Notes on an interglacial deposit in Ballykeerogemore Townland and an interstadial deposit in Battlestown Townland, both in County Wexford

Abstract

Abstract:Ballykeerogemore: 6km south of New Ross, interglacial muds and silts (probably of Gortian age) were disturbed by ice (probably of Munsterian age) which thrust diamicts into them. The disturbed deposits were later partly buried by outwash (glaciofluvial) sands and gravels. Still later there was extensive development of ground-ice in the area, and many arcuate banks formed when the ground-ice melted.Battlestown: 3.5km south-east of Ramsgrange, there is a small enclosed basin in which weakly calcareous diamict (probably of Munsterian age) rests on rock. In the centre of the basin a thin layer of grey, laminated, pyritic, fine-grained material with a low content of organic debris with arctic affinities rests on the diamict. A feeble interstadial is suggested. The debris thins out upwards in a grey sandy clay-mud. Near the surface the material gains a content of small stones, possibly carried in by periglacial activity.
