((GEOL 112 or GEOX 112) and (EAOS 111 or EAOX 111)) or (18 GEOL points and (GEOG 101 or 18 CHEM points))
GEOL 362
Schedule C
Teaching Arrangements
Two lectures and one 3-hour laboratory per week.
Paper Structure
The course is divided into four modules, covering the theory and both high and low temperature applications of:
  • water-mineral reactions
  • trace element distributions
  • stable isotopes
  • radioactive and radiogenic isotopes
A unifying theme of the course is the topic of global biogeochemical cycles. Implications for economic mineralisation will also be considered.

Assessment is approximately an even split between internal (ongoing during the semester) and external (final exam).
Assessments for GEOL 362 are set and graded differently to GEOL 262 to reflect greater background knowledge and higher expectations of students taking the paper at 300-level.
Background requirements: Basic knowledge of elementary mathematics and chemistryGEOL 262 is for students in their second year of a geology or equivalent degree. GEOL 362 is for students in their third year of a geology or equivalent degree.
