ABSTRACT
Colca Valley located in southern Peru which forms one of the deepest canyon of the Word is the region of unquestionable nature values. The main goal of the study was to elaborate a complex assessment of the geodiversity the central part of this valley, using the multi-criterial, bonitation-parametric method. The following elements of abiotic environment were analysed: morphology, geological setting and waters. The relief analyse was made by describing types of natural landscape; morphologic landform, variability of relative heights and anthropogenic transformations. Presentation of the geology was elaborated with emphasis on lithology, tectonic and volcanogenic structures, presence and possibility of observing active geologic processes. By hydrosphere evaluation: streams; lakes, highland wets, waterfalls, springs, including springs of thermal waters and geysers were analyzed. All geotopes identified during the field work, were assessed and ranked (bonitation). The assessment, involving 3 groups of criteria: scientific values, use values and additional values. Such type complex geotope assessment of the Colca Valley seems to be the first one. Large number of specific criteria allowed to identify the most valuable criteria as well as to provide a wide-ranging assessment of geodiversity. The results of the study show the richness of geodiversity of Colca Valley region connected with its unique landscape values. The region is even more appealing as active geological processes can be observed here easily. Additionally the fame and interest associated with the canyon as well as possibility of watching here the condors, make this region particularly outstanding.The author expresses her hope that the presented results will provide some arguments for the protection of geological heritage of described region, giving the scientific base for future creation here the Colca Canyon Geopark.
