New models for evolution of magma-poor rifted margins based on a review of data and concepts from West Iberia and the Alps
Direct observation and extensive sampling in ancient margins exposed in the Alps, combined with drillhole and geophysical data from the present-day Iberia margin, result in new concepts for the strain evolution and near-surface response to lithospheric rupturing at magmapoor rifted margins. This paper reviews data and tectonic concepts derived from these two margins and proposes that extension,...
متن کاملControl of rheological stratification on rifting geometry: a symmetric model resolving the upper plate paradox
Numerical experiments reproduce the fundamental architecture of magma-poor rifted margins such as the Iberian or Alpine margins if the lithosphere has a weak mid-crustal channel on top of strong lower crust and a horizontal thermal weakness in the rift center. During model extension, the upper crust undergoes distributed collapse into the rift center where the thermally weakened portion of the ...
متن کاملSilicic volcanism: An undervalued component of large igneous provinces and volcanic rifted margins
Silicic volcanic rocks are associated with most, if not all, continental ×ood basalt provinces and volcanic rifted margins, where they can form substantial parts of the eruptive stratigraphy and have eruptive volumes >104 km3. Poor preservation of silicic volcanic rocks following kilometer-scale uplift and denudation of the volcanic rifted margins, however, can result in only deeper level struc...
متن کاملVolcanic passive margins: another way to break up continents
Two major types of passive margins are recognized, i.e. volcanic and non-volcanic, without proposing distinctive mechanisms for their formation. Volcanic passive margins are associated with the extrusion and intrusion of large volumes of magma, predominantly mafic, and represent distinctive features of Larges Igneous Provinces, in which regional fissural volcanism predates localized syn-magmati...
متن کاملStress Controls of Monogenetic Volcanism: A Review
The factors controlling the preparation of volcanic eruptions in monogenetic fields are still poorly understood. The fact that in monogenetic volcanism each eruption has a different vent suggests that volcanic susceptibility has a high degree of randomness, so that accurate forecasting is subjected to a very high uncertainty. Recent studies on monogenetic volcanism reveal how sensitive magma mi...
