Trevor Elliott; C atuneanuO. Based on the results from this study, three 3rd order sequences have been identified.
However in shallower settings the transgression that accompanies a base level rise may erode the upper surface of the underlying regressive sequence Loutit et al. This chapter presents a brief account of the main methods that need to be integrated into a comprehen- sive sequence stratigraphic ccatuneanu, including facies analysis of ancient deposits outcrops, core and modern environments; analysis of well-log signatures; analysis of seismic data; and the achievement of time control via relative and absolute age determinations.
The third FA consists of limestones of chemical and biochemical cauneanu and is related to a marine condition.

Principles of flow and sediment motion Principles of sedimentation All natural systems tend toward a state of equilibrium that reflects an optimum use of energy. Sequences 1 and 3 are partial but the sequence 2 is the main and most complete one of the formation in the studied area. This surface lies over the youngest clinoform paleoseafloor of regression and is onlap ped by transgressive strata Catuneanu, Based on the petrographic results and log data, 7 facies are determined in the formation, which are mainly composed of sandstone and shale.
Along such profiles, there is a perfect balance between sediment removal and accumulation. Within the nonmarine portion of the basin, a distinction can be made between the steeper-gradient alluvial plain, which captures the upstream reaches of fluvial systems, and the gently sloping coastal plain that may develop within the downstream reaches of the fluvial environment Fig.
According to their reservoir quality, these facies associations show a decreasing trend in porosity and permeability values from FA1 to FA3. The study of depositional systems is intimately related to the concepts of facies, facies associations, and facies models, which are defined in Fig.
VolumeNumber 6. This state of equilibrium is expressed as a graded profile in fluvial systems, or as a base level in coastal to marine systems. As such, facies analysis is an integral part of both sedimentology and sequence stratig- raphy, which explains the partial overlap between these disciplines Fig. Citing articles via Google Scholar.
ISBN 0 Elements of what we now understand as sequence stratigraphy had been rumbling along in the background for some time before the explosion that started to appear in the scientific literature in the late s. Cxtuneanu was for this reason that Posamentier and Vail, thought this surface should be named the transgressive surface.

After a contentious and often turbulent start, sequence stratigraphy is now widely accepted as an additional tool in the kit of sedimentary geologists striving to interpret the record of sediments and sedimentary rocks. It is easy, with the benefit of hindsight, 206 find key elements of the concepts in papers published during the catuneaun and s but we had to wait until the s for these Facies analysis is of paramount importance for any sequence stratigraphic study, as it provides critical clues for paleogeographic and paleoenvironmental reconstructions, as well as for the definition of sequence stratigraphic surfaces.
Facies analysis is therefore a prerequisite for any sequence stratigraphic studies. The coastal prism is wedge shaped, and expands landward from the coastal environment by onlapping the cahuneanu topography in an upstream direction.

The second FA consists of fluvial sandstones and sandwich by marine shales and is related to fluvial-dominated shallow marine setting estuary to delta. Coastal environments are critical for sequence stratigraphy, as they record the history of shoreline shifts and are most sensitive in providing the clues for 1.

Flow velocity is directly proportional to slope magnitude. Marine environments – regressive river mouths: You do not currently have access to this article. As environmental energy decreases, coarser-grained sediments are deposited first. These facies are classified into three facies associations FA based on their sedimentological properties and environmental conditions.
