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 isotope tracing of geological processes. Emphasis is placed on the origin and evolution of igneous rocks as records of Earth's dynamic history. The use of short-lived 'extinct' radiogenic isotope systems for deducing the timing of very early planetary processes, such as formation of Earth's core, 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.
Students are able to (1) demonstrate understanding of how radiogenic isotope systems help constrain timing of important crustal processes; (2) demonstrate understanding of how radiogenic and stable isotopic variations can be used to trace processes of magma generation and the sources of metals in ore deposits; and (3) apply these concepts, particularly integration of radiogenic and stable isotopes, to larger scale lithospheric and mantle processes.
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.

Supplementary assessment is not available in this unit.

  • 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.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available via the Booktopia Textbook Finder, which has the functionality to search by course code, course, ISBN and title, and may also be posted or available at the appropriate school's administrative offices. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
