The South Munster Basin of southwest Ireland

Abstract

This paper presents a geological map at a scale of 1:75,000 of an area of about 3,500km 2 of the western part of the Devonian and Carboniferous South Munster Basin of southern Ireland. The compilation utilised existing geological data from a variety of sources in association with recent mapping. Aerial photographic data were used extensively to identify structural features not previously mapped. Geological and selected topographical information were scanned to a computer and the final compilation map was digitised using Macromedia Freehand software at a scale of 1:3,125. The map was subsequently converted to a scale of about 1:75,000.

The vein-hosted copper deposits of the Allihies mining area, SW Ireland; a new structural and chronological evaluation

“…Large E-W faults, such as the Coomnacronia-Killarney-Mallow Fault Zone and the Cork-Kenmare Fault Zone (Fig. 1, Naylor & Jones 1967;Capewell 1975;Price & Todd 1988;Vermeulen et al 2000;Landes et al 2003;MacCarthy 2007;Ennis et al 2015) played an important role in the development of the Munster Basin. These major faults are part of a southwards progressing extensional fault system (Landes et al 2003).…”

“…Towards the end of the Devonian the formation of another east-west trending fault system, the Cork-Kenmare Fault Zone (Fig. 1) resulted in continuous subsidence of the South Munster Basin (MacCarthy 2007). This was accompanied by a marine transgression from the south with resulting accumulation of marine siliciclastics within the South Munster Basin and limestones on a more stable platform to the north (Fig.…”

“…The northern bounding structure of this intracratonic basin has been described as the east-west trending, listric Coomnacronia-Killarney-Mallow Fault Zone (Fig. 1; Naylor & Jones 1967;Capewell 1975;Price & Todd 1988;Vermeulen et al 2000;Landes et al 2003;MacCarthy 2007;Ennis et al 2015) or the Dingle Bay-Galtee Fault Zone Williams (2000).…”

Occurrence, characteristics and formation mechanisms of methane generated micro-pockmarks in Dunmanus Bay, Ireland

“…The bedrock geology of Dunmanus Bay has not been studied per se but inferred from the geology of bordering landmasses in the 1850s by Jukes (1864) and Jukes et al (1861) and more recently by Naylor (1975), Naylor and Sevastopulo, (1993) and MacCarthy (2007). Both Bantry and Dunmanus Bay lie in the South Munster Basin separated by the Sheep's Head anticline.…”

Remobilization and mineralization of selenium–tellurium in metamorphosed red beds: Evidence from the Munster Basin, Ireland

“…A detailed account of the sedimentology and stratigraphy of the Old Red Sandstone in the Munster Basin was covered by MacCarthy (1990;2007), Kelly & Sadler (1995), and Pracht and Sleeman (2002), thus a summarised overview is given here.…”
