Content

Topics studied in laboratory work include:

  • Phase Diagrams;
  • The factors that determine mineral structures;
  • Introduction to Crystallography;
  • Introduction to Crystal Optics;
  • Mineral and Silicate Classification;
  • Olivine and Garnet Groups;
  • Al2SiO5 Polymorphs;
  • Pyroxene Group;
  • Amphibole Group;
  • Sheet Minerals;
  • Silica Polymorphs;
  • Feldspars;
  • Zeolites;
  • Carbonates;
  • Accessory minerals;
  • Oxides;
  • Sulphur minerals;
  • Other non-silicate minerals.

AIMS

Through laboratory work, the course introduces students to:

  • the chemistry and physical properties of minerals;
  • morphological elements of crystallography;
  • the optical properties of minerals, introduced in conjunction with use of the petrographic microscope;
  • the physical, chemical and optical properties of the major rock-forming mineral groups.

OUTCOMES

Students will become familiar with the following concepts:

  • Phase diagrams;
  • Atomic Structure and bonding in crystalline solids;
  • Principles of structural architecture: including close packing, coordination, number, interstitial sites, coordination polyhedra;
  • Elementary crystallography;
  • Principles of crystal optics;
  • Use of the polarizing microscope.

In addition, they will have a thorough knowledge of the physical, chemical and optical properties of the major rock-forming mineral groups.

Practical and Transferable Outcomes:

  • Interpretation of phase diagrams;
  • Determination of crystal systems from morphological observations;
  • Use of the polarizing microscope to identify major rock-forming minerals;
  • Effective communication of information in writing;
  • Comprehension of scientific concepts, data and papers;
  • Independent study;
  • IT skills.
