Abstract In regions formerly covered by continental ice, till sheets 05 contain distinctive clastic particles derived from local bedrock sources such as ore bodies. Such particles, especially in thicker tills, 05 be distributed in three-dimensional dispersal trains or plumes. Developments in our understanding of glacial erosion, entrainment, and deposition over the past two or three read more Genesis of dispersal plumes in till – R. Hooke et al.
