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.

This work is applied to rocks to decipher zoning and modification of metamorphosed hydrothermal alteration zones associated with ore deposits, metal mobility during metamorphism, partial melting of high-grade metamorphic rocks, and orogenic processes.

  • Francisca Maepa
    Francisca Maepa
    PhD candidate in Mineral Deposits and Precambrian Geology

    The purpose of my project is to find regions that are favorable for mineral deposits by employing data integration, machine learning techniques and, geo-statistics. This project will test these methods initially on the Swayze Greenstone Belt (SGB) and then attempt to apply the methods more generally to the Abitibi subprovince. The SGB is an extension of the mineral prolific Abitibi Greenstone Belt (AGB), and although there is known gold mineralization in the Swayze, it is not as mineral endowed as other parts of the AGB. The project also seeks to understand the effect of incorporating high-resolution geophysical datasets, and how geophysics affects predictive mineral mapping results. The study will help to determine the optimum data to use in both greenfield and brownfield exploration, as understanding which datasets to collect at the early stages of exploration is essential.
