1. Distribution of European and African species of genus Diaptomus (Copepoda: Calanoida: Diaptomidae): a track analysis

ABSTRACT The distributional patterns of 13 species of Diaptomus Westwood, 1836 were analyzed using the panbiogeographical method of track analysis. Locality records were compiled from the literature and mapped for the construction of individual tracks for each species. These tracks were superimposed to find the generalized tracks. Four generalized tracks wer

2. Tecttôniica póss--riifftte na Baciia Pottiiguar

Os estudos sobre as bacias sedimentares brasileiras se concentram em sua fase rifte, enquanto a fase pós-rifte tem sido considerada um período de pouca atividade. A sequência pós-rifte da Bacia Potiguar, no extremo nordeste brasileiro, já foi considerada pouco deformada, contudo, inúmeros trabalhos vêm demonstrando como ela é afetada por importantes

3. Gênese, distribuição e caracterização dos espongilitos do noroeste de Minas Gerais

This study relates to the spongillites deposits that occurs in shallow ponds on a karstic planation surface developed on rocks of the Neoproterozoic São Francisco Supergroup. Cenozoic siliciclastics sediments are related to this surface and Mesozoic Areado Group rocks occur adjacent to the deposits. Field studies associated with the analysis of multispectra

4. Processos metalogenéticos em ambientes de arco magmático tipo andino, caso de estudo: mineralizações da região dos Andes Patagônicos setentrionais do Chile / Metallogenic processes in andean volcanic arc setting, study case: mineralizations in the Chilean North-Patagonion Andes

In the Patagonian Andes region between 41 and 44° S extensive and continuous plutonic rocks of the North-Patagonian Batholith north segment are exposed. During their evolution most of the granitic rocks were emplaced in metamorphic rocks and other parts were emplaced in Late Jurassic-Berriasan volcanic rocks, Early Cretaceous sedimentary and volcanic rocks,

5. EVOLUÇÃO TECTONOSSEDIMENTAR DA BACIA DOS PARECIS AMAZÔNIA

The Parecis basin is located in central-western Brazil, on the southwestern part of the Amazon craton, between the Rondônia and Guaporé fold belts. From west to east, the Parecis basin can be divided into three tectono-sedimentary domains: a tectonic low to the west, a central compartment characterized by a negative gravimetric anomaly, and a interior sag

Mezosoic-Cenozoic brittle tectonics of the Serra dos Órgãos range in the Rio de Janeiro State, southeastern Brazil, was investigated using morphostructural analysis and field surveys. The study area is a sector of the Serra do Mar coastal range, with summits over 2.200 m a.s.l., and is included in the central segment of the Neoproterozoic-Cambrian Ribeira

7. A interação entre os eventos tectônicos e a evolução geomorfológica da Serra da Bocaina, Sudeste do Brasil / The interaction between tectonic events and the landscape evolution of Bocaina Ridge, Southeastern Brazil

The Bocaina Ridge landscape is strongly controlled by both ductile and brittle structures related to the Ribeira Belt (Brasiliano Orogeny ca. 790-480Ma) and also to the mesozoic-cenozoic reactivations. The rocks were subdivided in four tectonic terrains accreted in the brasiliano collisional stages. The most prominent structures related to these collisions a

This study developed in the central part of Cuba, attempted to evaluate a gamma radiation dose rate, exploring the airbome geophysical survey possibilities in order to obtain a radiogeochemical characterization and the geological - structural mapping of environment for an area of about 16.500 km2. Besides, to dispose through this research, of results that co

A morpho-structural analysis was performed in the uplifted siliciclastic deposits of the Serra do Martins Formation along the Portalegre, Martins and Santana plateaux, in the southeastern and central regions of Rio Grande do Norte State. Due to the lack of biostratigraphic records, this formation has a disputable age.The adopted approach was based on the ana

10. Oxygen and evolutionary patterns in the sea: Onshore/offshore trends and recent recruitment of deep-sea faunas

Over the last 15 years a striking pattern of diversification has been documented in the fossil record of benthic marine invertebrates. Higher taxa (orders) tend to originate onshore, diversify offshore, and retreat into deep-water environments. Previous studies attribute this macroevolutionary pattern to a variety of causes, foremost among them the role of n

11. Superfamily Gondwanatherioidea: a previously unrecognized radiation of multituberculate mammals in South America.

Multituberculates were the longest-lived order of the Class Mammalia and, during the Mesozoic and early Cenozoic, were among the most diverse and abundant representatives of the class. However, until the recent discovery of two Cretaceous teeth, one from South America and one from Africa, they were known only from northern continents. Additional material of
