    Abstract

    Vadose calcretisation commences with precipitation of micritic calcite from carbonate-rich meteoric water in the soil moisture zone. Through time, calcrete is subjected to repeated episodes of vadose cementation, dissolution, and brecciation of earlier-formed soil components, giving rise to stratigraphically complex soil profiles. The degree of complexity of individual profiles is largely influenced by the geomorphological setting and hydrological history of the local groundwater systems. Assessment of the timing of the main phases of carbonate precipitation indicates that calcrete soil profiles can attain maturity within a relatively short time.
