[Abstract] We describe the forming factors, properties, typology and distribution of soils developed over limestone in Galicia. According to the degree of development, three main tipes are distinguished. AR soils in high-erosion localities are decarbonated. AC soils formed by colluvial deposits of limestone material on, hillslopes have high carbonate levels, partly due to the greater solubility of unconsolidated material. ABR soils are found in relatively stable hillslope positions, in flat areas and cracks of rocks. Some are moderately well developed, with Bw horizons that have high carbonate content. Others are highly developed, with thick, totally decarbonated Bt horizons sometimes with low base saturation. The properties of all these soils depend on the degree of decarbonation.
