Biography
Robert Doyle is a PhD researcher in the iCRAG raw materials research spoke. Robert graduated with a BSc in Geology in 2015 from University College Dublin. He worked as a Junior Exploration Geologist for Vedanta Exploration Ireland Limited for 6 months before joining iCRAG as a Research Assistant in January 2016. In January 2017, Robert began his PhD which focusses on the geometry and nature of inversion structures in the Irish Ore field and their impact on mineral deposits and associated mineralisation (under the supervision of Prof. John Walsh). General research interests include Ore-deposit geology and in particular structural controls on mineralisation.
My project focusses on how mineral deposits in central Ireland deform when two or more continents collide. Continental collision is a slow process whereby rocks deform over millions of years by either folding or fracturing. Newly available data allows me to build computer 3-dimensional models which illustrate how deformation has altered the shape of mineral deposits. Ultimately, a better understanding of how deposits deform allows us to more accurately interpret data for: 1) future academic research, 2) extracting metals in active mines and 3) exploring for new orebodies in Ireland.
Technical description
This research project uses newly compiled open-access and industry datasets, field mapping, 3D modelling, drill core sampling, petrographic analysis and published literature to explore four main topics relating to inversion: 1) How inversion is manifested regionally throughout the Irish Orefield, 2) how ore-controlling normal faults and lithologies have responded to inversion at the mine scale, 3) the links between various breccia’s and inversion-related deformation and 4) the effects of inversion on potential remobilisation of the mineralisation.
This study will provide insights into the principal spatial, rheological and temporal controls on the inversion of Carboniferous normal faults and associated mineral deposits. Ultimately, a more comprehensive understanding of how inversion is manifested will allow for better data interpretation for research, exploration targeting and mine evaluation.
