Abstract
⺠Stable isotope compositions of non-pedogenic calcretised wadi deposits studied. ⺠Effects of hydrology, topography, vegetation, diagenesis, time, and climate assessed. ⺠δ18O and cement type show how calcrete form is affected by position in channels. ⺠Negative δ18O calcrete values suggest formation under low evaporative conditions. ⺠Similar distribution of modern C3 & C4 plants and the δ13C signatures of calcretes.
