1. White sand vegetation in an Amazonian lowland under the perspective of a young geological history
Abstract: What controls the formation of patchy substrates of white sand vegetation in the Amazonian lowlands is still unclear. This research integrated the geological history and plant inventories of a white sand vegetation patch confined to one large fan-shaped sandy substrate of northern Amazonia, which is related to a megafan environment. We examined flo

2. Integrating geological and airborne geophysical data to review the cartography of Rio Itanguá Batholith, Araçuaí Orogen, Brazil
ABSTRACT Rio Itanguá Batholith (RIB) is a plutonic body located in the Northern border of Guanhães block, one of the various basement blocks reworked within the Araçuaí orogen, Eastern Brazil. Although its existence is known since the beginning of the 20th century, its tectonic history remains poorly understood. The RIB was mapped at 1:100,000 scale in t

3. Diversity and evolution of Amazonian birds: implications for conservation and biogeography
Abstract: Amazonia has been a focus of interest since the early days of biogeography as an intrinsically complex and extremely diverse region. This region comprises an intricate mosaic that includes diverse types of forest formations, flooded environments and open vegetation. Increased knowledge about the distribution of species in Amazonia has led to the re

4. Historical biogeography of fishes from coastal basins of Maranhão State, northeastern Brazil
RESUMO A ictiofauna da Amazônia é uma das mais diversificadas do mundo, mas os peixes das bacias costeiras adjacentes do estado do Maranhão, no Nordeste do Brasil, ainda são pouco conhecidos. Utilizamos métodos filogeográficos, filogenia de comunidade e de diversidade beta filogenética para estudar a história biogeográfica de peixes das bacias coste

5. Fishes of the Amazon: diversity and beyond
Abstract: The Amazon basin houses a particular group of freshwater organisms, whose study tells the geological history of the region, how biological diversity was shaped, how it is maintained, and what it hides. The fish of the Amazon is represented by more than 3,000 known species distributed from the basal groups up to the more specialized ones. This speci

6. Inventory and assessment of geosites to stimulate regional sustainable management: the northern coast of the state of São Paulo, Brazil
Abstract: The reviewed and integrated geoheritage inventory of the northern coast of the state of São Paulo, Brazil, resulted in 43 geosites distributed in eight geological frameworks. The selected geosites are representative of a geological history from the Neoproterozoic (Brasiliano-Pan African Cycle) to the recent, covering a minimum 700-Ma timespan. Con

7. Terrestrial impact structures as geoheritage: an assessment method of their scientific value and its application to Brazil
ABSTRACT Terrestrial impact structures are geological and geomorphological features with particular importance to understand the history and evolution of the planet. Impact structures are scattered around the world but in many countries these features are under threat, essentially due to anthropic factors. Impact structures with higher scientific value shoul

8. Pedodiagenetic Characterization of Cretaceous Paleosols in Southwest Minas Gerais, Brazil
ABSTRACT The influence of post-burial geological processes on preserving pedogenic properties has great importance in identifying ancient paleosols both in the field and in a laboratory. However there are not many publications that focus on characterizing paleosol diagenesis. As temperature and pressure progressively increase, evidence of pedogenesis is modi

9. GEODIVERSIDADE E LÓGICAS TERRITORIAIS NA CHAPADA DIAMANTINA - BAHIA. / GEODIVERSITY AND LOGIC IN TERRITORIAL CHAPADA DIAMANTINA - BAHIA.
The Chapada Diamantina, located in the central part of Bahia state, has a rich geodiversity which happens to be the set of a variety of earth materials, forms and processes that constitute and shape the Earth, with scientific, cultural, educational and/or recreational value. This set consists of geologic formations and structures, morphology, mineral deposit

11. Incorporação quantitativa de dados de sismica 4D no processo de ajuste de historico / Quantitative incorporation of seismic 4D in history matching process
Good decision making related to oilfield management depends on reliability of production forecast which demands calibrated reservoir simulation models. Due to the complexity of the production history matching process, there are many models with reasonable match but, many times, with different forecasts, mainly due to important heterogeneities that are not ob

12. Metodologia para ajuste de historico de produção em campos de petroleo utilizando dados de saturação de perfis / Methodology for production history matching of petroleum fields utilizing logging saturation data
In the production history matching process, the reservoir simulation model is modified in a way that it becomes consistent with production data, keeping the observed restrictions of the geological characterization phase. This technique is limited, mainly in mature fields, when the production history is not reliable, or in the beginning of production, when th
