Both magmatic and tectonic processes contribute to the formation of volcanic continental margins. Such margins are thought to undergo extension across a narrow zone of lithospheric thinning (~100 km). New observations based on existing and reprocessed data from the Eastern North American Margin contradict this hypothesis. With~64,000 km of 2-D seismic data tied to 40 wells combined with published refraction, deep reflection, receiver function, and onshore drilling efforts, we quantified along-strike variations in the distribution of rift structures, magmatism, crustal thickness, and early post-rift sedimentation under the shelf of Baltimore Canyon Trough (BCT), Long Island Platform, and Georges Bank Basin (GBB). Results indicate that BCT is narrow (80-120 km) with a sharp basement hinge and few rift basins. The seaward dipping reflectors (SDR) there extend~50 km seaward of the hinge line. In contrast, the GBB is wide (~200 km), has many syn-rift structures, and the SDR there extend~200 km seaward of the hinge line. Early post-rift depocenters at the GBB coincide with thinner crust suggesting "uniform" thinning of the entire lithosphere. Models for the formation of volcanic margins do not explain the wide structure of the GBB. We argue that crustal thinning of the BCT was closely associated with late syn-rift magmatism, whereas the broad thinning of the GBB segment predated magmatism. Correlation of these variations to crustal terranes of different compositions suggests that the inherited rheology determined the premagmatic response of the lithosphere to extension.

“…Another attempt to decarbonize gas is the steam reformation with fossil fuels: For this, fossil natural gas is reformed (or thermal cracked in the future 21 ) and the resulting CO2 is (not completely) captured and injected into old offshore gas fields. This process is also known as CCOS (Carbon Capture and Offshore Storage) (Kim et al 2016;Cumming et al 2017).…”

This paper discusses the potential role of fossil natural gas (and other gases) in the process of the energy transformation in Europe on its way to complete decarbonization. Mainstream conventional wisdom has it that natural gas, perhaps in combination with other gases, should maintain an important role in the energy mix, fir st, as a "bridge fuel", and then through a gradual transition towards decarbonized gases. This is most comprehensively rolled out in three consecutive discussion papers by Jonathan Stern from the Oxford Institute for Energy Studies (2017bStudies ( , 2017aStudies ( , 2019. Based on an in-depth assessment of the ambitious climate targets of the EU and the subsequent need for far-reaching decarbonization, as well as on results from energy system modeling, a contrasting result emerges, where the disappearance of fossil natural gas and its corresponding infrastructure is the next logical step of the transformation process in Europe. The lack of an economic perspective for nuclear power and the absence of a plausible deployment of large-scale carbon-dioxide removal technologies (CDR) imply that natural gas has no "sweet spot" any longer in the decarbonization process. In other words: Fossil natural gas is no longer part of the solution to the challenge of climate change, but has become part of the problem. Over the last years, the phasing out of natural gas in Europe has already started, and will continue until its complete phase-out, most likely in the 2040s, i.e. only two decades from now. The decline of natural gas in Europe has implications for the short-and longer-term aggregate and sectoral energy mix, but also for the future of the lumpy infrastructure, that has been developed over the last decades for a growing market.Today, investments into natural gas infrastructure are likely to produce stranded assets, as we show in three concrete cases: The € 10 bn. investment into the North Stream 2 pipeline are not necessary to assure European supply security, nor to make a return on investment; projects of new LNG terminals on the shore of the German North Sea (Brunsbuettel, Stade, Wilhelmshaven) lack a business case; and new natural gas power plants are likely to be unprofitable. The paper proposes to replace the dominant narrative ("natural gas in decarbonizing European energy markets") with what we consider a more coherent narrative in the context of decarbonization: Fossil natural gas exit.
