental

9. Evolução estrutural brasiliana da Província Borborema na região de Campina Grande, (PB) / Brasilian structural evolution of Borborema Province in the Campina Grande region (PB)
The systematic mapping of Campina Grande sheet (1:100.000) is very important to understand the structural and geochronological relations between different terranes of the Transversal Zone, Borborema Province (NE Brazil). The mapped area is an excellent natural laboratory to apply classical and modern techniques of structural geology for the study of mechanis

12. DEFINITION OF THE ENVIRONMENTAL UNITS IN HIDROGRAPHIC BASIN OF THE ITU RIVER W/RS / DEFINIÇÃO DE UNIDADES GEOAMBIENTAIS NA BACIA HIDROGRÁFICA DO RIO ITU OESTE DO RS
The study of the environment, knowing its resources and frailties, has been the work of the Laboratório de Geologia Ambiental (Environmental Geology Laboratory) (LAGEOLAM) UFSM during the last 10 years. The West-southwestern region of Rio Grande do Sul State represents an area of high environmental degradation, which is linked to accelerated erosion,
