Bathymetry of Mariana trench‐arc system and formation of the Challenger Deep as a consequence of weak plate coupling

  author={Zohar Gvirtzman and Robert J. Stern},
The Challenger Deep in the southernmost Mariana Trench (western Pacific Ocean) is the deepest point on the Earth's surface (10,920 m below sea level). Its location within a subduction trench, where one plate bends and descends below another, is not surprising. However, why is it located in the southernmost Mariana Trench and not at its central part, where the rate of subduction is higher, where the lithosphere is the oldest (and densest) on the Earth, and where the subducted lithosphere pulling… 

Docking and subduction of the West Pacific seamounts along the Mariana Trench and their effects

The Mariana Trench is located at the edge of the West Pacific Plate, with a lot of large aseismic ridges lying there. These seamounts significantly affect the trench morphology and topographic change

A precise bathymetric map of the world’s deepest seafloor, Challenger Deep in the Mariana Trench

Data from three bathymetric surveys by R/V Kairei using a 12-kHz multibeam echosounder and differential GPS were used to create an improved topographic model of the Challenger Deep in the

Geodynamic evolution of a forearc rift in the southernmost Mariana Arc

The southernmost Mariana forearc stretched to accommodate opening of the Mariana Trough backarc basin in late Neogene time, erupting basalts at 3.7–2.7 Ma that are now exposed in the Southeast

Nature and distribution of slab‐derived fluids and mantle sources beneath the Southeast Mariana forearc rift

Subduction zone magmas are produced by melting depleted mantle metasomatized by fluids released from the subducted slab. In most subduction zones, formation of backarc basin (BAB) and arc magmas

Trench topography in subduction zones: A reflection of the plate decoupling depth

Subduction of lithospheric plates produces narrow, linear troughs (trench) in front of the overriding plates at the convergent boundaries. The trenches show a wide variation in their topographic

Basaltic volcaniclastics from the Challenger Deep forearc segment, Mariana convergent margin: Implications for tectonics and magmatism of the southernmost Izu–Bonin–Mariana arc

Convergent margin igneous activity is generally limited to 100–200 km from the trench except where spreading ridges are subducted or in association with Subduction‐Transform Edge Propagators (STEP

Peridotites from a ductile shear zone within back‐arc lithospheric mantle, southern Mariana Trench: Results of a Shinkai 6500 dive

Two N–S fault zones in the southern Mariana fore arc record at least 20 km of left‐lateral displacement. We examined the eastward facing slope of one of the fault zones (the West Santa Rosa Bank

How the Mariana Volcanic Arc ends in the south

The southern Mariana Arc–Trench system is rapidly deforming, resulting in unusual interactions between arc and back‐arc basin (BAB) magmatic systems. New geochemical data for volcanoes in this region



Morphology and origin of the Challenger Deep in the Southern Mariana Trench

A high resolution bathymetry survey reveals the detailed morphology of the Southern Mariana Trench. Distinct right stepping, N80°E trending en echelon deeps were found on the trench bottom within the

Volcanoes of the southwestern extension of the active Mariana island arc: New swath‐mapping and geochemical studies

Until recently it was thought that the volcanoes of the Mariana island arc of the western Pacific terminated at Tracey Seamount at ∼ 14°N immediately west of Guam. Sea floor mapping in 1995 shows a

Partial detachment of a lithospheric root under the southeast Carpathians: Toward a better definition of the detachment concept

The southeast corner of the Carpathian Mountains (Romania) provides a unique opportunity to study the very final and shortlived stage of plate convergence when a piece of subducted lithosphere

Seafloor Spreading in the Mariana Trough: Results of Leg 60 Drill Site Selection Surveys

A detailed geophysical and geological survey of the Mariana Trough, an actively extensional back-arc basin, was conducted in 1976 and 1977 to provide data for selection of drilling sites for DSDP Leg

Evolution of the Mariana Convergent Plate Margin System

The Mariana convergent plate margin system of the western Pacific provides opportunities for studying the tectonic and geochemical processes of intraoceanic plate subduction without the added

Plate detachment, asthenosphere upwelling, and topography across subduction zones

This study analyzes the topography across subduction zones, considering the separate contributions of the crust and the mantle lithosphere to the observed surface elevation. We have found a

Geophysical characteristics of the southern Mariana Trough, 11°50'N-13°40'N

Despite slow opening rates generally inferred for the Mariana Trough, the southernmost part of the basin has “fast spreading” geophysical and morphologic characteristics that are unlike the features

The formation of Mount Etna as the consequence of slab rollback

Mount Etna, the largest volcano in Europe, lies close to the subduction-related Aeolian magmatic arc but shows no trace of subducted material in its magmas. Mount Etna is also situated on continental
