A comprehensive evaluation of the structural framework and tectonic evolution of Southeast Asia. The report builds a fundamental structural and tectonic framework based on data, including Getech’s best available gravity and magnetic data. The result is a detailed, kinematically realistic structural map and a new and original regional plate tectonic model.
Scientific rigour is the foundation of this report. Structural mapping is constrained against data; plate modelling is in turn constrained by these structures. Additionally, the plate model is developed in the context of Getech’s Global Plate Model to eliminate boundary effects.
“The result is a detailed, kinematically realistic structural map and a new and original plate tectonic model.”

This Regional Report investigates…
…the opening history of the South China Sea: extrusion tectonics versus slab pull.
…the redefinitions of major plate boundaries in the region, e.g. does Borneo really rotate as a single plate?
…neotectonics as an constraint to plate modelling.
…solutions to previous attempts at plate modelling in the region, e.g. the space problems caused by the rotation of Sulawesi and subduction of the Celebes Sea.
…the crustal extension as constrained by 2D gravity and magnetic profile modelling.
