Morphology and Structure of the Southern Part of the New Hebrides Island Arc System
نویسنده
چکیده
1) An accretionary prism with a constant width of approximately 75 km does exist; 2) The morphology of this prism varies rapidly along the arc and is linked, firstly to the morphology and structure of the upper part of the dipping plate and, secondly to the presence of volcanic island acting as sediment sources; The island arc and its connecting structural features such as troughs at the rear of the arc, are disrupted by transversal discontinuities, the largest of which could be related to fractures of the oceanic crust of the dipping plate. makes it possible to define the different structural units:

Large - scale deformation associated with ridge subduction
S U M M A R Y Continuum models are used to investigate the large-scale deformation associated with the subduction of aseismic ridges. Formulated in the horizontal plane using thin viscous sheet theory, these models measure the horizontal transmission of stress through the arc lithosphere accompanying ridge subduction. Modelling was used to compare the Tonga arc and Louisville ridge collision wi...

متن کاملEcological classification of southern intertidal zones of Qeshm Island, based on CMECS model
The “Coastal and Marine Ecological Classification Standard (CMECS)”, a new approach to ecological classification, was applied to 122 km of the southern intertidal zone of Qeshm Island located the Hormouz Strait - the Persian Gulf. Two components of this model, Surface Geology (SGC) and Biotic Cover (BCC) were used. Considering the extent and geomorphological alternations of the covered area, 12...

The study investigated the stomach contents of Indian mackerel (Rastrelliger kanagurta) from the southern part of Qeshm Island in the Persian Gulf from April 2016 through March 2017. The food and feeding behavior of R. kanagurta with a fork length of 17.8 to 22.5 cm was assessed from the analysis of gut contents. The frequency of occurrence and numeric methods were used for stomach content anal...

Ophiolites of the Zagros orogenic belt are part of the Tethys ophiolites, because of their geographical locations and link the Middle East ophiolites and other Asian ophiolites (e.g. Pakistani and Tibetan) to the Mediterranean ophiolites (e.g. Troodos , Greek and East European). The nature of the Harsin- Sahneh ophiolite (Kermanshah) traditionally identified as one of the Mesozoic southern bran...
