“…This led to a marine transgression into the basin from the east during the Famennian, which advanced in a westerly direction along the axis of the South Munster Basin (MacCarthy, 1987) and terminated Old Red Sandstone deposition in this area. Previous sedimentological studies ofthe non-marine basin fill have been mainly of a localized nature (Capewell, 1957(Capewell, , 1975Kuijpers, 1972;Graham & Reilly, 1972, 1976Graham, 1975;MacCarthy, Gardiner & Horne, 1978 ;Bridge, Van Veen & Matten, 1980;Penney, 1980;Ori & Penney, 1982;Bridge, 1983;Bridge & Diemer, 1983;Gardiner & Horne, 1983;Diemer, Bridge & Sanderson, 1987;Todd, 1989;Williams et al, 1989) though a few studies have formulated models for regional alluvial processes within the basin (Gardiner & MacCarthy, 1981;Graham, 1983). Of necessity, these are generalized due to the wide spread of the limited control points available at the time, allied with poor biostratigraphical control and the absence of a detailed lithostratigraphical framework.…”
