A review of published papers and results analysis new material have allowed improvements on the palynostratigraphy Permian strata Paraná Basin in Rio Grande do Sul State. Based first last occurrences certain species pollen taxa, two palynozones are formalized, these Vittatina costabilis Lueckisporites virkkiae Interval Zones, ascending order. The Zone is subdivided into units, order Protohaploxypinus goraiensis Hamiapollenites karrooensis Subzones, recognized from glacial (Itararé Group)...
Based on analysis of previous zonations and new studies, an overview the palynological succession Upper Paleozoic strata ParanáBasinis given, data are introduced. The Cannanoropollis korbaensis Zone is renamed Vittatina costabilis Zone, one its subzones ( Caheniasaccites ovatus ) regarded as belonging to Protohaploxypinus goraiensis Subzone. Four interval zones characterize this stratigraphic section; in ascending order, these Ahrensisporites cristatus , Crucisaccites monoletus...
Este artigo apresenta uma avaliação da qualidade química água do Rio das Contas nas margens urbanas de Aurelino Leal, Bahia, utilizando o teste "16 em 1" para análise preliminar parâmetros como pH, dureza, alcalinidade, presença metais pesados e compostos nitrogenados (nitrito nitrato). A ausência estações tratamento esgoto, associada ao despejo resíduos domésticos crescimento exacerbado plantas aquáticas (como a baronesa, Eichhornia crassipes), aponta um cenário eutrofização desequilíbrio...
Abstract In order to further our understanding regarding the petroleum potential of Maniamba Basin, Mozambique, organic rich sediments from four outcrops were investigated. Organic-rich shales, claystones, sandstones and siltstones sampled for geochemical analyses that included Total Organic Carbon (TOC), Rock Eval Pyrolysis. The pyrolysis analysis showed TOC ranges good excellent, thus indicating a hydrocarbon generation. Based on hydrogen index (HI) versus oxygen (OI) diagram, most samples...
The Pennsylvanian-Permian interval of the Paraná Basin is relatively well-known on its palynological content. However, little has been published from Permian Serra Alta, Teresina and lower Rio do Rasto formations (Passa Dois Group). A total thirty seven core samples were collected along a vertical range 600 meters these units in two boreholes Congonhinhas Municipality, northeastern State, South Brazil, but only Formation part Serrinha Member yielded identifiable palynomorphs. Of recorded...
This paper presents new data about Early Permian (Cisuralian) strata, palynostratigraphy and absolute dating from the Copacabana Formation in central Bolivia. Recent stratigraphic palynologic marine transitional rocks at Apillapampa refine age of Cisuralian palynomorphs South America. Twelve samples interbedded with five volcanic ashes (processed productive) yielded 94 palynomorph species arranged two informal palynoassemblages: lower assemblage Vittatina costabilis corresponds to one sample...
The sedimentary section at the Quitéria outcrop (Pantano Grande, central portion of Rio Grande do Sul State, Brazil) carries diverse and abundant fossil associations plants palynomorphs. This includes coal deposits Early Permian Bonito Formation in Paraná Basin. contribution presents a taxonomic re-evaluation on paleobotanical records based an in-depth revision available data as well direct analysis from materials deposited collections (published unpublished). A list is presented, anlysis...
