WebThe term "Lithological discontinuity" (from Greek lithos, stone, and Latin continuare, to continue) refers to significant changes in particle-size distribution or mineralogy that represent differences in lithology within a soil. A lithological discontinuity can also … Web1 jan. 2014 · Lithologic discontinuities may affect water movement, leading to the formation of bisequal soils with a spodic profile over an argillic profile (Bockheim 2003). Podzolization, possibly initiated by a change in climate and vegetation, degrades the argillic horizon. “Albeluvic tongues” may form in 4,600–6,200 yr (Sauer et al. 2009).
