“…Subsequent reiteration of the T-R sequence model has combined the marine sequence boundary of Johnson and Murphy (1984) with the fluvial sequence boundary of the depositional sequence model. In this revised definition, the T-R sequence model uses a composite sequence boundary which includes the subaerial unconformity and the marine portion of the maximum regressive surface (Embry and Johannessen, 1992;Figures 4, 23, & 24). This model emphasizes the importance of subaerial unconformities, as originally outlined by the depositional sequence school (e.g., Haq et al, 1987;Van Wagoner et al, 1988, 1990Christie-Blick, 1991), and the ease of recognition of maximum regressive surfaces in shallow-water systems.…”

It has been accepted for inclusion in Papers in the Earth and Atmospheric Sciences by an authorized administrator of DigitalCommons@University of Nebraska -Lincoln. AbstractSequence stratigraphy emphasizes facies relationships and stratal architecture within a chronological framework. Despite its wide use, sequence stratigraphy has yet to be included in any stratigraphic code or guide. This lack of standardization reflects the existence of competing approaches (or models) and confusing or even conflicting terminology. Standardization of sequence stratigraphy requires the definition of the fundamental model-independent concepts, units, bounding surfaces and workflow that outline the foundation of the method. A standardized scheme needs to be sufficiently broad to encompass all possible choices of approach, rather than being limited to a single approach or model.A sequence stratigraphic framework includes genetic units that result from the interplay of accommodation and sedimentation (i.e., forced regressive, lowstand and highstand normal regressive, and transgressive), which are bounded by "sequence stratigraphic" surfaces. Each genetic unit is defined by specific stratal stacking patterns and bounding surfaces, and consists of a tract of correlatable depositional systems (i.e., a "systems tract"). The mappability of systems tracts and sequence stratigraphic surfaces depends on depositional setting and the types of data available for analysis. It is this high degree of variability in the precise expression of sequence stratigraphic units and bounding surfaces that requires the adoption of a methodology that is sufficiently flexible that it can accommodate the range of likely expressions. The integration of outcrop, core, well-log and seismic data affords the optimal approach to the application of sequence stratigraphy. Missing insights from one set of data or another may limit the "resolution" of the sequence stratigraphic interpretation. 1 2 c a t u n e a n u e t a l . i n e a r t h -science r e v i e w s 92 (2009)

Evolução estratigráfica da Sequência Neocarbonífera-Eotriássica da Bacia do Parnaíba, Brasil

RESUMO:A Sequência Neocarbonífera-Eotriássica corresponde ao terceiro grande ciclo sedimentar da Bacia do Parnaíba e concerne litoestratigraficamente ao Grupo Balsas. Essa sequência é descrita como um conjunto de rochas cujos sedimentos foram depositados em um ambiente complexo, clástico/evaporítico de mar raso, gradando para um ambiente lacustre/ desértico. O principal objetivo deste trabalho foi realizar uma análise estratigráfica da Sequência Neocarbonífera-Eotriássica, visando uma melhor compreensão da sua evolução. Tal análise teve por base dados de poços e algumas seções sísmicas. Para o intervalo estratigráfico em questão foram identificadas três sequências deposicionais. A Sequência 1 corresponde a rochas que foram depositadas inicialmente a partir de um sistema fluvial, que passa para um sistema marinho raso implantado durante uma fase transgressiva e, posteriormente, evolui para um sistema deltaico. A Sequência 2 corresponde a rochas que foram depositadas a partir de um sistema deposicional lacustre/desértico, representando uma fase regressiva importante que culmina com a implantação de um sistema desértico, o qual corresponde à Sequência 3. Na análise sismoestratigráfica foi possível reconhecer as superfí-cies cronoestratigráficas e os tratos de sistemas identificadas em poços e analisar a sua expressão lateral. De modo geral, as sismofácies reconhecidas nas seções sísmicas apresentam-se com configurações paralelas a subparalelas, com grande continuidade lateral, sugerindo uma homogeneidade nas taxas de sedimentação durante a deposição dessas sequências, nesse setor da bacia.
