Earth Sciences
The School of Earth Sciences is a discipline-leader within Australia. With teaching and research functions on both the Townsville and Cairns Campuses of James Cook University, it currently represents the largest academic unit devoted to geology and allied fields within the Australian university system.
Research within the Earth Sciences is the strength of the School and is a designated research focus area for James Cook University. It is supported by a large graduate student enrolment, drawn from all over Australia and including many international students originating mainly from North America and Europe. The School is recognized as a national leader in the field of geoscience, with its research programs widely supported by industry and by the Australian Research Council. Special strengths relate to the fields of Economic Geology, Marine, Sedimentary Geology and Basin Studies, Structural and Metamorphic Geology and Surficial Systems. It is a core node in the Commonwealth- and Industry- funded Cooperative Research Centre in Predictive Mineral Discovery, in partnership with CSIRO, Geoscience Australia, and the Universities of Melbourne, Western Australia and Monash University.

ECONOMIC GEOLOGY
Studies of metalliferous ore deposits including gold, base metals, iron ore, uranium and rare metals, tin and tungsten. Factors in the formation of giant ore deposits. Role of fluids, metamorphism and deformation in the generation of ore deposits. Structural control of ore systems. Evaluation and exploitation of coalseam gas resources.
STRUCTURAL AND METAMORPHIC GEOLOGY
Structural studies at all scales of mountain belts and their development: both ancient and modern orogens are investigated using new microstructural tools that allow past directions of bulk shortening and their changes with time to be correlated with the progressive metamorphic development. Structural and metamorphic studies that investigate processes and mechanisms of deformation and metamorphism in a fully integrated manner using a combined microstructural and chemical approach. Investigations into the structural timing and controls on the origin and development of large-scale ore deposits in particular sites with the specific aim of being able to predict the location of ore bodies with no surface geophysical or geochemical expression in mineralised terrains. Metamorphic reactions during deformational and thermal events and the inter-relationships between them.
MARINE AND SEDIMENTARY GEOLOGY
Sedimentary response of the north Queensland continental shelf to the post-glacial rise in sea-level. Sediment production and distribution and the influence of terrestrial runoff on sedimentation and water chemistry in the Great Barrier Reef province. Sedimentation from the Great Barrier Reef shelf edge into the Queensland trough. Sequence stratigraphy, sedimentology and palaeontology of Neogene strata and the role of sea-level change in determining sedimentary architecture. Deep ocean sedimentary and geochemical evidence of palaeoenvironmental change. Fluvial and coastal processes. Origin and extraction of gas hydrates.
REGIONAL GEOLOGY AND TECTONICS
Evaluation of Proterozoic and Palaeozoic terranes and palaeoenvironmental assessment of the Cretaceous System in northern Australia. Tectonostratigraphic assessment of assemblages in the northern Tasman Orogenic Zone. Stratigraphy and palaeontology of Queensland Palaeozoic sequences. Study of the morphology and petrogenesis of very young flood basalt flows in north Queensland. Characterisation of the processes during granite cyrstallisation, pegmatite emplacement and magmatic fluid evolution.
ENVIRONMENTAL GEOLOGY AND MINESITE REHABILITATION (CAIRNS)
Studies on the hydrology, sedimentology and soil science of mine sites. Hydrology of final pit voids. Environmental radioactivity, geochemistry and biogeochemistry of uranium mines. Smelter emissions at historic base metal mine sites and weathering of slag heaps. Stream sediment and water pollution due to mining and acid sulphate soil formation. Soil pollution as a result of anthropogenic activities and natural processes. Noble metal chemistry of sewage sludge and extraction of metals from biosolids.
