Grant has degrees in both Chemistry and Earth Sciences and is presently focused on assessing the environmental impact of fluid-rock interactions on groundwater chemistry. This entails a variety of rock characterisation techniques (elemental, mineralogical, petrophysical), benchtop sequential extraction experiments, and pressure vessel experiments that mimic in-situ conditions deep underground, with data then fed into geochemical modelling software. The analytical equipment that Grant has operated to achieve his research outcomes includes ICP-MS, ICP-OES, SEM-EDS, Microprobe, XRF, Synchrotron XFM beamline, Petrographic Microscopes (both scanning and standard), Gas Permeameter, Helium Pycnometer, Pressure Vessels, etc. Grant also has an active interest in the geological storage of carbon dioxide, both via injection into deep geological formations and direct atmospheric capture facilitated by rock weathering to form stable carbonate rocks (mineral trapping of CO2). In the past, Grant has studied natural carbonate mineralisation (both veins and cement) throughout the Great Artesian Basin, to explore the variety of natural conditions that promote the transformation of CO2 into minerals. Early in his research career, Grant participated in paleo-climate research projects that involved botanically describing and assessing the cell morphology of fossil woods, coal petrography, studying coral cores, and picking foraminifera recovered from the sea floor.

I am a sedimentary geochemist, and I work on a variety of problems in sedimentary geology, paleoclimate, and basin analysis through the use of petrology, elemental geochemistry, and stable isotope geochemistry. I run the Carbonate Research and Geochemistry group at UQ, where we have a variety of facilities for sample petrology, carbonate precipitation under controlled environmental conditions, and geochemical analysis. Several active and potential research areas are outlined below.

Clumped Isotope Reordering and Basin Analysis

Currently we are investigating clumped isotope reordering - the change that occurs in a sample's clumped isotope value as a result of solid-state diffusion of 18O and/or 13C within the crystal lattice of a carbonate mineral. This is important to understand for two reasons. First, if we are trying to get accurate paleoclimate data using clumped isotope paleothermometry, we need to know what conditions (burial depth and heating) allow for primary signals, and under which conditions the primary signal is lost. Second, if we know the kinetics of clumped isotope reordering, we can then apply that knowledge to understand past heat flow in a basin. Combined with a stratigraphic column and burial history for a body of rock, we can reconstruct geothermal gradients, and evaluate tectonic/basin models based on whether they could produce the required heat flux to match observed clumped isotope values. Areas of active research include precipitating model carbonates in the lab to study the effects of different cations, burial diagenesis, and applications to sediment hosted ore bodies/other economic systems.

Carbonate Sedimentation and Diagenesis

Carbonate sedimentation and diagenesis is one of our active research areas, with a focus on combining laboratory experiments, modern analogues, and ancient rocks to understand the long term evolution of carbonates and other sediments. Clumped isotopes are useful here as it turns out they do record the temperature of formation in most cases, and can be applied to a variety of problems, such as contemporary dolomite formation, or the temperature of formation of otherwise engimatic carbonate textures, such as 'beef' calcites. We are also interested in the sedimentation and diagenesis of carbonate reefs, such as the geological history of the Great Barrier Reef, and are currently studying the halogen composition of carbonates, reef rocks and corals, and oceanic sediments in general.

Paleoclimate Research

I have been interested in paleoclimate since I took my first geology class at Northwestern. Since then, I've worked on a variety of timescales and systems, but the common theme has been the application of stable isotopes and clumped isotopes. Clumped isotopes are a wonderful tool for paleoclimate research in situations where the water oxygen isotope composition is uncertain, such as terrestrial and lacustrine settings, deep time where even the oxygen isotopic composition of the ocean is uncertain, or even in (relatively) more modern systems that might be affected by runoff or glacial meltwater. Active projects and areas of interest include Holocene climate change/ENSO, Southern Ocean Cenozoic paleoclimatology, and 'bizzare' climate events such as the Neoproterozoic Snowball Earth glaciations.

