Unit Overview

Description

This unit focuses on the use of key stable and radiogenic isotope systems for unravelling Earth's evolution. The unit examines the basic principles behind nucleosynthesis, radioactive decay and stable isotope fractionation as a basis for exploring the two main applications of isotope geochemistry, namely geochronology and the isotope tracing of geological processes. Emphasis is placed on the petrogenesis of igneous and metamorphic rocks, as recorders of the dynamic history of Earth's mantle and continental crust, with implications for the evolution of the atmosphere and oceans, and on understanding the sources of metals in ore deposits. The use of short-lived 'extinct' radiogenic isotope systems for deducing the timing of very early planetary processes is also outlined. The unit includes an overview of the techniques and instruments used for measuring isotope ratios in geological samples with some practical work.

Outcomes

Students are able to (1) demonstrate understanding of how radiogenic isotope systems help constrain the timing of important crustal processes; (2) demonstrate understanding of how radiogenic and stable isotopic variations can be used to trace processes of magma generation, metamorphism and the formation of ore deposits; and (3) apply these concepts, particularly integration of radiogenic and stable isotopes, to explore larger scale lithospheric and mantle processes.

Assessment

Indicative assessments in this unit are as follows: (1) practical exercises and short reports and (2) theory examination. Further information is available in the unit outline.



Student may be offered supplementary assessment in this unit if they meet the eligibility criteria.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Visit the Essential Textbooks website to see if any textbooks are required for this Unit. The website is updated regularly so content may change. Students are recommended to purchase Essential Textbooks, but a limited number of copies of all Essential Textbooks are held in the Library in print, and as an ebook where possible. Recommended readings for the unit can be accessed in Unit Readings directly through the Learning Management System (LMS).
  • Contact hours provide an indication of the type and extent of in-class activities this unit may contain. The total amount of student work (including contact hours, assessment time, and self-study) will approximate 150 hours per 6 credit points.
