Description :
Calcretes are widespread in the Adana region. X-ray powder diffractometry (XRD), scanning electron microscopy and energy-dispersive analyses (SEM-EDX) and differential thermal analysis-thermal gravimetry (DTA-TG) reveal that calcretes and their host-rock mudstones are composed predominantly of calcite and smectite, respectively. The results suggest a pedogenic origin for calcretes. The AA. estimate environmental conditions for calcrete formation : under the C3-dominated vegetation cover and semiarid or seasonally arid climatic conditions.
