Description

Nature and origin of structures produced by deformation in the Earth’s crust, and material properties of rocks that affect the way in which they respond. Practical geometric methods associated with deriving and representing the three dimensional form of structures commonly encountered in geological practice, and synthesis of tectonic settings. This course also covers large-scale geometry and processes of plate tectonics, and topics in global geophysics linked to current observation and plate tectonic theory.

When rocks in the Earth’s crust are subjected to stresses generated by dynamic tectonic processes, they are deformed into a variety of structures. The material properties of rocks affect the way in which they respond and this course introduces the physical principles, which explain the origin of common structures, such as folds and faults.

While the lecture course emphasizes the nature and origin of the range of deformation structures, the laboratory course concentrates on the practical geometric methods associated with deriving and representing the three dimensional form of such structures. This involves the use of various projection techniques to solve problems that are commonly encountered in geological practice. In the latter part of the course, a synthesis of the way in which characteristic associations of structures develop into distinctive styles in different tectonic settings are introduced.

The course ends with an introduction of the large-scale geometry and processes of plate tectonics. Selected topics in global geophysics (seismology, paleomagnetism, geomagnetism, heat flow and isostasy) provide an overview of the nature of global processes, linked to current observation and plate tectonic theory.

Learning Outcomes

  • Goal of the Course
    Provide students with principal deformation processes occurring in the lithosphere and their underlying causes.

    Learning Outcomes
    Students successfully completing this course will:
  • have an understanding of the basic principles of the mechanics and kinematics of rock deformation;
  • be familiar with a range of common deformational structures, their classification, terminology and the way in which they are associated in the principal tectonic regimes generated by primary plate interactions and gravitational processes; and
  • be able to apply a range of standard techniques to the analysis of geologic structures.
  • have developed a fuller understanding of the nature of plate tectonics, the structure of the Earth’s crust and interior;
  • develop an understanding of the basic principles of global geophysics in the fields of seismicity, magnetism, isostasy and heat flow, and their relationship to plate tectonics and the structure of the Earth’s interior.

    Summary of the Course Content
    The topics coved by this course are:
  • Structural Geology (kinematic analysis, brittle and ductile deformation, stress and strain, description of major deformation structures)
  • Global Geophysics (forces that drive plate motion and thus cause major deformation structures in the lithosphere).

Additional Course Outline Information

Academic integrity

Marks and Grades
The Department of Geological Sciences uses the following scale to convert marks into grades:
100 – 90 A+ 74 – 70 B 54 – 50 C-
89 – 85 A 69 – 65 B- 49 – 40 D
84 – 80 A- 64 – 60 C+ Below 40 E
79 – 75 B+ 59 – 55 C

The Department of Geological Sciences reserves the right to adjust this mark/grade conversion, when deemed necessary.

Late Work
It is the policy for this course that late work is not accepted. Or, late work should be accompanied with a detailed explanation of why the work is late. The work will be marked and marks will be subtracted for each day the work is late. Days late include week-end and holidays.

Academic Liaison
Christopher Oze (room 329, HUchristopher.oze@canterbury.ac.nzUH, is in charge of liaison with students in geology courses. Each year level will appoint a student representative(s) to the liaison committee at the start of the semester. Please feel free to talk to the Academic Liaison or the student rep about any problems or concerns that you might have.

Students with Disabilities
Students with disabilities should speak with someone at Disability Resource Service. Their office is room 317 in the Rutherford Building. Phone: 364 2350 (or ext. 6350), email: disabilities@canterbury.ac.nz

Policy on Dishonest Practice
Plagiarism, collusion, copying and ghost writing are unacceptable and dishonest practices.
• Plagiarism is the presentation of any material (text, data, figures or drawings, on any medium including computer files) from any other source without clear and adequate acknowledgement of the source.
• Collusion is the presentation of work performed in conjunction with another person or persons, but submitted as if it has been completed only by the names author(s).
• Copying is the use of material (in any medium, including computer files) produced by another person(s) with or without their knowledge and approval.
• Ghost writing is the use of another person(s) (with or without payment) to prepare all or part of an item submitted for assessment.

In cases where dishonest practice is involved in tests or other work submitted for credit, the student will be referred to the University Proctor. The instructor may choose to not mark the work.

Reconsideration of Grades
Students should, in the first instance, speak to the course co-ordinator about their marks. If they cannot reach an agreeable solution, students should then speak to the Head of the Geological Sciences Department. Students can appeal any decision made on their final grade. You can apply at the Registry to appeal the final grade within 4 weeks of the end of the semester. Be aware that there are time limits for each step of the appeals process.

Aegrotat Applications
If you feel that illness, injury, bereavement or other critical circumstances has prevented you from completing an item of assessment or affected your performance, you should complete an aegrotat application form, available from the Registry or the Student Health and Counselling Service. This should be within seven days of the due date for the required work or the date of the examination. In the case of illness or injury, medical consultation should normally have taken place shortly before or within 24 hours after the due date for the required work, or the date of the test or examination. For further details on aegrotat applications, please refer to the Enrolment Handbook. You have the right to appeal any decision made, including aegrotat decisions.

Missing of Tests
In rare cases a student will not be able to sit a test. In such cases, the student should consult with the course co-ordinator or the Head of the Department of Geological Sciences to arrange alternative procedures. This must be done well in advance of the set date for the test.
