1. Pedological Heterogeneity of Soils Developed from Lithologies of the Pirambóia, Sanga-do-Cabral, and Guará Geological Formations in Southern Brazil
ABSTRACT The source material is one of the factors that most influence soil genesis and the mainly responsible for the nature, composition, and behavior of the soil. Given the geological complexity of the Santa Maria River basin, the objective of this study was to investigate whether the new lithologies described recently may be responsible for a greater var

2. Cordão Formation: loess deposits in the southern coastal plain of the state of Rio Grande do Sul, Brazil
ABSTRACT Loess consists of silt-dominated sediments that cover ~10% of the Earth's surface. In southern South America it occurs in Argentina, Bolivia, Paraguay and Uruguay, and its presence in southern Brazil was never studied in detail. Here is proposed a new lithostratigraphic unit, Cordão Formation, consisting of loess deposits in the southern Brazilian

3. Analise de facies e modelo paleodeposicional da plataforma siliciclastica ordoviciana da Pre-Cordilheira Argentina / Facies analisys and paleodepositional model of the ordovician siliciclastic shelf of the Argentine Precordillera
This work consists in the study of sedimentological and paleodepositional features of four Ordovician lithostratigraphic units of the Precordillera Argentina: Portezuelo del Tontal Formation (PTF), Sierra de La Invernada Formation (SIF), Gualcamayo Formation (GF) and Los Azules Formation (LAF). The PTF is represented by alternating fine- to very fine grained

4. Geologia dos grupos Araí e Serra da Mesa e seu embasamento no sul do Tocantins
Esta dissertação apresenta os dados de litoestatigrafia, geoquímica e geocronologia dos grupos Araí e Serra da Mesa e do embasamento comum a esses grupos obtidos no Sul do Tocantins. Pretende-se com esses dados avançar no conhecimento das relações deposicionais entre os dois grupos, constante objeto de controvérsia; assim como estudar o embasamento p

5. Avaliacao de dados aerogamaespectrometricos e de sua integracao com imagens digitais TM/Landsat 5, no mapeamento geologico na Serra dos Carajas (PA) / Evaluation of aerogammaspectrometric data and their integration with Landst-TM digital images for geological mapping in the Serra dos Carajas (PA)
Two test-sites, covering the Serra dos Carajás sheet (56,5 x 56,5 kin) and the Pojuca belt (15,4 x 15,4 kin) were selected for geological investigation. Gammaspectrometric airborne data (eU, eTh, Total Count and eU/eTh) were acquired over part of the Serra dos Carajfis Mineral Province (Brazilian Amazon Region) during the 1975 and 1976 (PGBC - Brazil-Canada

6. Correlacionamento litoestratigrafico espectral de pocos de perfuracao / Spectral lithostratigraphic correlation of boreholes
Estudou-se a utilização de medidas espectrorradiometricas (400 a 1000 nm) para o correlacionamento litoestratigrafico de poços de perfuração da Bacia do Parnaíba (PI-MA), através de uma abordagem quantitativa e qualitativa envolvendo a aplicação seqüencial das seguintes técnicas estatísticas: Analise de Agrupamentos, Analise Fatorial, Analise Dis

7. Early Pleistocene 40Ar/39Ar ages for Bapang Formation hominins, Central Jawa, Indonesia
The Sangiran dome is the primary stratigraphic window for the Plio-Pleistocene deposits of the Solo basin of Central Jawa. The dome has yielded nearly 80 Homo erectus fossils, around 50 of which have known findspots. With a hornblende 40Ar/39Ar plateau age of 1.66 ± 0.04 mega-annum (Ma) reportedly associated with two fossils [Swisher, C.C., III, Curti
