“…Calcium carbonate-rich limestone is especially prevalent in the area and is considered one of the area's most important natural resources. As calcium carbonate has many applications, [20], the percentage of calcium carbonate in samples collected from this area can reach 99.77 % and can be as low as 69 %, [19,21].…”

When two materials come into contact with one another, it is known that charges could be transferred from one surface to the other. This phenomenon is known as the triboelectric effect. The triboelectric series was developed in order to determine the likelihood of charge transfer when two materials come into contact with one another. This study aims to investigate the effect of calcium carbonate content in sedimentary rocks close to the city of Minia on the charge generated on the surface of the rock upon contact with another surface such as Kapton and polymethyl methacrylate (PMMA). The two materials were selected because Kapton is close to the bottom of the series, while PMMA is close to the top.It was found that a higher calcium carbonate content in a rock made it more likely to obtain a negative charge, thus lowering its position in the triboelectric series. Some rocks which are low in calcium carbonate with a few calcium carbonate-rich pockets on their surface induce a low charge on the surface they touch under a high contact force, due to the easy-to-break calcium carbonate pockets depositing calcium carbonate particles with an opposite charge on the other surface.

Geoheritage

Geodiversity, geoheritage, geoconservation, and geotourism insights are meticulously interrelated. Their investigations are of comprehensive attention worldwide because of their high scientific, educational, scenic, and recreational values. Various new destinations in Egypt have been promoted for the geotourism and abundance in significance geological heritages in which Samalute-Minia Area is one of the most energetic tourist’s magnetism. The study area is an imperative geo-cultural province that has significant number of geosites and geotouristic fascinations, demonstrating broad array of distinctive phenomena. The latter are assigned to remarkable geomorphological, volcanological, hydrogeological, quarrying, historical, and cultural landscapes that are deliberated a vital part of the polythematic geopark. All of these sites allow the visitors, sightseers, and indigenous populations to enjoy different aspects of tourism such as religious, antiquities, recreational, safari, or ecological tourism as the root for providing the commitment, education, and pleasure. The goal of the present paper aims to stress the reputation of the geological heritage earmarked by Samalute-Minia Area. A quantitative assessment of geodiversity at the study area was carried out using the Brilha’s method (2016) in which the evaluation outputs are labeled for geotourism obligations. A list of eight geosites has been inventoried. Among the principal geosites are (1) geomorphology and karst landforms (GKL), (2) circular structural landforms (CSL), (3) volcanic landforms (VL), (4) riverine landforms (RL), (5) Christian Religion sites (CRS), (6) ancient Egypt monuments (AEM), (7) industrial sites (IS), and (8) hydrogeological aquifers (HA). Quantitative valuation has been revealed that the bunched geosites of GKL, VL, and RL have great scientific and educational value scores, while the geosites of CRS and AEM have high potential touristic use compared to low value for the IS. Regarding the risk evaluation, a high degradation risk is assigned to the sites of AEM, RL, and HA. Severe threats comprising pollution, rapid urbanization, intense degradation of underground water, illegal water pumping, quarrying/excavation, bumpy tourism, and lacking of environmental management are the chief causes for the degradation risk. The lasting five geosites display a moderate to low risk of degradation because there are no extreme observed denudation processes that generate degradation. The protection and geoconservation, increasing the touristic attractiveness, and the socio-economic development for the local community could be proposed in order to decrease the high degradation risk for some geosites. Lastly, the Samalute-Minia Area needs more scientific and potential geoheritage study, improvement in the security circumstances, promotion of the geosites, and strategic implementations as well as regulation constraints for continuous regional development to improve geotourism and geoconservation. The geotourism development would diminish the rate of joblessness and immigration, offer scenarios for dropping poverty through engaging the local inhabitants in tourism activities, and ensure the protection and educational stopovers to well-known geosites.
