What you’ll be able to do
Use symmetrical theories (both point groups and space groups) to interpret crystal structures.
Summarize X-ray diffraction theory, operate powder X-ray diffraction experiments, and carry our quantitative analyses (rietveld analysis and structure refinements).
Demonstrate mineral phase transformations, solid solutions / exsolution processes and thermodynamics.
Identify defects and their formation processes in minerals and related host rocks.
Explain the principles governing size-dependent properties of nano-phase minerals in the earth system.
Identify structures, symmetries and superspace groups for quasi-crystals, and aperiodic minerals with incommensurately modulated structures.
