Ore Deposit Geochemistry, Hydrology and Geochronology KEA709

Note:

Offered every second year

Introduction

This unit gives students an up-to date review of the theory and practice of geochemistry, hydrology and geochronology as applied in mineral exploration, environmental management and studies of ore deposit genesis. The unit provides a comprehensive introduction to the chemistry of surface waters and hydrothermal systems including metal solubility, mineral stability, and the use of stable and radiogenic isotopes as tracers of hydrothermal processes. Physical controls on hydrothermal fluid -flow and controls on fluid chemistry, which influence the types and locations of ore deposits are addressed, as are the geochemistry, metallogenesis and ore-forming potential of magmatic arcs. Various methods of dating mineralising events are explained. Advanced techniques for ore deposit footprint, vectoring and fertility studies are also introduced. The major assessment task for this unit requires students to provide a pyrite bearing sample for analysis. Prior to the short course, a polished laser ablation mount is prepared for each sample, reflected light optical microscopy images acquired and a pyrite grain (or grain aggregate) selected for laser ablation ICPMS analysis. During the short course, the resultant LA-ICPMS trace element/lead isotopic maps of the pyrite are interpreted in terms of ore deposit type, location within the alteration halo, conditions of pyrite deposition and hydrothermal fluid chemistry. Ore Deposit Geochemistry, Hydrology and Geochronology is available as both an OPTIONAL unit in the Mastery block of the Master of Economic Geology degree or as one of three CORE OPTION capstone coursework units (two selected) that may be taken during the Research/Project block of the degree. This unit involves 155 hours of assessment, including 70 hours outside of the intensive teaching period/s. The total volume of student learning for the unit is ~230 hours.

Note

Please check that your computer meets the minimum System Requirements if you are attending via Distance/Off-Campus.

Units are offered in attending mode unless otherwise indicated (that is attendance is required at the campus identified). A unit identified as offered by distance, that is there is no requirement for attendance, is identified with a nominal enrolment campus. A unit offered to both attending students and by distance from the same campus is identified as having both modes of study.

Learning Outcomes

  • Combine geochemical and petrological data to interpret hydrothermal ore deposits formed in different tectonic settings
  • Explain physical controls on fluid flow in hydrothermal systems and their implications for mineral exploration strategies.
  • Relate chemical controls on metal solubility (transport and deposition) in crustal fluids to mineral exploration strategies.
  • Select samples and laboratory methods to evaluate the tectonic setting, age and/or chemical footprint of hydrothermal ore deposits
  • Communicate geochemical and hydrological concepts, or research findings, to an audience of industry or academic peers
