This subject covers geological processes involved in large-scale tectonics and introduces advanced topics in structural and metamorphic geology. The subject will begin with a one-week pre-semester field trip to East Gippsland, where students will develop their geological mapping and structural analysis skills. Lecture topics include the structure and composition of the Earth; plates defined in terms of the thermal and rheological structure of the outer part of the Earth; isostasy; stress and strain in the crust and lithosphere; structural and metamorphic processes in orogenic belts, their origin and their relationship to continental amalgamation and fragmentation; intraplate deformation; deformation mechanisms; shear zone processes; the analysis of poly-deformed terranes and high grade metamorphic processes including partial melting and melt loss.

The field trip will take place in the weeks immediately prior to the normal commencement of classes for Semester 1. The estimated cost of the field trip is $380 and payment options can be found at http://ecommerce.science.unimelb.edu.au/product.asp?pID=73&cID=19&c=241822. Price may vary slightly at time of field trip.

Topics covered include facies analysis and petrology of carbonate, terrigenous and chemical sediments; techniques used in stratigraphic analysis and sequence stratigraphy; sedimentary geochemistry and its applications; principles and applications of palaeontology with respect to stratigraphy; post-depositional processes, including diagenesis and weathering, that alter rocks after their formation; chemical interactions between minerals and groundwater in weathered rocks and weathering products; the processes involved in hydrocarbon generation and organic maturation; and application of sedimentary geology to understanding sediment-hosted ore deposits.

This subject will investigate, both qualitatively and quantitatively, the fundamental physical and chemical processes governing groundwater flow and composition, including aquifer properties, regional geology and hydrology, water-rock interactions, and subsurface microbial activity. Field and laboratory methods used to characterize aquifer properties and groundwater chemistry, including well pumping tests, chemical tracers, and major ion and isotope analyses will also be covered. A two-day field excursion will draw together many of these concepts and topics.

Solving geological problems requires unravelling what happened and when. Petrogenesis is literally 'the origin of rocks' and in this subject several essential tools geologists employ to unravel the complexity of earth processes using chemical information preserved in rocks and minerals will be presented. These include the major, trace element and isotopic compositions of rocks and minerals. Most of this subject relates to igneous processes, however many of the tools can be applied to a broad range of geological problems. These include dating the formation of sedimentary rocks and ore deposits, constraining the ages of metamorphic events, and unravelling palaeoclimate records.

In addition to learning the principles that underpin these techniques, emphasis is placed on how or when they are best applied. It is expected that by the end of the semester you will be able to explain how specific tools work and demonstrate both when it is appropriate, and how to apply them, to resolve petrogenetic problems.

This subject deals with methodologies for extracting geological information out of geophysical datasets. The subject mostly covers potential fields (gravity and magnetic methods) because these datasets are readily available, however it also visits seismic and electrical geophysical methods. GEOL30005 focusses on physics concepts and how they can be used to understand geology. Students work with industry standard software (eg. Geosoft - Oasis Montaj) which performs the maths in the background.

Topics covered include maps, projection systems, datums and GPS; theory, acquisition, processing and interpretation steps involved for gravity and magnetic methods; image enhancement and qualitative interpretation techniques; quantitative style 2.5D geophysical modelling; seismic theory, acquisition, processing and how this integrates with geophysical wire-line well logging; radiometric acquisition/interpretation; and electrical geophysical techniques such as resistivity, induced polarisation, self-potential, electromagnetics and magnetotelurics.

Topics covered include the geological setting and genesis of major metalliferous deposits; magmatic, magmatic hydrothermal, submarine hydrothermal and surficial deposits of major metalliferous and non-metallic resources will be integrated with fluid inclusions, stable isotope, petrographic and field studies.

Depending on staffing and student numbers, excursion sites may include:

• Flinders Ranges of South Australia, where students will be introduced to the style of sedimentation and nature of deformation and exhumation of portions of the Adelaide Geosyncline;
• Broken Hill and regions within the Curnamona Craton of South Australia and New South Wales in which students will be introduced to skills that are relevant to the understanding of packages of deformed and metamorphosed rocks and their interpretation
• Central Australia in which students will be introduced to an intracontinental fold and thrust belt and its relationship to the adjacent metamorphic basement and sedimentary basin;

The Science Research Project is an individual program of supervised research in which the student, in consultation with a supervisor, contributes to the design, execution and presentation of a research project. The project may be ‘stand-alone’ or part of a larger research program being undertaken by the supervisor. The specific details of the project, including its scope and the compilation, analysis and presentation of the results, are negotiated with the supervisor and, as appropriate, the Science Research Project Coordinator(s). Students can undertake a project in most disciplines within the Faculty of Science, and should approach a potential supervisor within a discipline area that is aligned to their research interests. Students will receive feedback on their progress through ongoing consultation with their supervisor.

This subject provides an opportunity for students to gain first-hand experience of scientific research, and is intended for undergraduate students who have achieved excellent results in the discipline related to the project. Undertaking the Science Research Project provides invaluable insights for students considering a career in scientific research.

Geomicrobiology and biogeochemistry involve the study of interactions across interfaces of minerals, water, and microbes, and how such interactions impact environmental conditions and reflect evolution. This subject will survey the fundamental principles of geomicrobiology and biogeochemistry, explain how modern biological processes constrain many geochemical reactions, and show how palaeoenvironmental conditions impacted the evolution and preservation of prokaryotic and eukaryotic organisms across geologic time. This subject will demonstrate how geomicrobiological and biogeochemical knowledge can be applied to problems in academic and government research, and in the petroleum, mineral or environmental industries. We will also look at contemporary “cross-over” applications of geomicrobiology/biogeochemistry to medical microbiology (e.g., coevolution of metals and antibiotic resistance), the microbiology and biogeochemistry of urban/built environments and astrobiological investigation of life’s potential to exist elsewhere in the known universe
