## 1 Introduction
In the last decade, the investigations regarding geosites/geomorphosites have used diverse quantitative and qualitative methods, according to ideas based on the conservation, protection and use of geological/geomorphological heritage. These studies propose criteria for the classification and characterization of the researched geological heritage [39; 40], the assessment of geomorphosite scientific quality [41], the classification of geomorphosites according to their tourism value [42], the parameters for the inventory and evaluation of the geomorphosites [43], the assessment of geomorphosites by means of scientific and additional parameters [44], and the analysis of intrinsic qualities, as well as the usefulness potential of the studied geomorphosite [1], as well as taking into consideration the possible threats and providing solutions for a better protection [45], techniques for geomorphosite assessment [9], a quantitative method used for the evaluation of geotopes, which can also be used for the sustainable management and the conservation of geological heritage within the study area [46; 47]. Based on sets of criteria and indicators for determining values of the analysed site [48], the purpose of using these methods is to facilitate the site assessment, so that the researcher may easily determine the aspects provided by the analysed landform, and then may perform a ranking of the sites and place them according to the importance and priority they have within the processes of research, planning and protection [49; 50]. Geomorphosites have been approached since the 1990s. In time, many definitions of the term geomorphosite have been provided. [PERSON] et al. [51] and [PERSON] [52; 53; 54] consider this term to be any geological form which receives subjective value from the perspective of the researcher, whether a scientific, aesthetic, cultural-historical or economic one. [PERSON] [55] considered that geomorphosites represent the geomorphological assets of geological heritage to which certain values may be attributed. Later, he provided another definition, stating that geomorphosites represent landforms that have peculiar and significant geomorphological features that qualify them to be components of cultural heritage [56; 57]. [PERSON] [58] considers that the scientific value of the geomorphosite is the main value, while all the other types of values are secondary values. The total amount of values represents the global value of the geomorphosite. [PERSON] and [PERSON] [59] define this term as being an essential element within protected natural areas that should be assessed both for its scientific value, and for its social and economic impact. Geosites, like geomorphosites, represent those landforms that constitute elements of scientific, cultural, economic, historical, and socio-cultural diversity, and on which quantitative and qualitative evaluations can be made [60]. Nature conservation has become a subject of scientific interest since the 1970s [60], while geodiversity conservation has become a strategy of global importance since the 1990s, especially after the first international symposium for the conservation of cultural heritage [61]. Geodiversity addresses aspects related to natural geological and geomorphological elements and soil features [62]. Conservation programs, well-known at the international and national levels (UNESCO Cultural Heritage, Natura 2000 Program) [63], encompass the protection of the entire natural habitat, defined by the geographical and ecological conditions of the environment [64; 65]. The geological strata present interest in the assessment of geosites/geomorphosites due to changes occurring in time as a result of the actions of geomorphological processes on rocks, but also due to human intervention. Changes lead to the appearance of negative aspects (vulnerabilities) within the analysed landform, which may determine the destruction of the site (risk), unless stopped by measures taken by specialists [12].
