A unified model for the closure dynamics of ancient Tethys constrained by Geodesy, Structural Geology, Argon Geochronology and Tectonic Reconstruction

Project: Research

Project Details

Description

We aim to use geodesy, structural geology and argon geochronology to develop a unified self-consistent dynamic planetary model for closure of the (once 12000 km across) ancient Tethys Ocean, from deep time until the present. Movements in the tectonic reconstruction will be constrained by the timing of event sequences we measure. GPS will provide constraints on time zero motions. Links between plate dynamics and evolving plate geometry will be explored by simulation and modelling using NCRIS AuScope SAM software. We will show how mechanical torque balance alters in the planetary assemblage of lithospheric plates during accretion events, focussing on the role of indentors, and how subduction zone roll-back affects adjacent foundering basins.
