Job description

Natural resources are needed to construct infrastructure to increase mobility, to develop digital life, and to produce renewable energy. The current rate of discovery of mineral deposits is lower than the demand of society. In part, because most mineral deposits close to the surface have already been found and recycling techniques do not yet produce enough quantities to supply this demand. Therefore, mineral exploration has been focusing on deep subsurface regions, which requires the application of geophysical methods. Thus, the successful application of geophysical methods depends on understanding the geophysical anomalies of the different rocks and these anomalies are associated with the petrophysical characteristics. For this reason, this fully funded four-year PhD project will explore the geological source of the electromagnetic anomaly of the Lisheen Zn-Pb deposit in Ireland aiming to construct better subsurface models for solving geological challenges in mineral exploration. While the distribution of minerals suggests that the feeder zones should be conductive because they have higher concentrations of Cu and Ni sulphides, the EM data from Lisheen deposit is used as a textbook example for a conductivity anomaly associated with the Zn-Pb mineralization, which is not composed of high conductive sulphides. One possibility is that the EM response is associated with the pyrite cap around the Zn-Pb ore. However, the pyrite in this cap is described as mainly disseminated and in veins, which contradicts the main premises of the application of EM data, the requirement for massive (to semi-massive) conductive sulphides. Given this puzzle and lack of clear understanding of the origin of the association between mineralogy and geophysical data, this project proposes to conduct a detailed petrophysical characterization of the different units in Lisheen. This data will be further utilized to guide the 3D modelling of EM data to understand the association with the mineralization and define exploration vectors for exploration of this type of deposit. The expected outputs are a database of petrophysical data for Lisheen, simulated multiphysics data using the 3D geological model (based on extensive drilling), 3D EM inversion, and geophysical exploration vectors. The physical properties (velocity, magnetic susceptibility, electrical conductivity, density, and chargeability) of the rock samples will be acquired in the new Petrophysics Laboratory at UCD. The skills that will be acquired in this project are highly valued across most industries. This project is suitable for a candidate who wishes to conduct applied research that makes an immediate impact in the real world.
