Hosted by: University of Tasmania

Dates: 30th of May - 03th June 2022

Venue: Codes Conference Room, Geo353; Geology/Geography Building, Sandy Bay Campus; Course starts at 9 am 

The course is intended for Honours students and other Post-Graduate students with an interest in the formation and evolution of basic and ultrabasic magmas . For those interested in magmatic ore deposits, it is recommended that this course is taken in conjunction with the "Igneous Geodynamics and Magmatic Ore Deposits” course taught at the University of Melbourne.

The first two days cover key theoretical aspects of petrology including units of concentration, solid solutions and mineral formulas, activities and equilibrium, the phase rule, mass balance, phase diagrams, equilibrium/fractional crystallisation.

The third day includes an example of a large layered intrusion (Dovyren Magmatic Complex, Siberia), followed by: the effects of pressure and H2O on melting and crystallisation; causes of melting and crystallisation; and an introduction to the concept of distribution coefficients for trace elements.

Day four covers trace elements in main rock-forming minerals, modelling of crystallisation process, several aspects of petrogenesis and mineral chemistry of MORBs and subduction-related lavas. 

Day five will introduce studies of melt inclusions and present examples from subduction-related lavas and komatiites.

Each day will consist of 3 lectures (~1 hour each), each followed by 1-hour practicals on the subject of the preceeding lecture. Each practical will be assessed, and an average of three daily practicals will be given as a mark for each day. The mark for the course is the average of the five daily marks.

The course is held in Hobart at the University of Tasmania. Directions on how to find the venue will be provided to the enrolled students.
