Generalities Active continental margins, i.e., when an oceanic plate subducts beneath a continent, represent about two-thirds of the modern convergent margins. Their cumulated length has been estimated to 45,000
Thus, our data suggest that the southeastern margin of the NCC might have formed in a tectonic setting characterized by a late Neoarchean active continental margin, and was related with oceanic slab subduction, as also proposed for the northern and southern margins of the NCC by various authors ...
This fault is in fact a faulted ramp anticline, which is cored by reddish Miocene continental beds. The cumulative slip on this fault produced scarps on the flat-topped surfaces of the Quaternary alluvial fans that are overlying the Miocene red beds (Fig. 8). Scarp heights increase with the...
The study area is located at the margins of two hydrogeological systems with the following main flow directions: (1) The northern Golan Heights system that flows from the flanks of Mt. Hermon towards the Yarmouk (Arad and Bein1986; Roded et al.2013; Starinsky et al.1979) and (2) The ...

The dynamics and melt sources for crustal growth at active continental margins are analyzed by using a 2D coupled petrological鈥搕hermomechanical numerical model of an oceanic-continental subduction zone. This model includes spontaneous slab retreat and bending, dehydration of subducted crust, aqueous ...
Continental margins: transformCrustal structureOceanic transform and fracture zone processesThe southern boundary of the Cayman Trough in the Caribbean is marked by the Swan Islands transform fault (SITF), which also represents the ocean–continent transition of the Honduras continental margin. This is ...
The rest of the continental regions have significantly lower contributions to the global BA. In the temperate region of North America (TENA) some fire activity can be noted in the agricultural areas located at the Mississippi's alluvial plain and Central Great Planes, followed by the boreal areas...
Cold seeps are widespread seafloor habitats that are characterized by the upward advection of methane and other hydrocarbons from the oceanic subsurface to the seafloor. They are found scattered at continental margins and plate boundaries. Cold seeps are separated by large expanses of energy-limited ...
