The Mirassol d'Oeste Formation (cap dolomites) and the base of Guia limestones) represent cap carbonates Neoproterozoic Araras Group, located along southern border Amazonian Craton, central Brazil. Petrographical microfacies descriptions together with geochemical mineralogical data top formations in Tangará da Serra area allowed us to identify main diagenetic features (neomorphism, chemical compaction, fractures) evaluate terrigenous contribution. Dolomitization has been documented a...
In order to reassess and amend previously published palynological data drawn from the Novo Remanso Formation, central Amazonia, we revisited organic-rich samples their work using systematic quantitative biostratigraphic analyses, with possible implications in biodiversity paleoecological studies of Late Neogene deposits Amazonia. study area, Formation is characterized by sandstones mudstones deposited a meandering river environment. The assemblage comprises 46 morphotypes, including 21...
Samples from outcrops of the Miocene Solimões and Barreiras formations central coastal Amazon regions Brazil were analyzed palynologically. Assemblages fossil fungi identified, are described herein, their relevance to paleoenvironmental paleoclimatic studies in tropical discussed. The fungal assemblage comprises four spore groups, 19 species belonging 12 genera. Additionally, two new proposed. samples Formation contain following taxa: Mediaverrunites elsikii , mulleri Monoporisporites sp.,...
Microbialites are the most abundant life evidence in Precambrian sedimentary rocks. They produced by microbial interaction activity and processes reflecting paleoenvironmental conditions. The Ediacaran-Cambrian carbonate siliciclastic successions Southern Amazon Craton Central Brazil, provide a key opportunity to understand how metazoan coexisted with communities. spatial temporal distribution of microbialites as well morphological changes have been assessed, reinterpreting previous works...

[Google Scholar] is recorded for first time in Oligocene-Miocene Pirabas Formation of Northern Brazil. In these carbonate deposits, sinuosus characterized by horizontal, highly regular sinusoidal burrow systems with T- and H-shaped branching points. The main difference between S. described herein other occurrences worldwide anomalous...
On the southern edge of Amazonian Craton, Mirassol d’Oeste and Guia formations constitute cap carbonate Araras Group. Petrography, X-ray diffraction, quantification terrigenous material allowed identification detrital grains (e.g., mica, quartz, feldspar) in different proportions diagenetic features. The sequential leaching carbonates along a section upper portion Formation yielded 87Sr/86Sr ratios increasing from 0.7070 to 0.7077, which is considered primary Sr isotopic signature seawater....
Cap carbonates are exceptional deposits related to the end of Neoproterozoic low-latitude glaciations. In Tangará da Serra region, south Amazon craton, was described a carbonatic succession with approximately 20 m thick that includes upper part Mirassol d'Oeste Formation and base Guia Formation, respectively dolomitic calcareous caps basal Araras Group. The cap dolomite is composed pinkish peloidal dolograinstones planar low angle truncated laminations interpreted as shallow moderately deep...
Rochas carbonáticas são amplamente registradas na região oeste e centro-oeste do Estado Pará, borda Sul da Bacia Amazonas, correspondentes ao período Neocarbonífero. Esses depósitos incluídos sequência pensilvaniana-permiana correspondente a uma super de segunda ordem representada pelo Grupo Tapajós. A Formação Itaituba corresponde à porção transgressiva que precedeu expressiva continentalização formação Pangeia. Essa unidade é constituída carbonatos fossilíferos, arenito com estratificação...
Resumo Capas carbonaticas se traduzem num dos mais importantes depositos relacionados ao final das glaciacoes globais neoproterozoicas. Na regiao de Tangara da Serra, margem sul do Craton Amazonico, foi descrita uma sucessao carbonatica neoproterozoica aproximadamente 20 m espessura que inclui o topo Formacao Mirassol d’Oeste e a base Guia, respectivamente as capas dolomitica calcaria Grupo Araras. A capa composta por dolograisntones peloidais rosados com laminacao plano paralela...
The Silurian-Devonian interval of the Amazonas Basin exhibits low trace fossils diversity.Transgressive post-glacial deposits (upper Silurian) in Tapajós River edge shows a assemblage composed by Arthrophycus, Beaconites, Bifungites, Diplichnites, Lockeia, Monocraterion, Planolites and Phycodes, also indeterminate tubes arthropod scratches.This illustrates Cruziana Ichnofacies preserved laminated siltstone, wavy bedding sandstone with tabular sigmoidal cross-stratification.The integration...
