However, the study of Hydrodiversity has been much less developed than other aspects of the geological heritage (lithology, mineralogy, geomorphology, paleontology). To evaluate the importance of Hydrodiversity, as part of geodiversity, and how it can condition the natural and cultural heritage of a region, a joint characterization of the hydrogeochemical and isotopic aspects of Los Hoyos area has been carried out. This is an evaporitic karst enclave of great environmental value, located in southern Spain. The main processes that explain the hydrodiversity of the area are (1) the availability of minerals in the environment, (2) the residence time of groundwater, (3) the evaporation of water in the wetlands, (4) the common-ion effect (5) and the high ionic strength of groundwater. All these processes, directly related to the geology and geomorfology of the area (Geodiversity), have given rise to diverse ecosystems (including protected wetlands), which enhance local Biodiversity, and geological forms (travertines) and are connected to the area's cultural heritage (salt extraction from the Paleolithic). The case here presented is an example of the importance of Hydrodiversity in the natural and cultural heritage and highlight the need of advancing in the definition and promotion of the hydrological heritage.","PeriodicalId":122881,"journal":{"name":"AgriSciRN EM Feeds","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125580907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The simulation involved two types of vein quartz crushed to fresh, angular grains of 0.5–1.0 mm fraction and arranged into dry, moistened and wet samples. Grain samples were subjected to fixed temperature oscillations (from -5°C to +10°C) under controlled laboratory conditions. Grain-size analysis were conducted after 50, 100, and 300 freeze-thaw cycles. Differences in the distributions, resulting from the production of the frost debris, were observed at each stage of the weathering process. Statistical analyses (Kolmogorov-Smirnov test, PCA, cluster analysis) demonstrated that both types of quartz grains react differently to the ongoing weathering process regardless of the moisture conditions. The production of very coarse- and coarse-grained sand fractions, resulting from the frost-induced destruction, was observed. This issue has never been addressed or expounded before. The production of fine and very fine-grained sands was notable while the silt-sized grains constituted only a minor product of the frost weathering. Nevertheless, the combined increase in the content of these fractions may have a significant impact on the properties of the frost-affected sediments/soils. The sample preparation (resulting in preparation defects) and the internal structure of quartz grains (resulting in primary defects) had a great influence on the initial course and manner of the frost weathering process. Other factors, such as availability or mineralization of water, exerted much less influence on the frost-driven destruction during the studied weathering period.","PeriodicalId":122881,"journal":{"name":"AgriSciRN EM Feeds","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130227554","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
