The processes related to hyperextension, exhumed mantle domains, lithospheric breakup, and formation of first unequivocal oceanic crust at magma-poor rifted margins are yet poorly understood. In this paper, we try bring new constraints ideas about these latest deformation stages by studying the most distal Australian-Antarctic margins. We propose a interpretation, linking sedimentary architectures nature type basement units, including hyperextended crust, mantle, embryonic, steady state...
Abstract Rifted margins are commonly defined as magma-poor or magma-rich archetypes based on their morphology. We re-examine the prevailing model inferred from this classification that have excess decompression melting at lithospheric breakup compared with steady-state seafloor spreading, while inhibited melting. investigate magmatic budget related to along two high-resolution long-offset deep reflection seismic profiles across SE Indian (magma-poor) and Uruguayan (magma-rich) rifted...
Continental rifts and passive continental margins show fundamental along‐axis segmentation patterns that have been attributed to one or a number of different processes: extensional fault geometry, variable stretching along strike, preexisting lithospheric compositional structural heterogeneities, oblique rifting, the presence absence eruptive volcanic centers. The length width scales rift stage fault‐bounded basin systems change during late evolution new plate boundary, role magmatism may...
Rifting between Arabia and Somalia started around 35 Ma followed by spreading at 17.6 in the eastern part of Gulf Aden. The first-order segment Alula-Fartak Socotra-Hadbeen fracture zones is divided into three second-order segments with different structure morphology. Seismic reflection data were collected during Encens Cruise 2006 on northeastern margin. In this study, we present results Pre-Stack Depth Migration multichannel seismic from western segment, which allows us to propose a...
[1] New lithospheric analog models of oblique rifting presented here capture the main characteristics natural rifts and provide insights into fault evolution, basin segmentation, mantle exhumation occurring during rift localization. We present two models: one with a preexisting weakness (model B) another no zone A). Both have an obliquity about 40°. The results are as follows. (1) populations, especially early stages deformation, composed faults that in strike largely intermediate between...
The rifting between Arabia and Somalia, which started around 35 Ma, was followed by oceanic accretion from at least 17.6 Ma leading to the formation of present-day Gulf Aden. Bathymetric, gravity magnetic data Encens-Sheba cruise are used constrain structure segmentation basin separating conjugate continental margins in eastern part Aden 51°E 55.5°E. Data analysis reveals that domain along this ridge section is divided into two distinct areas. Eastern area characterized a shorter wavelength...
Abstract Asymmetry or symmetry of magma‐poor rifted margins refers commonly to the crustal architecture and occurrence absence large‐scale extensional detachment faults. While distal parts are often considered be asymmetric, observation downlapping sedimentary sequences over exhumed mantle domains at conjugate suggests a symmetric evolution during exhumation. On basis seismic observations along Iberia–Newfoundland Australia–Antarctica margins, we propose that their most show evidence for...
Abstract The source of massive magma production at volcanic rifted margins remains strongly disputed since the first observations thick lava piles in 1980s. However, volumes extruded and intruded melt products within continental crust are still not accurately resolved using geophysical methods. Here we investigate budget alongside South Atlantic margins, onset seafloor spreading, high-quality seismic reflection profiles to estimate oceanic crustal thickness. We show that, along ~ 75% length...
Abstract A high heat‐flow (∼900 mW m −2 ) has been observed over a volcanic structure at the Ocean‐Continent Transition in Eastern Gulf of Aden (Oman margin). The anomaly is superposed to progressive increase across margin and can be interpreted either by (1) heat refraction, (2) fluid discharge or (3) cooling magma. two first explanations cannot ruled out definitely modelling analysis, but require unlikely thermal conductivity permeability values. third one implies that latest activity...
Syn-rift sequences, breakup unconformities and magnetic anomalies have been widely used to date rifting. However, it is generally accepted that rift systems are diachronous, both along dip strike, the rifting processes complex difficult date, in particular at magma-poor rifted margins. Therefore, new approaches need be developed In our study we use stratigraphic record of vertical movements a specific event its propagation. this work, focus on two origins uplift during First, necking...
Abstract The offshore drilling operation is supported by specialized mud that contains barite to increase its density. Often, falls out of suspension within the mud, between time offtake Offshore Supply Vessel (OSV) reaching dockside. Although tanks are equipped with circulation pumps ensure remains in suspension, large volume could still be lost during tank cleaning operation. This paper describes development and testing a robotic enhanced recovery (REBR) system aims identify, qualify,...
