Overview This course offers a general overview on the most common experimental methods used in petrology to study physical and thermodynamic properties and phase equilibria of solid, liquid and gaseous phases at magmatic and metamorphic conditions. Several pressure/temperature devices are presented and discussed together with the basic principles for making starting materials and the evaluation of run products. Objective The course will provide the fundaments of experimental petrology. The main goals are the acquisition of basic knowledge about experimental facilities and the design and setup of an experimental study targeted to obtain quantitative data on phase relations, thermodynamic, kinetic and rheological properties of geological samples as well as the examination, analysis and evaluation of run products. At the end of the course, students should be able to design appropriate experimental plans and to evaluate experimental data independently.

Poslední úprava: doc. Alessandro Fabbrizio, Ph.D. (04.04.2022)
The examination consists in an oral discussion about an experimental plan elaborated by the student, of the related subjects covered during the course, and in the interpretation and evaluation of experimental data and run products. Instructions for the developmnet of the experimental plan. The themes are assigned to the students during the first lecture. Your experimental plan will be discussed at the exam. The experimental plan should include and discuss the following points: a) choice of the system (natural or synthetic) and of its chemistry; b) procedure for the preparation of the starting material; c) choice of the more appropriate sample container; d) determine the chemical and physical parameters at which the experiments will be performed (e.g. pressure, temperature, oxygen fugacity, water content, time, cooling rate, etc.); e) determine the number of runs you need to reach the target(s) of your study; f) choice of the experimental facility(ies) suitable for the investigation; g) expected results (e.g. texture and chemistry of the synthetic run products, proof(s) for equilibrium); h) discuss the potential problems and pitfalls you could encounter during the investigation; i) preparation of the experimental samples for analytical investigation; l) choice of the analytical tool(s) for studying the run products; m) application of the experimental results to a real geologic situation/environment (e.g. pressure/temperature conditions of magma storage; cooling rate of a lava flow; comparison with natural rock textures; chemical/textural evolution of crystals in a magma body). |
