Abstract
Boreholes drilled in the Wexford Outlier have proved Permo‐Trias conglomerate and red beds (Killag Formation), Westphalian D sandstone and mudrock. including at least one thin coal (Richfield Formation), and probable Namurian mudrock (Park Formation). The Killag Formation rests on the Westphalian, the Namurian, and on Dinantian (probably Asbian) limestone in different boreholes. The Westphalian contains horizons with bivalves, conchostracans, and plants and has yielded miospore assemblages which, in addition to indigenous taxa, contain reworked material of three different ages: Devonian or early Carboniferous; late Viséan or early Namurian; and Westphalian A. The western end of the Welsh massif of previous palaeogeographical reconstructions was of very low relief during the Silesian and probably was more often a site of deposition than of erosion.
