1. Stratigraphy and tectonic setting of the Barriga Negra Formation in Uruguay: an update
Abstract The aim of this work is to propose a new stratigraphic scheme of the Barriga Negra Formation, in order to solve the controversies in one of the most discussed units of Uruguay. Here, we introduce a new map (unmodified since 1984) and amend the stratigraphic profile for the Barriga Negra Formation, establishing the correct sequence, order and thickne

2. 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

3. Paleoenvironmental Evolution of Continental Carbonates in West-Central Brazil
ABSTRACT This paper presents a sedimentological and stratigraphical study of Quaternary (Middle to Late Pleistocene/Holocene) continental carbonates outcrops inside Pantanal Basin and its surroundings, especially in Serra da Bodoquena, Pantanal do Miranda and Corumbá/Ladário plateau, in the state of Mato Grosso do Sul, as well as in Serra das Araras, in th

4. Geoquímica e geocronologia sedimentarno estudo das sequências paleozoica e pré-rifte de bacias do nordeste brasileiro
Integrated application of geochemical and sedimentary geochronology in pelitic rock samples from the basal section of the northeastern Brazilian continental margin, especially those of the Paleozoic and pre-rift sequences is the main goal of this thesis. The results are presented and discussed in three technical articles. Two of these articles present the Rb

5. Tectonic control on the stratigraphic framework of Late Pleistocene and Holocene deposits in Marajó Island, State of Pará, eastern Amazonia
A visão tradicional de que a Amazônia brasileira localiza-se em ma área tectonicamente estável desde o Cretáceo está mudando perante a crescente documentação de reativações de falha, até mesmo durante o Holoceno. Como o registro sedimentar respondeu a esses eventos é um tema que permanece por ser abordado com base em dados de campo. Este trabalho

6. Arquitetura estratigráfica e arcabouço estrutural dos depósitos fluviais albianos da base da Formação São Mateus no Norte da Bacia do Espírito Santo
The main aim of this dissertation is make at the high-resolution stratigraphic subdivision of the basal section from the São Mateus Formation, Albian the Espírito Santo Basin. The interval studied is consists predominantly of alluvial deposits. Against the difficulties presented for the stratigraphic correlation of these deposits, as discussed by Wright &M

7. Micropaleontolgy applied to the stratigraphic and paleoclimatic interpretation of the transition between the Paranoá Group and São Francisco Supergroup (Neoproterozoic, Cabeceiras, Goiás) / Micropaleontologia aplicada na interpretação estratigráfica e paleoclimática da transição entre o Grupo Paranoá e o Supergrupo São Francisco (Neoproterozóico, Cabeceiras, GO)
The Proterozoic record of the Fazenda Funil, near Cabeceiras, GO, includes three sedimentary units: carbonate at the top of Paranoá Group, diamictite of the Jequitaí Formation, and a succession of shale, marl-shale rhythmites, and carbonate of the Sete Lagoas Formation. Microfossiliferous chert occurs in these three units in the form of lenses in the Paran

8. Tectônica e sedimentação na Bacia do Camaquã Central (RS): exemplos do Grupo Guaritas e do Grupo Santa Bárbara / Tectonics and sedimentation in Central Camaquã Basin: the Guaritas Group and the Santa Bárbara Group
The relationship between tectonics and sedimentation plays a primordial role in the understanding of sedimentary successions. On the other hand, the study of pre-Silurian fluvial deposits represents a challenge due to the lack of interaction between land plants and river systems which characterizes post-Silurian environments. The Camaquã Basin (Ediacaran to

9. Análise tectono-estratigráfica da Faixa de dobramento Paraguai meridional na Serra da Bodoquena e depressão do Rio Miranda, MS / Tectonostratigraphic analysis of the southern Paraguay fold belt in Serra da Bodoquena and Rio Miranda depression, MS
This work aims to characterize the geological and structural context of the Southern Paraguay Folded Belt, and to understand the stratigraphic relationships between the Puga Formation, Corumbá and Cuiabá groups. Regional geological reconnaissance work and detailed geological-structural field sections were carried out, with petrographic and structural analy

10. Caracterização tectono-estratigráfica da sequência transicional na sub-bacia de Sergipe
This thesis deals with the tectonic-stratigraphic evolution of the Transitional Sequence in the Sergipe Sub-basin (the southern segment of the Sergipe-Alagoas Basin, Northeast Brazil), deposited in the time interval of the upper Alagoas/Aptian stage. Sequence boundaries and higher order internal sequences were identified, as well as the structures that affec

11. A história do intemperismo na Província Borborema Oriental, Nordeste do Brasil: implicações paleoclimáticas e tectônicas
Until some years ago, weathering geochronology was primarily based on the K-Ar and 40Ar/39Ar dating of supergene minerals. Recent advances in the analysis of supergene goethite by the (U-Th)/He method expanded the number of suitable minerals for such purpose, as well as the time of application for weathering geochronology. This study represents the first sys

12. High resolution stratigraphy framework for carbonatic deposits of terciary of the Basin Campos / Geração de um arcabouço estratigráfico de alta resolução para depósitos carbonáticos terciários da Bacia de Campos
The Siri Member is of great importance due to the heavy oil content that is present on the carbonate platform developed during the Tertiary. Considering this importance, we conducted a study with the objective of generating a high resolution stratigraphic framework, on 3rd order sequences, using the interpretation of two seismic sections and the analysis of
