Continental margins have been the focus of recent hydrocarbon exploration, comprising relatively untapped reserves of oil and gas. They are also key to the future energy paradigm - they contain vast accumulations of natural gas and demonstrate, at the same time, a vast potential as CO2sinks. Giant oil and gas fields are now produced in offshore areas of Brazil, North America, Africa and Middle East, using advanced production techniques that include carbon capture and storage. To better understand how continental margins evolved into hydrocarbon prolific regions, it is necessary to integrate vast data such as: a) seismic reflection surveys of high quality and depth of penetration, b) information on magmatic sources and their relative timings, d) mathematical and physical models representing the margins’ thermal and structural evolutions, e) natural and induced seismological data sampling the deep crust and upper mantle, f) field analogues reflecting the sedimentary and tectonic processes that led to their formation.
The Journal of Marine and Petroleum Geology thus announces a special issue entitled ‘Continental margins unleashed: From early inception to continental breakup’ to reflect recent advances on our understanding of continental margins.
This Special Issue will focus on the key underlying scientific issues associated with favourable and less-favourable settings for hydrocarbon exploration on continental margins. Authors should submit novel analysis and state-of-the-art data sets from continental margins. Manuscripts are expected to go beyond local case study analyses and data collection only.
The Special Issue will be organised in the following sections:
·Rift inheritance and geometry of continental margins- A section devoted to those seismic-stratigraphic proxies that corroborate (or not) the mathematical models developed in many other places. Of importance are also the impact of distinct rift-margin geometries on the overlying stratigraphic architectures, and the parameters controlling this variability (e.g. inheritance, fault growth models).
·Breakup processes, depositional facies and associated magmatism- A section devoted to understanding the volumes of magmatism that are 'typical' of fully rifted margins. Depositional and mathematical models explaining continental breakup in magma-rich vs. magma-poor margins will also fit in this section.
·Salt (giants) and gravitational tectonics in syn-rift and early post-rift settings- This section will tackle the importance of salt in the early (and late) structural evolution of continental margins. We welcome contributions from Salt Giants such as the GoM, South Atlantic and Mediterranean Sea, and other hydrocarbon-rich salt basins.
