GEOL1014 Geochemistry



To introduce the principles of chemistry as applicable to the Earth.


To provide a sound basis for considering the fundamental chemical processes operating in the Earth system, including bonding and minerals, isotopes and fluid chemistry. The course aims to provide a foundation for further study of mineralogy, petrology, geochemistry and hydrogeology.


The course will provide an introduction to the principles of chemistry required for considering the fundamental geochemical processes operating in the Earth system. Topics will include:

  • Atomic structure and The Periodic Table;
  • Isotopes, isotopic notation, radioactivity and decay mechanisms;
  • Valency and bonding in Earth materials;
  • Elements in the Universe and the Earth;
  • The chemistry and structure of common minerals;
  • An introduction to thermodynamics and mineral stability;
  • Fluids, including silicate melts and aqueous solutions;
  • Chemical reactions in aqueous solutions.
