  Abstract:  This research concerned three profiles developed on Eocene (Priabonian) gypsum parent material from Stana (Cluj district) in order to investigate their properties. The soil and parent material samples were collected from individual horizons in each profile. Both the mineralogical and structural-textural features of the parent material (evaporitic deposits) reflect the depositional context. From a mineralogical point of view, the deposits are represented by gypsum, and anhydrite. Typical sulfate facies are present: laminitic, nodular, gypscretic, and entherolitic. Physical and mineralogical properties of the soil layers were determined in the laboratory. The field observations and the results of the analyses allowed us to classify the soil as a rendzinic regosol, according to the Romanian System of Soil Taxonomy (S.R.T.S. 2000).
