Stratigraphic correlation is about making connections. It is a set of scientific activities that seek to match rock patterns across distances. ... Because of the way evolution has influenced life on Earth, there is a distinct sequence of appearances of organisms through time. This sequence of life begins four billion years ago, with the ...

The original ideas of Sloss and of Vail (building on the early work of Blackwelder, Grabau, Ulrich, Levorsen and others) that the stratigraphic record could be subdivided into sequences, and that these sequences store essential …

The recurrence of the same types of sequence stratigraphic surface through geologic time defines cycles of change in accommodation or sediment supply, which correspond to sequences in the rock record.

A sequence stratigraphic surface is a type of stratigraphic contact that invariably serves, at least in part, as a systems tract boundary. As systems tract boundaries, sequence stratigraphic surfaces mark changes in stacking patterns between the strata below and above the contact. This defining attribute separates a sequence stratigraphic ...

The stratigraphic sequence comprises genetic units resulted from multifaceted exchanges of accommodation and sedimentation such as (highstand ordinary regressive, low standing, transgressive, and ...

Late Archaean Supracrustals of the Goa-Dharwar sector (GDS) are composed of a thick sequence of greywacke sequence with narrow intercalations of quartzite, BIF and carbonates.

In this study, we collected fresh samples of basalts from quarries in the Mahabaleshwar and Koyna sections and the Dharwar basement rocks from Goa area, in order to document the …

The existence of several competing approaches to the definition and classification of sequence stratigraphic units (Figures 1 and 2) has prevented the inclusion of sequence stratigraphy in international stratigraphic codes.The various approaches differ in terms of (1) the nomenclature of systems tracts and sequence stratigraphic surfaces, (2) the selection of surfaces that should …

The Dharwar greenschist supracrustals (Goa group) overlie a basement of trondhjemitic (peninsular) gneiss and the entire sequence is intruded by granites, dolerites and gabbros (Figures 1 and...

Sequence Boundary – often an unconformity formed by erosion that separates different depositional cycles; Unconformity – surface separating older from younger rocks and representing a gap in the geologic record; Figure 5.18 – Seismic patterns for a stratigraphic sequence. The lines are seismic reflections.

The younger sequence is dominated by clastics, and is assigned to a new stratigraphic group formally termed the Ponda Group which is equivalent to the Chitradurga …

classification of sequences based on these mechanisms is provided in Sect. 7.6. 5.2 Elements of the Model The practical application of sequence-stratigraphic methods to the mapping of a basin-fill succession, either in outcrop or in the subsurface, involves the following: † The documentation of a succession of sequences, tracing

Keywords: Relative sea-level, accommodation, sequence stratigraphic surfaces, systems tracts,stratal stacking patterns. Introduction The introduction of sequence stratigraphy is the most recent and significant revolution in the field of sedimentology and stratigraphy. Since its inception, it has gradually evolved into process-based working

The stratigraphic architecture and sedimentological makeup of deep-water systems is complex, due to the interplay of multiple allogenic and autogenic processes, and the co-existence of multiple sediment sources and modes of sediment transport (Fig. 1).Despite this variability, field criteria can still be defined to identify the elements of the deep-water sequence …

A genetic stratigraphic sequence is the sedimentary product of a depositional episode. The sequence incorporates and reconciles depositional systems, bedding geometries, and bounding surfaces within the framework of cycles of basin-margin offlap and flooding. Each sequence consists of the progradational, aggradational, and retrogradational or ...

Third-, fourth-, and fifth-order sea level cycles model sequence deposition for petroleum exploration. A third-order sequence is a composite of fourth- and fifth-order sequences. The table below shows sea level cycle frequencies, thickness ranges, and stratigraphic names for third-, fourth-, and fifth-order sequences.

4.1 Now think about the sequence of strata you would see in one big outcrop, or in a series of outcrops in a small area. This is called a local section. Even though the physical dimensions of the outcrop might be fairly "equidimensional", you are seeing …

The sequence stratigraphic terms are defined in the Table. There are some significant differences in the sequence stratigraphic models for clastics and carbonates (see Figs 1 and 2) in view of the different controls on sedimentation, notably the mostly in situ generation of carbonate sediments and the imported nature of clastic sediments.

The Precambrian rock succession in Goa, representing the NW extremity of the South Indian Precambrian Craton, includes: (1) a low grade supracrustal sequence known as the Goa Group; and (2 ...

A stratigraphic sequence is bounded at the base and at the top by the same type of sequence stratigraphic surface; e.g., from a maximum flooding surface to the next maximum flooding surface in the stratigraphic succession, on condition that the strata between the sequence boundaries belong to one cycle of change in accommodation or sediment ...

The supracrustals that constitute the Goa Group of Gokul et al. (1985) can be divided into two lithostratigraphic sequences namely the Barcem Group and the Ponda Group. The former comprises predominantly greenstones (metabasalts) and rests on a basement of the 3300–3400 Ma Anmode Ghat trodhjemite gneiss with a crudely developed quartz-pebble …

Previous sequence stratigraphic interpretations of Desmoinesian strata in eastern Kansas are rare. Walton (1996) was the first to apply sequence stratigraphic concepts to Cherokee Group strata, concluding that numerous sequences exist, occurring above paleosols and at basal contacts of incised channels. Lange (2003)

In peninsular India, the Gondwana sediments were mainly deposited in four intracratonic basins, i.e. Pranhita-Godavari (PG), Damodar, Satpura, and Son-Mahanadi with a distinct post-Carnian hiatus (except for the PG Basin) (Chakraborty et al. 2003).The analysis of the shape of the outcrop belt, characteristics of the basin-fill and the orientation of the …
