Soil welding is the formation of the solum of a ground soil through a thin cover sediment and mergence with the solum of a buried soil formed in a substratum material. Welding complicates field recognition of boundaries between materials and sola. Analyses of physical and mineralogic properties in the laboratory may help to resolve the field problems, but chemical properties may not be useful. Failure to recognize soil welding leads to improper interpretation of the pedologic development of ground soils and improper deciphering of soil stratigraphy in the Quaternary.
