Stone Line Technical Terms
Stone Line: In vertical cross-section, a line formed by scattered fragments or a discrete layer of angular and subangular rock fragments, commonly a gravel- or cobble-sized lag concentration that drape across a former topographic surface and later buried by additional sediments. A stone line generally caps material that was subject to weathering, soil formation, and erosion before burial. Many stone lines seem to be buried erosion pavements, originally formed by sheet and rill erosion across the land surface. It can best be observed as outcrops in natural and artificial cuts. Also called a carpedolith. Compare - erosional pavement, desert pavement. SW & RR
