Australian Paleo-stress map project

by

Fig12_0Ma-6Ma_asmUsing the engineering finite element modelling software package ABAQUS we have modelled the horizontal compressive stress of the Indo-Australian plate for time periods dating from the mid-Cretaceous. This work was carried out as part of the Tectonic Reactivation and Palaeo-Stress (TRAPS) Linkage project in collaboration with Shell, BHP Billiton,Woodside Petroleum and SANTOS in order to create a framework for predicting the tectonic reactivation of faults through time.

Testing absolute plate reference frames and the implications for the generation of geodynamic mantle heterogeneity structure

by

Shephard 2012 agegrids vels 140-1Absolute reference frames are a means of describing the motion of plates on the surface of the Earth over time, relative to a fixed point or frame. Multiple models of absolute plate motion have been proposed for the Cretaceous-Tertiary period, however, estimating the robustness and limitations of each model remains a significant limitation for refining both regional and global models of plate motion as well as fully integrated and time dependent geodynamic models. Here, we use a novel approach to compare five models of absolute plate motion in terms of their consequences for forward modelled deep mantle structure since at least 140 Ma. … Read more…

Dynamic topography and anomalously negative residual depth of the Argentine Basin

by

Shephard 2012 Argentine Basin-1A substantial portion of Earth’s topography is known to be caused by the viscous coupling of mantle flow to the lithosphere but the relative contributions of shallow asthenospheric flow versus deeper flow remains controversial. The Argentine Basin, located offshore of the Atlantic margin of southern South America, is one of the most anomalously deep ocean regions as it is significantly deeper than its age would suggest. … Read more…

Constraining the Jurassic extent of Greater India: Tectonic evolution of the West Australian margin

by

2011GC003919-p1a-1We present the Indian Ocean plate tectonic model accompanying the study of Gibbons et al., (2012). This work details the first regional-scale tectonic model of the breakup of East Gondwana. Our model shows that the breakup of East Gondwana started with the migration of a continental sliver, Argoland, in the Late Jurassic and was followed by breakup between Greater India and Australia-Antarctica in the Early Cretaceous, involving spreading reconfigurations, which left several sunken continental plateaus of Indian crust on the Australian plate. New evidence from seafloor off northwest Australia also shows that the majority of Greater India reached only about halfway up the West Australian margin, to the Wallaby-Zenith Plateaus. … Read more…

An open-source software environment for visualizing and refining plate tectonic reconstructions using high-resolution geological and geophysical data sets

by

GSA Today Cover-1We describe a powerful method to explore spatio-temporal relationships within geological and geophysical data sets by analyzing the data within the context of tectonic reconstructions. GPlates is part of a new generation of plate reconstruction software that incorporates functionality familiar from GIS software with the added dimension of geological time. Here we use GPlates to reconstruct geological terranes, geophysical grids, and paleomagnetic data within alternative tectonic models of the assembly of Western Australia and the configuration of Rodinia. With the ability to rapidly visualize a diverse range of geological and geophysical constraints within different reconstructions, users can easily investigate the implications of different tectonic models for reconciling a variety of observations and make more informed choices between different models and data. … Read more…

Insights on the kinematics of the India-Eurasia collision from global geodynamic models

by

Image 002We present the input plate motion models and results from the study by Zahirovic et al. (2012) on the India-Eurasia collision using linked kinematic and geodynamic models.

Two end-member scenarios of the India-Eurasia collision were tested. The conventional model invokes long-lived Andean-style subduction along southern Eurasia until continental collision between a maximum extent Greater India and Lhasa at ~60 Ma. … Read more…
