Soils in an Aridic, Ustic, Udic, Climosequence in the Maracaibo Lake Basin, Venezuela

Abstract Eight profiles developed from parent materials with low contents of weatherable minerals retained remarkably similar mineralogical suites regardless of soil moisture regime although some mica weathering was detected in the udic soil moisture regime. Sola thickness exceeded 2 m in all profiles. Base saturation percentages increase with depth in the B horizons of the soils in the aridic and ustic soil moisture regimes and clearly decrease with depth in the udic soil moisture regime.
