GEOLOGY 3013 - Tectonics III

North Terrace Campus - Semester 1 - 2016

This course will develop knowledge of the Earth as a four-dimensional dynamic system. The megascopic structure of the earth -oceanic and continental crust and lithosphere, and the asthenosphere, will be introduced and compared. The basic dynamic potentials acting on the Earth (heat, gravity) will be examined, and their diverse first order effects explored (isostasy, convection, exhumation, pluming). The concepts of rifting and ocean formation will be examined, as will those of subduction and mantle plumes. Processes of orogenesis will be examined in depth. Recent and Mesozoic evidence (structural, geochemical, geophysical, sedimentological) for the operation of these processes will be examined. We will examine evidence and constraints on interpretation of these processes operating in past geological eras: the Palaeozoic, Proterozoic and Archaean. Emphasis will be placed upon understanding examples from the tectonic evolution of the Australian Plate. Details of field trip communicated at start of the course.

  • Learning Resources
    Required Resources
    The following items are required resources for all practical exercises: paper, ruler, protractor, pencils (including colour pencils) and calculator. Some practicals will require the use of a (laptop) computer, basic software such as MS Excel and/or software (freeware) that will be given to you during or before the practicals. Bringing a laptop to the classroom for these practicals is strongly recommended, however the exercises can be completed at home as well and/or in team. Required reading will be issued from journal articles that will be available through the Library and/or MyUni. There is no recommended textbook for this course, although course materials are generally sourced from the textbooks listed below (pdf chapters will be made available if required). Course notes (recordings) and digital copies of all slideshows used in lectures and practicals will be readily available on MyUni.

    This course will include a field component. The following Field Kit is compulsory for this component and items can be purchased at Unibooks:
    - good quality (hardback) notebook
    - compass/clinometer
    - hand lens

  • Learning & Teaching Activities
    Learning & Teaching Modes
    The course consists of two one-hour lecture sessions per week for 12 weeks plus accompanying practical work, most weeks. See section below for details on practical scheduling.

    2 x 1-hour lectures/week - see timetable
    1 x 3-hour practical work per week for most of the semester. The practicals are hands-on practice for the theory material covered in the lectures. Note that some practicals require further work at home. Some of the practical time will be used for student presentations (group work).
    The course will include field work during the mid-semester break

    Workload

    The information below is provided as a guide to assist students in engaging appropriately with the course requirements.

    A student enrolled in a 3 unit course, such as this, should expect to spend, on average 12 hours per week on the studies required. This includes both the formal contact time required to the course (e.g., lectures and practicals), as well as non-contact time (e.g., reading and revision).

  • Assessment

    The University's policy on Assessment for Coursework Programs is based on the following four principles:

    1. Assessment must encourage and reinforce learning.
    2. Assessment must enable robust and fair judgements about student performance.
    3. Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
    4. Assessment must maintain academic standards.

    Assessment Related Requirements
    Attendance at practicals and field exercises is compulsory and will be recorded. The learning outcomes for this course are substantially dependent on this hands-on experience and practice. Therefore, missing any practical class or field session in a semester without an allowed absence will result in a grade of FAIL being recorded for the course. Students are able to apply for an allowed absence from a class by submitting the application form, with appropriate supporting documentation, to the Course Co-ordinator.
    Assessment Detail
    Practical exercises (30%): Six in-class practical exercises require a short report including results obtained during the exercises. More details will be given at the start of each Practical session.

    Seminar (10%): A small group exercise (~4 students per group). Students are asked to research a topic (each group has a different topic, topics available in week 2) and present this as a short group seminar (15 minutes). Presentations will be held in weeks 11 and 12.

    Field Trip exercises (10%): This assignment includes the following tasks: (1) Field Note Book and (2) Field data collection and analysis (structural readings, small mapping and logging exercises)

    Final exam (50%): A final written exam will be used to summatively assess the course materials.
    Submission
    Late Submission
    If an extension is not applied for, or not granted then a penalty for late submission will apply. A penalty of 10% of the value of the assignment for each calendar day that the assignment is late (i.e. weekends count as 2 days), up to a maximum of 50% of the available marks will be applied. This means that an assignment that is 5 days late or more without an approved extension can only receive a maximum of 50% of the marks available for that assignment.
    Course Grading

    Grades for your performance in this course will be awarded in accordance with the following scheme:

    M10 (Coursework Mark Scheme)
    Grade Mark Description
    FNS   Fail No Submission
    F 1-49 Fail
    P 50-64 Pass
    C 65-74 Credit
    D 75-84 Distinction
    HD 85-100 High Distinction
    CN   Continuing
    NFE   No Formal Examination
    RP   Result Pending

    Further details of the grades/results can be obtained from Examinations.

    Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.

    Final results for this course will be made available through Access Adelaide.

  • Student Feedback

    The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.

    SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

  • Student Support
  • Policies & Guidelines
  • Fraud Awareness

    Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.

The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
