This course is designed to develop an advanced understanding of deformation processes and structures produced by displacement and deformation in the Earth's lithosphere at scales ranging from the tectonic plate scale, down to the crystal lattice scale. Emphasis is placed on understanding (1) the geometry and types of structures produced by complex crustal deformation histories involving contractional, extensional and wrench regimes, (2) the deformation processes which control the microstructural evolution of deformed rocks, (3) factors influencing the strength and mechanical behaviour of the Earth's crust and underlying mantle lithosphere, (4) deformational controls on crustal-scale fluid flow and applications to understanding ore genesis and earthquake processes, and (5) the large-scale geodynamic processes controlling plate motions and crustal deformation.
Upon successful completion, students will have the knowledge and skills to:
- Recognise, map and interpret the geological structure of deformed continental regimes, from mildly deformed upper crustal regimes to complexly deformed, deeper crustal regimes.
- Interpret the relative timing of formation of structures, the kinematics of deformation, and progressive deformation histories.
- Predict the geometry and location of structures at depth or in areas of poor outcrop.
- Apply an understanding of structural geology in the mining and resource exploration environment.
This course develops research skills of the individual student through their involvement in their own research project. The student will investigate aspects of structural geology and tectonics in respect to topical content in global tectonics or structural geology with particular focus on connecting to Australian examples. Guest researchers will be asked to give talks in each module that connect the lectures to ongoing research in the school
We expect to run the mapping exercise as a short (day-length) field outing close to ANU. This will be replaced by an online exercise if the class is unable to proceed in person.
Additional Course Costs
There will be no additional class costs.
Examination Material or equipment
Students will take the examination online using a Wattle quiz, so they will need access to a computer during the times in question.
We will have a number of on-line exercises for you to complete so we expect you to have access to a laptop or tablet (with keyboard) for labs and homework.
Recommended student system requirements
ANU courses commonly use a number of online resources and activities including:
- video material, similar to YouTube, for lectures and other instruction
- two-way video conferencing for interactive learning
- email and other messaging tools for communication
- interactive web apps for formative and collaborative activities
- print and photo/scan for handwritten work
- home-based assessment.
To fully participate in ANU learning, students need:
- A computer or laptop. Mobile devices may work well but in some situations a computer/laptop may be more appropriate.
- Speakers and a microphone (e.g. headset)
- Reliable, stable internet connection. Broadband recommended. If using a mobile network or wi-fi then check performance is adequate.
- Suitable location with minimal interruptions and adequate privacy for classes and assessments.
- Printing, and photo/scanning equipment
For more information please see https://www.anu.edu.au/students/systems/recommended-student-system-requirements
- Students will be given verbal feedback to the whole class, to groups, and to individuals. This will address their general performance in the course.
- In exceptional cases a student might receive written feedback, for example in respect to the need to ensure practical reports reflect individual effort.
- Collaborative activity in small identified groups will be encouraged. However students must ensure that they submit their own work, not the work of others.
- There will be an assessment exercise approximately every three weeks during the course.
- The marks for the assessment exercises will provide feedback on progress and prowess.
Student FeedbackANU is committed to the demonstration of educational excellence and regularly seeks feedback from students. Students are encouraged to offer feedback directly to their Course Convener or through their College and Course representatives (if applicable). The feedback given in these surveys is anonymous and provides the Colleges, University Education Committee and Academic Board with opportunities to recognise excellent teaching, and opportunities for improvement. The Surveys and Evaluation website provides more information on student surveys at ANU and reports on the feedback provided on ANU courses.
|Summary of Activities
|General InformationThe course will involve three hours per week in lectures, with one two hour practical. The lecture material is broken into five sections that cover different aspects of tectonics, deformation and structure. Examples are taken from / related to the geological history of the Australian plate where possible so that you will also develop an appreciation of the geological events that shape the Australian continent and the Australian plate.Labs broadly follow the lectures but, for logistical reasons, run as a parallel activities that can span multiple weeks. In each module, we will have one expert talk that builds upon the material in lectures.
|There will be 5 short quizzes during the semester that will help you to calibrate your knowledge from the course material for each module and which you can use for revision. The first of these quizzes will be a refresher on plate kinematics which you will be allowed to re-take after an optional tutorial. (20% on these quizzes)Lab-based assessments will be worth 20% of the course in total. One assessment will be an exercise on interpreting sandbox models that you will be running in the lab. The second will be a mapping exercise.There will be a presentation and report that together make up 20% of the course assessment. The final exam will be worth 40% of the course.
|Module I. Introduction to Global TectonicsThis module introduces the concepts of global-scale tectonics, plate motions, the nature of plate boundaries and the geological structures characteristic of large-scale deformation of the crust. We address the history of plate tectonics and what we know about the physical evolution of the continental crust through time. In this module, we will lead you on a journey through typical structural features of the Earth's crust with examples from the Australian plate.
|Module II. Structures in the EarthThis module aims to develop student intuition and proficiency in 3- and 4-dimensional visualization and thinking and teach the fundamentals of rock deformation using natural examples.You will be given an overview of the geometry and type of structures produced by complex crustal deformation histories involving contractional, extensional and wrench regimes over a wide range of spatial and temporal scales. You will learn how to recognise structural features using satellite imagery or geological maps and will learn how to construct geological profiles.
|Module III. Theoretical underpinnings: stress, strain and geometryThe theory of stress and strain, an introduction to continuum mechanics as relevant to structural geology and tectonics. In order to understand geological structures in more detail, we need some background understanding of how stresses and strains work, how they are measured, and how you can use these concepts to interpret what you see in the field.
|Module IV. Brittle DeformationWhen rocks undergo rapid, localised deformation, refer to the process as "brittle deformation". Typically brittle features in the Earth's crust are faults and we can understand much about the stress and deformation if we understand faults, their rupture and associated seismic energy release.
|Module V. Ductile Deformation: Folding, shearing and associated structuresDuctile deformation occurs when rocks are able to accommodate large deformations without fracturing. You will learn how to recognise elements of ductile deformation such as folding, shearing and stretching.We will take you though the fundamentals of modern fold theory. We will see how folds represent important windows into local and regional deformation histories. You will learn how to describe geometry and different styles of folding and will understand how we can use them to derive important information about the type of deformation. You will then learn about structures associated with folding and see how they can be used to map and understand the deformation history.

PoliciesANU has educational policies, procedures and guidelines, which are designed to ensure that staff and students are aware of the University’s academic standards, and implement them. Students are expected to have read the Academic Misconduct Rule before the commencement of their course. Other key policies and guidelines include:
Assessment RequirementsThe ANU is using Turnitin to enhance student citation and referencing techniques, and to assess assignment submissions as a component of the University's approach to managing Academic Integrity. For additional information regarding Turnitin please visit the ANU Online website Students may choose not to submit assessment items through Turnitin. In this instance you will be required to submit, alongside the assessment item itself, hard copies of all references included in the assessment item.
Moderation of AssessmentMarks that are allocated during Semester are to be considered provisional until formalised by the College examiners meeting at the end of each Semester. If appropriate, some moderation of marks might be applied prior to final results being released.
Students are expected to attend lectures and practicals to benefit from discussion of required readings from the course textbook.
Please note, that where a date range is used in the Assessment Summary in relation to exams, the due date and return date indicate the approximate timeframe in which the exam will be held and results returned to the student (official end of Semester results released on ISIS).
