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. Genesis and Classification of Soils from Subtropical Mountain Regions of Southern Brazil
ABSTRACT Soils formed in high mountainous regions in southern Brazil are characterized by great accumulation of organic matter (OM) in the surface horizons and variation in the degree of development. We hypothesized that soil properties and genesis are influenced by the interaction of parent materials and climate factors, which differ depending on the locati

3. Análise da água e das condições ambientais da bacia hidrográfica do Ribeirão das Pedras, Quirinópolis/GO / Analysis of water and environmental conditions on Ribeirão das Pedras basin, Quirinópolis/GO
This research was based on the perspective to understand the influence of land use in the physical and chemical indicators of water quality of the watershed of Ribeirão das Pedras - Quirinópolis / GO, which is the main source of public water supply in this city. As this area is occupied by domesticated animals raised in an agricultural setting to produce c

5. Micorriza arbuscular: um bioindicador da fertilidade dos solos e da distribuição de árvores no bioma cerrado.
RESUMO: A grande variedade de fitofisionomias existentes no Bioma Cerrado tem sido associada a diferentes fatores ambientais como clima, relevo, geologia, entre outros. O fator solo exerce influência fundamental nessa diversidade ambiental. As suas características químicas, físico-hídricas e biológicas formam um complexo de inter-relações, muitas vez

6. Visualização volumétrica aplicada às Geociências
This paper is on volume visualization of spatial data. It aims at showing new possibilities to visualize three-dimensional phenomena such as geology, soils, geophysics, seismic and the like. The use of volumes in the evaluation processes allows one to visualize and to explore the phenomenon as a continuous body in space, thus incorporating the third dimensio

7. 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

8. Atividade e diversidade catabólica da biomassa microbiana do solo alterada pelo uso da terra / Effects of soil land use on microbial activity and catabolic diversity
The increasing demand for food creates environmental problems, mainly due to the removal of native vegetation cover for agriculture expansion in Brazil. These changes in land use leads to changes in the soil organic matter dynamics. The vegetation type also affects the soil biota and, therefore, its change causes modifications in the microbial biomass, as sh

9. Metalogênese do depósito de cobre Cerro dos Martins, RS: revisão e geoquímica isotópica de SR, O e C-
This paper presents the geology, chemical data, Pb-Pb zircon ages, sulfur, carbon, oxygen, strontium isotopes and fluid inclusions of Cerro dos Martins copper deposit. The deposit is hosted by the Neoproterozoic volcano-sedimentary sequence of the Camaquã Basin in the Rio Grande do Sul Shield, southern Brazil. The ores consist of a set of Cu-sulfide NW-tren

10. ANÁLISE QUÍMICA MULTI-ELEMENTAR DE AMOSTRAS DE ÁGUA TRATADA E ASPECTOS DE SAÚDE PÚBLICA DE MUNICÍPIOS DA MESORREGIÃO SUL DE GOIÁS
Water, essential for life, has a direct influence on health, quality of life and development of mankind. However, due to natural and human causes, water may suffer contamination from various species, especially for chemical elements. Thus, this paper appears the results of a study of multi-elemental chemical analysis of samples of treated water collected in

11. Relação solo-relevo-substrato geológico na planíce costeira de Bertioga (SP) / Soil-relief-geologic substract relationship on the coastal plain of Bertioga (SP)
Knowledge of the chronology, relief, geology and soils in sedimentary coastal environments is relevant for their interpretation, reconstitution and conservation. In Bertioga, São Paulo State Brazil, several sections of the Pleistocene and Holocene morphostratigraphic costal plain units are preserved in the landscape. This thesis seeks the perception of the

12. Geology of high pressure granulites of Carvalhos Klippe, southern Brasília Belt / Geologia dos granulitos de alta pressão da Klippe Carvalhos, extensão sul da Faixa Brasília
At the top of Andrelândia Nappes System, southern border of São Francisco craton, occur nappes formed dominantly by metasedimentary rocks with subordinated metabasics and metaultramafics which record metamorphism of high pressure granulite facies in the Ediacaran. These nappes are Três Pontas - Varginha, Pouso Alto and Klippen Airuoca and Carvalhos. In Ca
