A seismic sequence is defined as the stratigraphic interval between two consecutive sequence boundaries, representing two marine regression events with a marine transgression event at the middle. Thus a seismic sequence is further subdivided with a basal unit of regressive systems tract, a transgressive systems tract at the middle, and a ...
[9] [10] The advent of seismic stratigraphy made it possible to identify sequences representing shorter period of time ranging in duration from tens of thousands to a few million years; and to compare the sequence stratigraphic history around the globe. This in turn led to sequence stratigraphy becoming systematized and understood to have ...
Henry Posamentier. Henry William Posamentier (born December 4, 1948) is an American geologist.He helped pioneer and develop the modern approach to sequence stratigraphy, [1] blending the disciplines of sedimentology, stratigraphy, and depositional systems analysis, largely within the context of oil and gas exploration.
Vail was well known for being the first to realize that seismic reflections do not follow lithofacies boundaries but instead follow geologic time lines. This concept gave rise to the field of seismic stratigraphy. [3] In 2005 he earned the Benjamin Franklin Medal for his pioneering works in sequence stratigraphy.
Wheeler's work in the 1950 and 1960s was pivotal in the later development of sequence stratigraphy, which is still used today, for example by petroleum industry geologists. [3] His 1964 paper, Baselevel, Lithosphere Surface, and Time-Stratigraphy [ 4 ] evolved the concept of base level to emphasize the continuous spatial and temporal nature of ...
Ancient channelized features in outcrops have long been reported in literature, but their significances in eustatic sea-level variation and chronostratigraphy have not been recognized until Vail et al (1977) put them in the context of sequence stratigraphy through seismic stratigraphy.
Lee Lawyer said in Sheriff’s citation for the Maurice Ewing Medal that Sheriff was in the forefront of such major trends in geophysical theory as hydrocarbon indicators, sequence stratigraphy, and reservoir geophysics. In addition, he was responsible for the first poster session at an SEG Annual Meeting, arranged the SEG technical ...
Construction of a seismic sequence stratigraphy allows the examination of the interaction of tectonics and sedimentation. On this basis the Cheshire Basin can be divided roughly into two areas: a westerly area close to the western basin margin and an easterly area nearer to the Carboniferous Wem/Red Rock Fault.
