Tectonics and Earth Systems
The Tectonics and Earth Systems (TES) Group explores how deformation of the solid earth over deep time built a human-habitable, resource-rich planet.
The Tectonics and Earth Systems Group is a part of the Mawson Centre for Geoscience and its research spans the Institute for Minerals and Energy Resources (IMER) and the Environment Institute.
TES Group members are geologists and geochemists, and our aim is to develop an evolving model of the world where every aspect is testable and mutable.
We use geochronology, thermochronology, structural geology, geochemistry, igneous geology and sedimentology to unravel the tectonic geography of a region through deep time.
Our work is data focussed and built from the rock record. As such we work with geochemical proxies for tectonic processes, redox, salinity, productivity, erosion and hydrothermal activity, many of which are pioneering and developmental.
We are also investigating new, rapid, accurate dating techniques, such as laser-ablation analysis of Rb–Sr and K–Ca isotope systems via plasma mass spectrometry (see also our Metal Isotope Group) and are grappling with data analytical approaches to apply to the sizable and diverse data we generate and interpret.
By combining these studies, we attempt to reconstruct the past continents and oceans of the world in a full plate-tectonic manner; focussing on the last 2 billion years of earth history, when we consider plate tectonics operated in a similar manner as it does today.
From these novel, full-earth, reconstructions we strive to quantify feedbacks between geosphere phenomena (such as mountain belt topographic evolution, ocean basin connectivity, and rift development), chemistry of the atmosphere/hydrosphere and the development of the biosphere.
Key research areas
- Constraining full-plate topological reconstructions of the world from 2 Ga to present using the global rock record
- Reconstructing ancient topography by deconvolving the rock record in ancient orogens and successor sedimentary basins
- Understanding the evolving tectonic setting, water chemistry, ecology and resource endowment of major Proterozoic and Palaeozoic Basins
- Deconvolving the tectonic complexity of pre-collision active margins in ancient orogens
- Understanding the solid earth controls on transitions in the supra-geosphere earth
- Developing novel laser-based isobaric geochronometers (e.g. Rb–Sr and K–Ca)
