“…Segundo a carta estratigráfica da Bacia do Paraná (Milani et al, 2007;Holz et al, 2010), a Formação Rio do Rasto pertence ao Grupo Passa Dois e está incluída na sequên-cia deposicional Meso/Neopermiana da Bacia do Paraná (Figura 2). A formação foi dividida por Gordon Jr. (1947) nos membros Serrinha (inferior) e Morro Pelado (superior).…”

Disponível on-line no endereço www.igc.usp.br/geologiausp -29 -Resumo O topo da Formação Rio do Rasto, Bacia do Paraná, corresponde ao Membro Morro Pelado, unidade composta pela associação de depósitos fluviais, eólicos e lacustres. A fim de retratar os elementos deposicionais presentes e caracterizar o estilo de sedimentação fluvial, uma análise faciológica foi realizada na faixa de afloramentos do leste dos estados de Santa Catarina e do Paraná. O Membro Morro Pelado é formado por quatro associações litofaciológicas: A, B, C e D. A associação litofaciológica A corresponde aos depósitos de canais meandrantes, presente na zona intermediária de um sistema fluvial distributário. A associação litofaciológica B pertence à zona distal do sistema fluvial, onde predominam depósitos de fluxos em lençol e canais retilíneos rasos (espraiamentos terminais fluviais). A associação litofaciológica C é definida como um sistema deltaico dominado por rios desenvolvido em momentos de subida do nível de base e formação de lagos. Por fim, a associação litofaciológica D caracteriza-se por depósitos de dunas (DU) e interdunas (IDU) recorrentes adjacentes a todas as porções do sistema fluvial distributário. O empilhamento estratigráfico revela aumento da quantidade e espessura dos depósitos eólicos em direção ao topo, indicando incremento da aridez no ambiente deposicional e expansão dos campos de dunas em direção às margens da bacia.Palavras-chave: Sistema fluvial; Clima semiárido; Interação fluvial-eólico; Elemento arquitetônico. AbstractThe Late Permian Morro Pelado Member is the upper part of the Rio do Rasto Formation of Paraná Basin and is composed of an association of fluvial, eolian and lacustrine deposits. In order to depict its facies associations and depositional elements as well as to characterize the fluvial style, a facies and architectural element analysis was carried out in the eastern outcrop belt in Santa Catarina and Paraná States, southern Brazil. Four facies associations (FA) were recognized: FA-A is interpreted as mixed-load meandering fluvial systems, with conspicuous laterally accreted macroforms, levees and floodplain fines; FA-B was deposited as terminal splays in the distal parts of the fluvial system, where sheet floods prevailed; FA-C defines a fluvial-dominated lacustrine delta formed in response to episodes of extreme flooding and rising water table in the terminal splay zone; FA-D comprises eolian dunes, wet and damp interdunes and eolian sand sheets that occur interbedded with the fluvial and lacustrine deposits marking periods of aridization in the alluvial plain. The vertical stacking pattern shows an upward increase in frequency and thickness of eolian deposits recording progressive expansion of the erg systems towards basin margins in response to progressive drying combined with high rates of accommodation and sediment supply.

“…The lower Taquaral Member of the Irati Formation comprises siltstones and gray to black mudstones, and the upper Assistência Member has organic-rich mudstones and shales interbedded with limestones (Holz et al 2010). The upper Assistência Member is rich in total organic carbon (TOC = 10-25 %; e.g., high in the Lauro Müller region, TOC = 20%).…”

The occurrences of glassy rocks containing long and curved phenocrysts in the Paraná volcanic province, South America, are here interpreted as paralavas. The large number of thin (0.1-0.5 m) dikes and sills of glassy volcanic rocks with hopper, hollow or curved, large crystals of clinopyroxene (up to 10 cm), plagioclase (up to 1 cm), magnetite and apatite are contained in the core of thick (>70 m) pahoehoe flows. They are strongly concentrated in the state of Paraná, coincident with the presence of the large number of dikes in the Ponta Grossa arch. These rocks were previously defined as pegmatites, although other names have also been used. A paralava is here interpreted as the product of melting of basaltic rocks following varied, successive processes of sill emplacement in high-kerogen bituminous shale and ascent of the resultant methane. As the gas reached the lower portion of the most recent lava flow of the volcanic pile, the methane reacted with the silicate and oxide minerals of the host volcanic rock (1,000 ºC) and thus elevated the local temperature to 1,600 ºC. The affected area of host rock remelted (possibly 75 wt.%) and injected buoyantly the central and upper portion of the core. This methane-related mechanism explains the evidence found in the paralavas from this volcanic province, one of the largest in the continents.
