Abstract: The subject of this thesis is to identify mineralogical, geochemical and pedophysical properties of polygenetic soil de-veloped on late glacial loess on the island of Susak. In addition to this, the purpose was to determine the age of two loess hori-ozons within the investigated soil profile. Loess is clastic aeolian sediment, usually accumulated during the colder periods of Pleistocene. Since loess is particularly dependant on climatic conditions, it is being widely used as a proxy in Quaternary paleo-climatic reconstructions. In April 2014. a five day field work was organised on the island of Susak with the purpose of sampling. The focus was put on the top part of Susak loess sequence, and location ”Svjetionik” (Lighthouse) was investigated in detail. Since most of the paleosols within loess sequence contain secondary pedogenetic carbonates, which could “conceal” certain pedogenic processes, it was necessary to find a carbonate-free soil. During field work, morphological properties of soil horizons were investigated. Based on field and laboratory investigations we concluded that soil situated on the top of loess sequence repre-sents polygenetic soil. Chemical, physical, geochemical, granulometrical and mineralogical properties of loess and polygenetic soils were determined. Loess sedimentation age was determined by infrared stimulated luminescence (IRSL). Investigated prop-erties of loess and polygenetic soil allowed a detailed reconstruction of pedogenic processes which formed the investigated poly-genetic soil. Four important conclusion came out from this thesis. (1) Investigated soil is polygenetic. Two loess horizons and developed paleosol horizon Bb (whose parent loess material is no longer present in soil) clearly point out the polygenetic nature of investigated soil. (2) Stratigraphically youngest loess horizons were determined. Determined age of loess located at the base of polyge-netic soil is ~16 000 ka, belonging to OIS-2, while overlying younger loess is ~3 000 ka old. (3) Geochemical and mineralogical properties clearly singled out paleosol horizon Bb, in which presence of chlorite-vermiculite indicates substantial weathering of primary phyllosilicates. Furthermore, high values of CEC, Fed / Fet and CIA clearly point out that Bb paleosol has undergone the most significant pedogenic change. (4) Presence of loess, paleosol and modern soil in the polygenetic soil profile indicate that generally warm and humid climate of actual interglacial was interrupted with colder and drier periods with stronger winds. Using elemental geo-chemistry, a comparison between modern and past climate conditions (temperature and precipitation) was made
