Unlocking Earth’s inner secrets in deep time using palaeointensities. The geomagnetic field, generated in Earth's liquid outer core, provides Earth's biosphere and atmosphere with a critical protective shield from the bombardment of the solar wind. However, we still know little about the evolution of the geomagnetic field or the deep-time secrets it keeps. This project aims to study the varying intensity of the geomagnetic field during Earth’s middle life. The results will help decipher how the ....Unlocking Earth’s inner secrets in deep time using palaeointensities. The geomagnetic field, generated in Earth's liquid outer core, provides Earth's biosphere and atmosphere with a critical protective shield from the bombardment of the solar wind. However, we still know little about the evolution of the geomagnetic field or the deep-time secrets it keeps. This project aims to study the varying intensity of the geomagnetic field during Earth’s middle life. The results will help decipher how the Earth’s core responded to evolving tectonic and dynamic systems, including the supercontinent cycles, and when Earth’s solid inner core initiated. Such knowledge will help us to better understand how the Earth System evolved as a whole, and how such an evolution has led to the present day life and environment on Earth.Read moreRead less

How the Earth works - toward building a new tectonic paradigm. How the Earth works - toward building a new tectonic paradigm: This fellowship project aims to build on the latest technological and conceptual advances to establish the patterns of Earth evolution, and use this information to examine a ground-breaking geodynamic hypothesis which links cyclic plate aggregation and dispersion to deep Earth processes.

How the Earth works - toward building a new tectonic paradigm: This fellowship project aims to build on the latest technological and conceptual advances to establish the patterns of Earth evolution, and use this information to examine a ground-breaking geodynamic hypothesis which links cyclic plate aggregation and dispersion to deep Earth processes. Half a century after the inception of plate tectonics theory, we are still unsure how the Earth 'engine' works, particularly the forces that drive plate tectonics. The project involves extensive national and international collaboration to potentially create a paradigm shift in our understanding of global tectonics, and hopes to contribute to an understanding of the formation and distribution of Earth resources to provide a conceptual framework for their exploration.Read moreRead less
Mapping mineral systems of deep Australia. We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration su ....Mapping mineral systems of deep Australia. We aim at enabling mineral resource discoveries by calibrating geophysical surveys using geochemical and petrophysical properties measured on mantle samples brought to the surface by recent volcanoes. National geophysical surveys deliver images of geophysical gradients in the deeper part of the Australian continent. The interpretation of these gradients in geological terms and in terms of economic mineral systems is the key to unlock deep exploration success. This project will turn Australia’s investment in National geophysical surveys into new discoveries of base metals. The benefit stems from enabling the transition to a clean economy which requires a much broader range of critical minerals and a larger quantity of base metals.Read moreRead less
