“…This notion also fits with the biological underpinning of the morphology as proposed by Blakeway and Hamblin (2014) and Schlager and Purkis (2014), and is also in accordance with the observations made by Colpaert et al (2011) in the Barents Sea subsurface. While unconstrained by water depth, platform-interior reefs grow as circular patch reefs.…”

“…Further, it is clear that the best seismic expression of the low-relief Palaeoaplysina and high-relief bryozoan buildup complexes is obtained when they are imaged with RGB-blended colour schemes in spectral decomposition volumes (e.g. Colpaert et al, 2007Colpaert et al, , 2011. Similar, elongated-to-polygonal, features were distinguished in all three of the considered seismic slices, despite the fact that they encompass buildups constructed by both photozoan and heterozoan communities.…”

“…Although very different biota are identified, recticular patterns were revealed for both photozoan carbonate growth of Bashkirian to Sakmarian age and heterozoan buildup growth during Artinskian age.The morphometric analysis conducted byColpaert et al (2011) revealed subtle variations in the geomorphic growth of buildups dependent on palaeoenvironment which could be broadly related to the availability of accommodation. For instance, the authors report the form of the polygonal patterning to vary dependent on position on the platform-top, slope, or proximity to active fault blocks (faulting seems to have exerted principal control on the palaeo-relief of the platform-top).…”

Upper Carboniferous–Lower Permian Palaeoaplysina build-ups on Svalbard: the influence of climate, salinity and sea-level

Upper Carboniferous–Lower Permian Palaeoaplysina build-ups on Svalbard developed on a partly restricted marine warm-water carbonate platform at low palaeo-latitudes. The Palaeoaplysina build-ups mostly have a flat-topped tabular geometry, representing the mature stage of build-up growth. With decreasing accommodation space, continued vertical growth was hampered and lateral growth became dominant. The tabular growth form of the build-ups is probably a result of lateral amalgamation of several minor mounds. In central Spitsbergen many of the tabular build-ups form parts of continuous ridges or ring-shaped to polygonal build-up complexes encircling a lagoon. Lateral interfingering between bedded fusulinid dolostones along the build-up margins and barren dolostones further out in the lagoon may indicate increasing salinity from the lagoon margin to the central part. These lateral facies changes are often associated with evaporites (gypsum) and low biodiversity, especially abundant euryhaline fusulinids or even barren beds. On the sea side of the Palaeoaplysina build-ups, the frequent renewal of normal saline seawater allowed the highest biodiversity (e.g. stenohaline crinoids). The uppermost part of some build-ups contain Microcodium, indicating intermittent subaerial exposure and vegetation cover during lowstand, probably caused by eustatic sea-level changes and/or local tectonics. The biota of the build-ups and their lateral sediments is typical for a shallow marine chloroforam association, indicating a tropical climate during deposition.

Improved seismic data quality in the last 10–15 years, innovative use of seismic attribute combinations, extraction of geomorphological data, and new quantitative techniques, have significantly enhanced understanding of ancient carbonate platforms and processes. 3D data have become a fundamental toolkit for mapping carbonate depositional and diagenetic facies and associated flow units and barriers, giving a unique perspective how their relationships changed through time in response to tectonic, oceanographic and climatic forcing. Sophisticated predictions of lithology and porosity are being made from seismic data in reservoirs with good borehole log and core calibration for detailed integration with structural, paleoenvironmental and sequence stratigraphic interpretations. Geologists can now characterise entire carbonate platform systems and their large-scale evolution in time and space, including systems with few outcrop analogues such as the Lower Cretaceous Central Atlantic “Pre-Salt” carbonates. The papers introduced in this review illustrate opportunities, workflows, and potential pitfalls of modern carbonate seismic interpretation. They demonstrate advances in knowledge of carbonate systems achieved when geologists and geophysicists collaborate and innovate to maximise the value of seismic data from acquisition, through processing to interpretation. Future trends and developments, including machine learning and the significance of the energy transition, are briefly discussed.
