  • vegetation and general water balance, lithology and gradient). The relief position may allow an initial assessment of the relative age of the soil evolution. Profile classification and transport must be cross-checked with the laboratory analysis.
  • has been responsible for traditional continuous relief-forming processes also during following humid periods of the Holocene. Since the younger Holocene, erosion has been supported by anthropogenic influences.
  • is shown by micromorphological analysis and clay mineralogy. Distribution and origin of the soils are discussed in relation to the relief history.
  • to relief, despite the great petro-variation. The main reason is the intense chemical weathering under a climate similar to the tropical climate of today.
