Description

This course will concentrate on the geochemical aspects of igneous petrology. At every stage we will be seeking to discover what magma chemistry can tell us about the nature of igneous processes and the relationships between igneous rocks. Following coverage of "core material" we will discuss particular igneous processes, the petrogenesis of certain rock suites and select some of the "hot topics" in igneous petrology.

This course will concentrate on the geochemical aspects of igneous petrology. We will examine how geochemical data are collected, evaluated, interpreted and presented, and using real geochemical datasets we will discover what magma chemistry can tell us about the nature of igneous processes and the relationships between igneous rocks.

In weekly seminars we will discuss some of the ‘hot topics’ in igneous petrology, outline techniques used to measure geochemical data and how to tackle the marked assignments. Students will also be shown the sample preparation and analytical facilities available in the Department, for possible use in their Honours’ and Master’s theses. Marked assignments will include problem sets where the students have to manipulate, describe and interpret geochemical datasets in terms of igneous processes, a poster presentation on a subject preferably related to their chosen Honours’ or Master’s thesis topic, and finally an illustrated report in the style of a journal article presenting, describing and interpreting an existing geochemical dataset, applying what they have learnt throughout the course.

An understanding of chemistry, mathematics, mineralogy and some experience of using Excel or an alternative spreadsheet and graphing program is recommended.
Learning Outcomes
1) Realise the importance of geochemistry and igneous petrology to all aspects of geology.
2) Choose the appropriate geochemical techniques to test geological hypotheses.
3) Manipulate and interpret geochemical data to understand igneous processes.
4) Discuss the benefits and limitations of geological interpretations based on geochemical data.

Marks and Grades
The Department of Geological Sciences uses the following scale to convert marks into grades:
100 – 90 A+ 75 – 79 B+ 60 – 64 C+
89 – 85 A 70 – 74 B 55 – 59 C
84 – 80 A- 65 – 69 B- 50 – 54 C-
Below 50 D/E
The Department of Geological Sciences reserves the right to adjust this mark/grade conversion, when deemed necessary.

Late Work
Late work should be accompanied with a short note explaining 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-ends and holidays.

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 Geological Sciences to arrange alternative procedures. This must be done well in advance of the set date for the test, unless the situation is covered by the aegrotat regulations.

Reconsideration of Grades
• Grades for individual items of coursework may be reassessed, and in the first instance students should speak with the course coordinator. If an agreeable solution cannot be reached students should then speak to the Head of the Geological Sciences Department. Reconsideration should normally be requested within 4 weeks of the test or the return of the item of assessment.
• Grade reconsideration for courses as a whole can be obtained by applying to the Registry within 4 weeks of the date of publication of the final results. Students should refer to UC Calendar under general course and examination regulations for details of the appeal process.

Academic Liaison
Tom Brookman and Tim Stahl currently share the Chairperson role on the Postgraduate Liaison Committee. A student representative is appointed to the Liaison Committee at the start of the semester. Please feel free to talk to Tom, Tim or the student representative about any problems or concerns that you might have.

Students with Disabilities
Students with disabilities should speak with someone at the Disability Resource Service. Inquire in the first instance at Level 3 Rutherford Building  Email: disability@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 named 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.
