Ore Deposits and Mineral Exploration

 

Research on a wide variety of ore deposit types and mineral exploration methodology forms a core component of many of the research programs in the Harquail School of Earth Sciences. Our faculty and student researchers are conducting research globally on problems of relevance to the mineral exploration industry.

Ore deposit geology is the study of how mineral deposits form, which provide the necessary raw materials, such as Fe, Ni, Cu, Zn and the rare metals (Ta, Nb, REEs), for the past and continued development of our modern societies. Mineral deposits have formed in a variety of settings throughout Earth history which reflect in part the different conditions under which the ore minerals form. Thus, ore deposits are therefore grouped into deposit types which reflect their setting and host rocks. Simple examples include magmatic Fe-Ti-Ni-Cr-PGE deposits hosted by mafic rocks, Fe oxide ores which formed as chemical precipitate in sedimentary environments, deposits associated with volcanic centres of either submarine (i.e., massive sulphide ores of Cu-Zn-Pb-Au-Ag) or subaerial (i.e., epithermal ores rich in Au-Ag), settings, and vein and replacement ore deposits either related to intrusive centres (e.g., porphyry and skarn deposits) or independent of such an association (e.g., carbonate replacement deposits or MVT deposits and orogenic Au deposits). By studying the geological setting and conditions by which deposits formed, a better understanding of relevant processes are appreciated. The latter information is used to define ore- deposit models, which is the basis of mineral deposit exploration.

The time-space distribution of ore deposits and relationship to large-scale geological processes (e.g., plate tectonics), Earth’s secular evolution, and development of the atmosphere and hydrosphere are all relevant to ore deposit geology. Collectively these aspects of ore deposits are studied under metallogeny. An excellent example of this is the apparent abundance of large porphyry-type Cu±-Au deposits spatially associated with magmatic arc settings in the late Phanerozoic rock record versus older rocks – what is the reason for this and how is it relevant to exploration.

All of the ore deposit types mentioned above and more are the topics of much of the core research in the Harquail School of Earth Sciences by the faculty and student researchers that include undergraduates, graduates and post-doctoral scientists.
