Neogene plate tectonic reconstructions and geodynamics of North Island sedimentary basins: Implications for the petroleum systems [PDF]
Although the modern Australia-Pacific plate boundary through New Zealand is relatively straight, there have been significant changes in its geometry during the Neogene. Within the North Island sector there has been a fundamental transition from an Alpine

Contribution of ultramafic rocks in central Sanandaj-Sirjan zone to the characterizing of physio-chemical condition during initiation of subduction [PDF]
In the central part of the Sanandaj-Sirjan zone, there is an ultramafic rock exposure (hornblendite and pyroxenite) adjacent to Molataleb felsic complex completely located between Azna and Aligoodarz towns.

A tensile, flexural model for the initiation of subduction [PDF]
We argue that subduction may be initiated at passive continental margins without shortening the lithosphere. Overcoming the lithosphere's high compressive strength requires special circumstances, and these make it difficult to explain the nearly complete recycling of old sea-floor.

Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Subduction initiation and the rise of the Shillong Plateau
Abstract Discrepancies between geodetically and geologically estimated thrust fault slip rates are generally viewed as a methodological problem. Even when slip rate is steady over geological time, a discrepancy may exist because each method is sensitive to different deformation processes.

A numerical study of the dynamics of subduction [PDF]
The mechanics and dynamics of subduction have been studied using 2-D finite element analysis. Two finite element formulations have been employed; one formulation for Newtonian viscous flow and one formulation for linear elasticity and viscoelasticity ...

Structure and Propagation of Mesoscale Cyclonic Eddies in the Brazil–Malvinas Confluence
Between 1993 and 2022, 1386 cyclonic eddies were identified in the Brazil–Malvinas Confluence, one of the most energetic regions of the South Atlantic. While most eddies dissipated locally, a smaller number of individuals, more energetic, and longer lived propagated predominantly south‐westward and north‐eastward, driven by topographic constraints and ...

Subduction initiation in oceans is key to understanding regional and global plate tectonics and ocean basin dynamics; however, its genetic mechanism is still enigmatic.

Understanding the formation of new subduction zones is important because they have been proposed as the main driving mechanism for plate tectonics and they are crucial for geochemical cycles on Earth.
