1. Microbial filaments in stromatolites and laminites of Balbuena III Sequence (Maastrichtian/Danian) of Yacoraite Formation in Metán-Alemania Sub-basin, Salta region, Argentina, and its alaeoenvironmental significance
RESUMO A Bacia de Salta localiza-se no noroeste argentino e sua origem está relacionada a um rifte intracontinental, formado durante o Cretáceo e início do Paleógeno. Subdivide-se em quatro sub-bacias (Lomas de Olmedo a leste; Sey a oeste; Tres Cruces a norte; e Metán-Alemania a sul) que foram preenchidas por sedimentos dos Subgrupos Pirgua (fase sin-ri

2. Significado tectônico dos depósitos de leques aluviais da Formação Santa Bárbara (Eo-Paleozóico) na região de Caçapava do Sul (RS, Brasil)
The alluvial fan deposits of Early Paleozoic Santa Bárbara Formation, located in Sul-rio-grandense Shield area of southernmost Brazil, have been analyzed here in terms of facies associations and tectonic significance. The investigated unit comprises conglomerates, sandstones, and siltstones, deposited probably under continental semi-arid climate conditions,

3. Razões isotópicas 87Rb/86Sr, 87Sr/86Sr e 143Nd/144Nd como traçadores de proveniência de rochas sedimentares siliclásticas: exemplos no Grupo Camaquã(Paleozóico interior; RS, Brasil)
The Rb-Sr and Sm-Nd isotopic systems are ideal in constraining the provenance of fine-grained clastic rocks. This is particularly true for continental, fluvio-lacustrine, sedimentary units deposited under semi-arid climate conditions, where mechanical desintegration of source rocks dominates the weathering processes. Three sets of red-colored, continental si

4. 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

5. Evolução tectono-estratigráfica e paleoclimática da formação maricá (Escudo Sul-Rio-Grandense, Brasil) : um exercício de geologia histórica e análise integrada de uma bacia sedimentar neoproterozóica
Significant improvement in the knowledge concerning the Neoproterozoic Maricá Formation of the Sul-riograndense Shield, southern Brazil, was obtained in the latest years. This contribution synthesizes recent data obtained though an integrated analysis of the lowermost unit of the “Camaquã Basin”. Stratigraphic and paleocurrent analyses, petrography, Sr

6. SOLANACEAE A. JUSS. DA SERRA NEGRA, RIO PRETO, MINAS GERAIS: TRATAMENTO TAXONÔMICO E SIMILARIDADE FLORÍSTICA
Serra Negra is part of the Serra da Mantiqueira ridge, which is situated in the south of Zona da Mata region, Minas Gerais state, near the municipalities of Bom Jardim de Minas, Lima Duarte, Olaria, Rio Preto and Santa Bárbara do Monte Verde. Due to its importance for the biodiversity conservation in Mantiqueira Corridor, studies on the flora have been init

7. Feições de interação vulcano-sedimentares: seu uso como indicadores de contemporaneidade no magmatismo Rodeio Velho (meso-ordoviciano) e no vulcanismo Serra Geral (cretáceo inferior)
Volcanic-sedimentary interaction features were studied in association with two volcanic events: Rodeio Velho Magmatism (470 Ma), associated to Santa Bárbara and Guaritas allogroups (Camaquã Basin), at the localities of Arroio Carajá and Passo do Moinho; and Serra Geral Volcanism (average age of 130 Ma), associated to the Botucatu Formation (Paraná Basin)