Dr Mansour Edraki is a geo-environmental scientist specialising in the field of inorganic geochemistry. He joined UQ in 2000 following completion of his PhD at University of New England. Prior to that, and before immigrating to Australia, he was a lecturer in earth sciences. Since joining UQ, Dr Edraki has focused on developing innovative techniques for understanding and predicting geochemical processes which underpin sustainable management of mine waste and mine water, particularly acid and metalliferous drainage. Mansour’s research has direct applications for the resources and energy industries and the impact of his work is evident in a continuous flow of industry-funded projects in the last decade. Dr Edraki has initiated research collaborations in many international locations including Indonesia (South Kalimantan and Freeport), Iran (Mehdiabad Zinc) Papua New Guinea (Ok Tedi), Philippines (USEP and Mindanao Development Authority), Korea (MIRECO and KIGAM), Peru (INGEMET), and Chile (Fundación Chile, Universidad de Concepción).

Science and technology of ecological engineering of ferrous and base metal mine tailings (e.g., magnetite tailings, bauxite residues (or red mud), Cu/Pb-Zn tailings) into functional technosols and hardpan-based soil systems for sustainable tailings rehabilitation: geo-microbial ecology, mineral bioweathering, geo-rhizosphere biology, technosol-plant relations in mined environments. Championing nature-based solutions to global mine wastes challenges.

Longbin Huang is a full professor and a Program leader in The University of Queensland, leading a research program of "Ecological Engineering in Mining" to develop naure-based methdology and technology, for assisting the world's mining industry to meet the global tailings challenge. Driven by the passion to translate leading knowledge into industry solutions, Longbin has pioneered transformative concepts and approach to tackle rehabilitation of mine wastes (e.g., tailings, acidic and metalliferous waste rocks). Recent success includes the "ecological engineering of Fe-ore tailings and bauxite residue" into soil, for overcoming the topsoil deficit challenge facing the mining industry. Scaled up field trials have been going on to deliver the much-needed technology into field operations. Long-term and multi-site based field trials have demonstrated for the first time, the field-feasibility to accelerate nature-based soil formaiton processes for developing tailings into adaptive and sustainable soil (or technosol) capable of sustaining plant community growth and development (https://www.youtube.com/watch?v=6VzfiWL-8UI&t=4s).

The program consists of a group of researchers with leading knowledge and research skills on: soil/geo-microbial ecology, environmental mineralogy, bioweathering of minerals, native plant rhizosphere (micro)biology, soil-plant relations, and environmental materials (such as biochar and environmental geopolymers). It aims to deliver transformative knowledge and practices (i.e., technologies/methdologies) in the rehabilitation of mine wastes (e.g., tailings, mineral residues, spoils, waste rocks) and mined landscapes for non-polluting and ecologically and financially sustainable outcomes.

In partnership with leading mining companies, Longbin and his team have been focusing on developing game-changing knowledge and technologies of tailings valorisation for achieving non-polluting and ecologically sustainable rehabilitation of, for example, coal mine spoils and tailings, Fe-ore tailings, bauxite residues (or red mud), and Cu/Pb-Zn tailings. Leading the global progress in bauxite rehabilitation, Longbin and his team are currently taking on field-scale research projects on bauxite residue rehabilitation technologies at alumina refineries in Queensland (QAL- and Yarwun refineries) and Northern Territory (Gove refinery).

Longbin's industry-partnered research was recognised in 2019 UQ’s Partners in Research Excellence Award (Resilient Environments) (Rio Tinto and QAL).

Julie’s research is mainly focussed on gas-water-rock core reactivity at reservoir conditions using experimental, field, and geochemical modelling techniques. Recent projects have been in the application of carbon dioxide geological storage in which CO2 is captured and stored in formations generally contained by low permeability cap-rock. The safe containment of the injected CO2 and the potential changes to rock porosity, permeability, and water quality should be determined. Recent and current projects with a focus on a demonstration site in the Surat Basin (Precipice Sandstone) include the impacts of impurity or acid gases present in industrial CO2 streams (collaboration with D. Kirste, SFU), inducing carbonate precipitation (in collaboration with S. Golding), and understanding dissolved metal sources and fate. Julie has also worked closely with the CO2CRC, CTSCo, Glencore, SEAL, the NSW government, CI-NSW, and ANLEC R&D, and provided expert opinion to the Queensland Government, and input to Environmental Impacts Assessments.

