Study of magmatic systems including the nature and origin of igneous materials and links with the physical processes of volcanology.
This course is designed to examine the nature, origin, and interpretation of igneous rocks and mineral assemblages, as well as the magmatic processes that have produced these materials. Additionally, it aims to develop an understanding of the petrological evolution of the crustal lithosphere within a modern plate dynamic framework. Students taking this course will receive a broad grounding in the experimental, petrographical and geochemical aspects of igneous petrogenesis and magmatic processes. Emphasis will also be given to the petrological aspects of volcanology, which will benefit those students wishing to do volcanological research. This course consists of two lectures and one laboratory class in each week of the second semester.
Learning OutcomesStudents successfully completing this course will:Realize the importance of igneous rocks in geology and to society.Identify and classify igneous rocks and their geological environments.Use geochemistry to explain why magma is generated, diversifies and erupts.Use geochemical data, thin sections, and maps to reconstruct the magmatic and volcanological histories.Discuss physical volcanological processes with relevance to magma properties.
This course will provide students with an opportunity to develop the Graduate Attributes specified below:
Critically competent in a core academic discipline of their award
Students know and can critically evaluate and, where applicable, apply this knowledge to topics/issues within their majoring subject.

Relationship of GEOL336 to other coursesYou cannot take GEOL336 without first completing GEOL242. GEOL336 is a prerequisite for GEOL474 (Igneous Petrology and Geochemistry), and students wishing to take GEOL476 (Volcanology) are strongly recommended to take this course.AssessmentLaboratory weeks 1-10 (5%) Class weeks 1-10 (5%) participation - 10%Final Laboratory Examination from both terms (Week 11) - 30%Virtual Fieldtrip week 11 and 12 participation (10%) and reflection (10%) - 20%Final Examination from both terms (Closed Book; 3 hours; UC Exam Period) - 40%Lab classes will comprise a mix of microscope work, geochemical data analysis and computer-assisted learning:• Introductory labs on igneous petrographic nomenclature and thin section descriptions• Introduction to the use of geochemical data on igneous rocks to describe and identify magmatic processes• Edible and explosive igneous experiments.Participation in lab will be assessed by the full completion of the lab.Participation in lecture will be assessed by the completion and handing in of in class assignments.

Topics to be covered include:• Mineralogical and chemical classification of igneous rocks; igneous associations and relationships with global tectonic settings.• Basalt crystallization and the origin of basalt magmas.• Classification and nomenclature of granites; origin, emplacement and tectonic significance of granitoids using especially NZ examples.• Petrological structure of intra-oceanic and continental arcs and petrogenesis of subduction-related magmas.• Mafic-felsic magma interactions in high level magma chambers. • Volcanic processes with emphasis on lava, ballistics, pyroclastic flows, lahars and debris avalanches.• Geochemical, volatile, and crystallisation influences on eruption style and experimental volcanology.• Controls on magma viscosity.• Iceland case study.Participation in lecture will be assessed by the completion and handing in of in class assignments.Schedule of Laboratory ClassesLaboratory classes will be assigned by timetabling and will take place in the 300 level lab, Room 220, Geological Sciences Department. Each student will be allocated a polarising microscope.
GENERAL INFORMATIONMarks and GradesThe 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 C84 – 80 A- 65 – 69 B- 50 – 54 C- Below 50 D/EThe Department of Geological Sciences reserves the right to adjust this mark/grade conversion, when deemed necessary.Late WorkIt 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 LiaisonAlex Nichols (room 321, HUalex.firstname.lastname@example.orgUH, phone (03) 364 2987 ext 94410) 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 DisabilitiesStudents with disabilities should speak with someone at Disability Resource Service. Their office is on Level 2 of the Puaka-James Hight Building (Central Library). Phone: +64 3 369 3334 or ext 93334, email: email@example.comPolicy on Dishonest PracticePlagiarism, 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 GradesStudents 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. Special Considerations ApplicationsIf 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 a Special Considerations application form, available from the Registry or the Student Health and Counselling Service. This should be within five 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 Special Consideration applications, please refer to the Enrolment Handbook or visit http://www.canterbury.ac.nz/exams/special-consideration.shtml. You have the right to appeal any decision made, including Special Considerations decisions. Missing of TestsIn rare cases a student will not be able to sit a test. In such cases, the student should consult with the course co-ordinator to 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.
