Scanning electron microscopy is a basic analytical tool for imaging surfaces of natural and synthetic materials and identification of nanometre-scale features and their compositions. At the University of Tasmania, it supports four of our six designated priority research themes: Antarctic and Marine Studies, Environment, Frontier Technologies, and Sustainable Primary Production. Our research depending on this technique includes many fundamental and applied topics from a wide range of disciplines, such as developing portable detection devices for explosives, finding more efficient and sustainable ways to explore for ore, investigating the effects of climate change on marine ecosystems and improving salinity and drought tolerance of crops.Read moreRead less

This proposal aims to replace an existing 12-year old conventional electron microprobe with a state-of-the art field emission electron microprobe instrument capable of in-situ, low-level, quantitative non-destructive chemical analysis, and mapping of element distribution and texture at sub-micron resolution. This would establish new research strengths in the field of earth and materials science. In particular, it may improve efficiencies of discovery and recovery of ore deposits and develop environmentally friendly processes for waste disposal. Read moreRead less

Summary
A new generation fast mapping Raman system. This fast-imaging Raman facility will give researchers at the University of Tasmania a new tool to rapidly analyse the chemical properties of a wide range of materials in a non destructive way. It will complement other instrumentation and support a diverse range of research areas addressing several national research priorities.
Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the ....Pyrite: a deep-time capsule of ocean chemistry and atmosphere oxidation. Surprisingly little is known about trace element trends in past oceans, even though these data are vital for interpreting the evolution of the Earth's atmosphere, evolutionary pathways of marine life and cycles of major mineral deposits. Using laser-based analysis of sedimentary pyrite in deep marine rocks, this project aims to produce, for the first time, temporal variation curves for 25 trace elements in seawater over the last 3.5 billion years. Preliminary research has validated the technique and demonstrated major changes in certain trace elements over geologically short periods. Outcomes will assist the minerals industry in the discovery of new deposits of zinc, copper, gold and iron ore in Australia.Read moreRead less
Assessment of the potential consequences of large-scale eradication of rice grass from the Tamar Estuary, Tasmania. Introduced Rice grass has trapped large volumes of intertidal sediment, yet reduced amenity values of the Tamar Estuary, transforming beaches into muddy rice grass meadows, threatening aquaculture industries, and silting up coastal developments. This project will investigate the consequences of rice grass eradication, by determination of sediment volume trapped, contaminants contai ....Assessment of the potential consequences of large-scale eradication of rice grass from the Tamar Estuary, Tasmania. Introduced Rice grass has trapped large volumes of intertidal sediment, yet reduced amenity values of the Tamar Estuary, transforming beaches into muddy rice grass meadows, threatening aquaculture industries, and silting up coastal developments. This project will investigate the consequences of rice grass eradication, by determination of sediment volume trapped, contaminants contained, and monitoring of processes active after removal. The outcomes of this research will enable informed decisions on management of the Tamar rice grass infestation, and provide an understanding the impacts of large scale eradication to management authorities of similar infestations in Victoria, New Zealand, Europe, China and the USA.Read moreRead less
Volcanology of voluminous felsic lavas. Eruptions of voluminous lavas (>100km3)have occurred throughout geological time but not in recorded human history. These lavas are a major part of very large volcanic areas that form the continents. Excellent examples have been identified in the Gawler Range Volcanics, South Australia. Little is known about the eruption mechanisms and yet these events are the key to understanding large-scale melting processes deep in the Earth and continent formation. This ....Volcanology of voluminous felsic lavas. Eruptions of voluminous lavas (>100km3)have occurred throughout geological time but not in recorded human history. These lavas are a major part of very large volcanic areas that form the continents. Excellent examples have been identified in the Gawler Range Volcanics, South Australia. Little is known about the eruption mechanisms and yet these events are the key to understanding large-scale melting processes deep in the Earth and continent formation. This research will use field data from one of the South Australian examples to constrain the nature and position of the source volcanic centre and to clarify outflow mechanisms.Read moreRead less

Results from drilling within Australia's marine jurisdiction will give understanding of the oceans' state under past climates through high resolution records of the range of oceanographic and biological responses to climate change, the role of the deep biosphere in shaping oil and gas deposits, hydrothermal and igneous processes involved in ore genesis, and enhanced understanding of some of the world's largest earthquake- and tsunami-generating processes.

Tectonic paradox of the E margin of the Australian plate, 120 - 45 Ma. Available geological evidence indicates that massive extension of continental crust occurred from 120-45 million years ago at the eastern margin of the Australian plate. In contrast, global plate movement models indicate that there was convergence between the Pacific and Australian plates, implying subduction and island arc magmatism. We propose a marine research expedition to dredge rocks from scarps of the submarine ridges ....Tectonic paradox of the E margin of the Australian plate, 120 - 45 Ma. Available geological evidence indicates that massive extension of continental crust occurred from 120-45 million years ago at the eastern margin of the Australian plate. In contrast, global plate movement models indicate that there was convergence between the Pacific and Australian plates, implying subduction and island arc magmatism. We propose a marine research expedition to dredge rocks from scarps of the submarine ridges east of Australia. Geochemical signatures and dating of the dredged rocks should elucidate the geological evolution of this region, improve our understanding of eastern Australian geology, and better define Australia's Maritime Jurisdiction Zone along the eastern seaboard.Read moreRead less
A detrital apatite archive to track crustal growth. This project will establish apatite as a new tool to study the evolution of the continental crust. The crust shaped the composition of the atmosphere and the oceans with consequences for the evolution of life through the availability of oxygen and nutrients. However, when and how the continental crust was generated remains a core question. Current models for continental crust development rely on the mineral zircon.

The crust shaped the composition of the atmosphere and the oceans with consequences for the evolution of life through the availability of oxygen and nutrients. However, when and how the continental crust was generated remains a core question. Current models for continental crust development rely on the mineral zircon. However, zircons only record the history of evolved rocks. To address this bias we will use the mineral apatite which forms in less evolved rocks. We will develop a detrital apatite database of Pb-Nd (model) ages and integrate this with the zircon record to provide a more holistic description for how our planet developed.Read moreRead less
