The metamorphic evolution of an ancient accretionary prism in the southern zone of the Damara Belt in Namibia

, 2013
The Southern Zone of the Damara Belt in central Namibia has an apparent stratigraphic thickness that exceeds 100 km and is comprised of highly strained, metamorphosed clastic sedimentary rocks that are intercalated with slices of metamorphosed basalt and

Thermal history of Early Jurassic eclogite facies metamorphism in the Nagaland Ophiolite Complex, NE India: New insights into pre-Cretaceous subduction channel tectonics within the Neo-Tethys

, 2019
Eclogite from two locations in a fossil accretionary complex now exposed in Nagaland, NE India, at the northern end of the Indo-Myanmar ranges, provides the oldest evidence for Neo-Tethyan subduction along the Yarlung-Tsangpo suture zone.

Internal structure of an ancient analogue of an erosive subduction channel: the Subligurian Units of the Northern Apennines, Italy

, 2007
The Subligurian Units –SLU- were involved in the Apennine subduction system starting from the middle Eocene. At the time the SLU were part of the Ligurian prism forming the frontal portion of the European margin. The present geometric position of the SLU,

Structural Evolution of the Eastern Nankai Trough accretionary prism, Central Japan—Subduction of Trough-Parallel Seamount Chains

Progress in Earth and Planetary Science
The Nankai Trough, offshore of Southwest Japan, represents a plate subduction zone where a long history of devastating mega-earthquake and tsunami events has been best documented.

Exhumation Processes in Oceanic and Continental Subduction Contexts: A Review

, 2009
Although the exhumation of high pressure (HP) and ultrahigh pressure (UHP) rocks is an integral process in subduction, it is a transient process, likely taking place during the perturbation in subduction zones.

Subduction zone metamorphism: Timescales and emergence in the geological record [PDF]

, 2021
Eclogites and blueschists are the primary recorders of processes that occur within subduction zones. Their mineralogy can be used to determine their pressure-temperature-time (P–T–t) evolution during burial to mantle depths, which in turn illuminates ...

Rheology modification in a subduction channel due to eclogite facies metasomatism (Rocky Beach Metamorphic Mélange, Port Macquarie, Australia)

The rheological properties of the interface between the down-going and overriding plates in subduction zones provides insight into how plate convergence is accommodated and the controls on seismic and aseismic slip.

Differences in Mesozoic–Cenozoic Structural Deformation Between the Northern and Southern Parts of the East China Sea Shelf Basin and Their Dynamic Mechanisms

Journal of Marine Science and Engineering
The East China Sea Shelf Basin (ECSSB) and its adjacent areas, as key regions of the ocean–continent transition zone, have been affected by multiple complex plate collisions, subduction, and back-arc tension since the Mesozoic Era.
