Abstract
Red soil or terra rossa is the most common soil type developed on carbonate rocks in the Kvarner area. In most cases, terra rossa has polygenetic origin and was formed by mixing of insoluble residue of carbonate rocks with weathered and eroded loess and flysch sediments. Climatic and glacioeustatic changes and tectonic movements during Quaternary have influenced recent position of terra rossa and its mineralogical composition. The recent position of terra rossa is a consequence of erosion. In the areas where tectonic movements were more pronounced, because of slope erosion and resedimentation-colluviation processes terra rossa is found in isolated depressions in the form of thicker depostits. Examples are northern part of Cres island and southern slopes of the Učka mountain. In the areas where tectonic movements were less pronounced terra rossa covers larger areas in the form of thinner deposits. An example is the western part of the island Krk.