Julie is currently working with landholders, the QLD regional government, RDMW, councils and industry to understand the sources of methane in aquifers of the Great Artesian Basin, especailly those overlying coal seam gas reservoirs (CSG) (with Arrow Energy, SANTOS, APLNG, H. Hoffman, K, Baublys).

Other projects include gas-water-rock or acid-rock reactivity that modify nano-porosity and gas flow in gas or oil bearing shales.

Julie Pearce graduated with an MCHEM (Hons) degree in Chemistry from the University of York, UK. She then moved to the University of Bristol to complete a Ph.D. in 2007 focusing on laser spectroscopic studies to understand the detailed reaction dynamics of atmospheric processes. From 2007 – 2009 she accepted a Japan Society for the Promotion of Science Postdoctoral Fellowship, hosted at Nagoya University, Japan. There she measured delta 13C and delta 18O isotopic signatures of CO2 simultaneously in real time in the atmosphere using a laser spectroscopic technique to understand anthropogenic and biogenic sources of CO2. After taking a career break to travel in 15 countries in Asia, she moved to Brisbane in 2010 where she is enjoying the surrounding natural beauty of Queensland.

I am an igneous petrologist/volcanologist with a passion for understanding how magmatic systems work. I apply high-resolution petrology, geochemistry and geochronology to diverse geological questions, and my current research focuses on why, how and when volcanic eruptions start. I am particularly interested in minerals hosted in volcanic rocks as they provide a detailed record of magmatic processes through time. My approach combines field observations and detailed microscopy with state-of-the-art analytical techniques and geochemical modelling at the mineral and melt scale. I am fortunate to study a wide range of active and past volcanic systems in different tectonic settings around the world.

I joined UQ in July 2016, after holding a postdoctoral fellowship at Trinity College Dublin for 2.5 years. I undertook my postgraduate research in Spain and The Netherlands (Vrije Universiteit Amsterdam), and received my PhD from the University of Zaragoza in December 2013. I was born and raised by the sea, in San Sebastián.

I am a Senior Lecturer in Geochronology and Tectonics. I am also an Advance Queensland Industry Research Fellow working on using geochronology (and thermochronology) and micro-analysis to improve knowledge in geoscience related to critical minerals. This Fellowship project is a key activity in my research group and I am always looking for motivated students and ECRs to join this research. It is sponsored by Queensland State Government and in collaboration with leading companies in the critical minerals industry.

Broadly speaking, my research advances fundamentals of Plate Tectonics, the unique and unifying theory for our home planet. My group uses a set of field, laboratory, and computational approaches to reveal the geologic history of modern and ancient plate boundaries, focusing on reconstructing the evolution of plate-margin mountains and basins. Such regions are among the most dynamic in the Earth system: their development alters regional and global climate, impacts biogeographic evolution, triggers earthquakes and other geologic hazards, and determines formation and distribution of natural resources such as critical minerals. I have been fortunate to work in some of the most rewarding areas for geologists, including the Himalaya-Tibetan Plateau, Central Andes, eastern Australia, New Zealand, and Pacific Islands. Check out some of my field photos here. I am the lead of UQ Thermochronology Lab. As an in-depth user of UQ RIF (Radiogenic Isotope Facility), I also work with laser ablation ICP-MS with recent work around laser ablation geochronology and geochemistry.

---- New projects in 2024 ----

Recruiting new research students: I am always looking for highly motivated PhD and MPhil students to join my group to work on a range of research topics around geochronology and its applications to critical minerals, global tectonics, and past environmental changes. Please email me for details on projects, funding, and application timelines.
