Magmatic studies group 

General Research Area

The Magmatic Studies Group uses multidisciplinary approaches to investigate the petrogenesis of carbonated and carbonate-rich igneous rocks (both locally and internationally), the magmatic phenomena occurring on the Palaeozoic sea floors of Ireland, and the formation of ore mineralizations associated with magmatic activity. 

Disciplines

field geology, petrography, geochemistry, numerical and experimental modelling, and fluid inclusion studies (in collaboration with the Geofluids Research Group)

Group Leader

Kathryn Moore 

Explosive dyke cross-cutting Carboniferous strata, White Ball Head, Beara Peninsula, Co. Cork.	Outcrop of the core of a diatreme pipe at Black Ball Head, Beara Peninsula, Co. Cork.

Brief description of current projects

Carbonatite magma mingling and mixing: investigations including petrography and geochemistry (in collaboration with Professor Frances Wall as above and Dr Farid Divaev of the Institute of Mineral Resources, Tashkent, Uzbekistan), and numerical modelling (in collaboration with Luca Valentini, University of Perugia, Italy)

The role of carbonate in diatremic magmatism: student research project (Aoife Brady) investigating the chemistry of carbonate minerals; in collaboration with Professor Frances Wall (Camborne School of Mines, Cornwall, UK) and Professor Troels Nielsen (Geological Survey of Denmark and Greenland,Copenhagen, Denmark).

Carbonatite magma genesis in orogenic and post-orogenic tectonic settings: numerical modelling investigation in collaboration with Professor Paul Ryan, NUI Galway, Ireland.

Mechanisms of explosive emplacement of subvolcanic magmas: field investigations assisted by the undergraduate students of NUI Galway.

Explosive Magmatism, Peperites and Magma-sediment Interaction at the Bunmahon Volcano, County Waterford: student research project (Catherine Breheny) investigating the relationship between ocean floor magmatism and ore deposits on the Copper Coast; in collaboration with Dr Martin Feely, NUI Galway, Ireland.

Volcanology and petrology of arc magmatism in South Mayo: comparative stratigraphy of convergent margins. Student research project (Zara Archibald) investigating the relationship between basalt chemistry, eruption phenomena and lava morphology of the Ordovician Bencorragh Formation in Finny.
