Understanding the Deep Carbon Cycle from Icehouse to Greenhouse Climates

16 May, 20178 May, 2017 by Ruken

Sydney Research Excellence Initiative grant (2017-2018) Research area, key questions, significance, and innovation. The planet is experiencing a major transition from an icehouse climate, one dominated by permanent continental ice sheets at high latitudes, to a greenhouse climate that favours ice-free conditions. Although part of the deglaciation trend is influenced by a natural orbital cycle, … Read more…

Gondwanaland extension, breakup and continental margin evolution

26 July, 20151 June, 2014 by Michael Chin

Project Summary
Plate reconstruction models for the rifting and separation of Gondwanaland’s conjugate margins continue to be poorly constrained in detail. We propose to develop a new plate model for the entire Indian ocean by synthesizing old and new geological and geophysical data using our plate tectonic software system. We will test continental fit reconstruction hypotheses and alternative models for the early opening of the Indian Ocean by using a variety of reconstructed gridded and vector data sets. … Read more…

Understanding the deep driving forces of Earth’s large-scale topography through time

4 October, 201610 September, 2013 by Michael Chin

Project Summary
Continents and sedimentary basins through time record fundamental Earth system cycles, reflecting environmental change, migration of fauna and flora and shifting coastlines. It was originally thought that successive advances and retreats of shallow inland seas mainly reflect global sea level variations (eustasy). It is now well known in principle that large-scale surface morphology such as the high topography of the East African Rift, the low-lying Amazon River Basin and the southwest to northeast tilt of the Australian continent are strongly controlled by processes deep within the Earth, but progress has been slow in quantifying the magnitude and time-dependence of these relationships. … Read more…

Australian Paleo-stress map project

4 February, 20191 July, 2012 by Michael Chin

Using 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.
