Clay cutan
Clay Cutans are a geologic fabric that develop around ancient cavities (such as peds) within paleosols. == Formation == Clay Cutans form by the coating of ancient open spaces by colloidal materials that were elluviated down from overlying horizons - and are commonly stained by iron oxides such as hematite. While the originally openings are commonly lost through geologic time and diagenesis, the cutanic fabric remains as evidence. Cutans also often contain relics of nodules and skeleton grains. 〔Retallack, G.J., 1988. Field recognition of paleosols. In: Paleosols and weathering through geologic time: Principles and Applications, Reinhardt, J. and Sigleo, W.R. (eds.). Geological Society of America, Special Paper, 18 pp. 〕 They are one of the most diagnostic features of paleosols.
