Roisin Kyne is a Post-Doctoral Research Fellow in the iCRAG raw materials spoke. Roisin graduated with a PhD in structural and economic geology from CODES (ARC-Centre of Excellence in Ore Deposits), University of Tasmania, in 2014 before joining the iCRAG team in 2015. At iCRAG, Roisin’s research focuses on 3D modelling of Irish Carboniferous Basins at regional and mineral deposit scales. Specifically, by integrating various data sets (i.e. borehole, seismic, mapping, etc.) from across Ireland, this research will produce renewed insights into the structural evolution of Irish-style Zn-Pb mineralization. General research interests include structural/tectonic geology, petrology and mineral analysis.
The Irish Zn-Pb ore field is world renowned for the nature of its mineralisation and for the structural and stratigraphic control on the localization of that mineralisation. Ireland is a major player in the raw minerals industry, representing the largest zinc producer and second largest lead producer in Europe. Since the December 2015 closure of one of Ireland’s two Zn-Pb producing mines (Lisheen), the importance of mineral exploration has become critical. However, the discovery and management of raw materials in Ireland has become increasingly difficult with likely targets (based on current 2D models) occurring at greater depths within the subsurface. The 3D Ireland platform has been designed to directly address this issue by producing detailed 3D structural and stratigraphic models (from the regional down to the local scale) using state-of-the-art modelling techniques.
These models will be produced in an effort to better understand the formation and controls of the Irish-type deposits and to identify key, recognizable characteristics of these types of deposits.
Historically, workers in the Irish ore field have linked the presence of normal faults with the formation of individual deposits. Like many deposits around the world, these historical findings were gleaned from field observations and 2D analysis without the benefits of a 3D perspective. Fusciardi et al., (2004) were the first to recognize the importance of segmentation, relay ramps and fault zone complexities6 on the formation and localization of the Irish-type deposits. These findings highlight the importance of a 3D perspective when attempting to understand the formation of deposits and draws attention to the need for high quality, 3D models of the structures and stratigraphy, which control associated mineralisation. Building on the existing national database retained by the GSI and utilising data and current 3D models donated by industry partners, the 3D Ireland platform will address current industry problems relating to efficient/effective target identification by developing refined 3D geological models for the Irish Carboniferous, and associated Zn-Pb deposits. This research will underpin both future exploration efforts as well as future associated research projects.
