Abstract

The AA. present detailed sedimentological and geophysical investigations of ramparted depressions from Llanpumsaint, Wales. These data are used to establish internal structure and to evaluate possible mechanisms for landform formation. Borehole and geophysical data have revealed a thick sequence of glaciolacustrine sediments beneath the study site. The rampart deformation structures are consistent with 2 models, but units of sand and gravel within the ramparts favour a hypothesis that these landforms represent the collapsed remains of ground-ice mounds. This study highlights the importance of recognising and evaluating all possible (periglacial and non-periglacial) models for the development of ramparted depressions
