The granite and limestone wastes are pelletized into different grain sizes and then dried for 48 hours in open air at room temperature to remove the excess water and enhance workability. Subsequently, the pellets are fired in a rotary kiln at a very high temperature, with a heating rate of 20°C per minute, for 2 hours at 1100°C. The chemical and mineralogical composition of the waste materials is analyzed using techniques such as petrography, X-ray fluorescence (XRF), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). These analyses show the composition and structure of the first material which is granite with a high iron content (6.66%) is called “Ferriferous granite”, the second material is granite with normal iron content (3.15%) is called “Normal granite” and the third material is “Limestone”, and aid in the selection of suitable materials for concrete production. In conclusion, this research aims to investigate the potential use of granite and limestone waste materials as replacements for traditional aggregates in concrete production. Through a series of shaping, burning, and mixing processes. The important results obtained is that as the percentage of granite waste increases, the pellets become more friable. Therefore, based on this research, we recommend mixing the granite and limestone to enhance the durability of the aggregates, enabling their utilization in the production of high-strength concrete.","PeriodicalId":282322,"journal":{"name":"Egyptian Journal of Geology","volume":" 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138613172","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 basement rocks include metavolcanics and enormous plutons of granitoid rocks. The metavolcanics are regionally metamorphosed, forming greenschist to amphibolite facies rocks interbedded with banded iron formation (BIF). Structural analysis in the Umm Anab metavolcanics (UAV) indicates that the area has a poly-phase structural deformation, and each phase has its own effect and style. A Well-developed schistosity striking approximately E-W with dipping 60º-80º southward, and asymmetrical folds with oblique subvertical NNW-striking axial planes were observed. The structural analysis of the veins in metavolcanic by using GArcmB software determined the paleostress inversion and displayed two clusters of veins that formed under two stresses. The stress ratios ( Φ )= ( σ 2 – σ 3) / ( σ 1 – σ 3) for both clusters, respectively, are ~0.39 and ~0.16, which shows two stress status. The values of the stress ratio on vein walls suggest that the host rock was subject to low to moderate tectonic stress at the time the veins formation. In addition, finite strain results in metavolcanics were estimated using the Rf/φ method on deformed pebbles (with a trend of N73º-88ºE), confirming the idea that metavolcanics are affected by low to moderate deformation. The stretching mineral lineation and BIF have trend ENE-WSW to E-W that supports the oldest shortening event (D1) which is considered an early phase of deformation NNW–SSE linked with the Pan-African thrusting.","PeriodicalId":282322,"journal":{"name":"Egyptian Journal of Geology","volume":"94 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138621772","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}

It is a residential area suffering from unplanned industrial activities, overpopulation, and uncontrolled urbanization. Heavy metal sources and geochemical associations were deciphered using a multivariate statistical approach, while the contamination degree and ecological risks were identified using various pollution indices. Moreover, the human health risks (carcinogenic and non-carcinogenic) for residents were estimated via different exposure pathways. The mean abundances of elements were as follows: Fe > Mn > Zn > Cr > Cu > Pb > Mo > Co, while the individual contamination grades decreased in the following order: Mo > Cu > Zn > Pb > Cr > Fe > Mn > Co, according to the geoaccumulation index (I geo ) and the contamination factor (CF) average values. The high correlation between Zn and Cu ( r = 0.92) reflected their common origin (traffic-related emissions). Notably, only Cu showed individual ecological risk; meanwhile, the overall ecological risk index (RI) classified the study area as having low ecological risk (RI < 150), with an average of 75.20. The health risk assessment indicated the absence of adverse non-carcinogenic risks and the presence of unacceptable carcinogenic risks posed by Cr and Pb. Ultimately, heavy-duty vehicular emissions (e.g., tire and brake wear) and industrial emissions from cement and refining companies are likely the main contributors to heavy metal loadings in the study area. The results of this research will be useful in developing strategies for pollution control and management and can be utilized for comparison in future studies.","PeriodicalId":282322,"journal":{"name":"Egyptian Journal of Geology","volume":"102 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138608836","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}

While faraway about this area it is problematic to delineate the reservoirs, due to the low reflectivity that produced by the huge thickness of Pliocene shales.
