Capturing and preserving detailed information (geometry and any architectural ornamental features) of these structures can ensure long-term conservation and provide valuable resources for research, education, and future conservation efforts. Selecting appropriate methods and techniques for documentation to create a comprehensive 3D representation of the historic structure is always a subject of research, and it is a challenging issue, specifically if the site is in an area with security concerns. This research aims to evaluate the Digital Surface Model of the Minaret of Amedy, a heritage site that is nationally registered. The data collection process was planned and executed, involving an e-survey GNSS receiver for measuring ground control points and a total station (TS, Leica TS06) for measuring control points on the four sides of the Minaret. Two hundred three images were taken by UAV, DJI Phantom 4 pro manually flown, and 196 images using Nikon D5300. The data was processed using the Agisoft Metashape photogrammetry software to create the final 3D Surface model and orthophotos. The RMS errors gained from UAV orthophotos are presented relative to the TS. Sub-centimeter accuracy for horizontal and vertical positions was obtained at low flight altitudes. The 3D digital models’ accuracy of the Minaret was assessed using conventional survey measurements, resulting in a maximum standard deviation in the coordinates of ±2.4 cm. The relative accuracy in distance measurement ranged from 0.00% to 0.20% and 0.00% to 0.30% in the horizontal and vertical directions, respectively. In addition, the maximum inclination of the Minaret in the East and West direction is about 18 cm and 13 cm, respectively, which were observed. These results reveal that the finding is valuable for future intervention and further research.\u0000</p></div>","PeriodicalId":476,"journal":{"name":"Arabian Journal of Geosciences","volume":"18 10","pages":""},"PeriodicalIF":1.827,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145210224","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 aim was to decipher the nature, transport mechanisms, and paleodepositional environment. Four distinct lithofacies—L1, L2, L3, and L4—were identified. Observed data show L1 and L2 as normally graded, poorly sorted trough cross-bedded, and planar cross-bedded matrix-supported gravels, respectively, which were categorized as gravel bars and bedforms lithofacies association representing braided streamflow paleodepositional processes. Similarly, L3 is described as poorly-moderately sorted normally graded planar cross-bedded sand, while L4 shows intercalations of thin beds of mud and sand. L3 and L4 were thereafter characterized as laminated sheet sand and mud lithofacies association depicting sheetflood paleodepositional processes. The braided streamflow and sheetflood paleodepositional processes are hypothesized to depict a middle-outer alluvial fan gross depositional environment. This inference is supported by binary discriminant plots of parameters from statistical analysis of granulometry data from 12 representative samples and pebble morphometry data obtained from 111 gravels from L1 and L2. Furthermore, paleocurrent data, textural analysis, and mineralogy of framework depict textural immaturity and low compositional maturity, which indicate first-cycle sedimentation, sourced from the Precambrian rocks of the Igarra Schist Belt, north of the study area.

The biotite and two-mica granites are exclusively peraluminous in nature with S-type affinity, while the sanukitoids and the hybrid granites display both the I- and S-type characters with the metaluminous and peraluminous nature. The studied granitoids present negative anomalies in Nb–Ta, Pb and Ti suggesting the arc environment and the possible involvement of the subducted crust component to their formation. The isotope geochemistry results indicate heterogeneous source characteristics for the studied granitoids. The biotite and two-mica granites are from typical felsic crustal source, while the sanukitoids and the hybrid granites are from mixed older mafic crustal source with mantle component. The hybrid granites are formed due to interactions between the biotite and two-mica granites, the sanukitoids and the TTG. The geochemical and isotope systematics support a two-stage emplacement model for the Nalgonda granitoids as in the entire Eastern Dharwar Craton.

Therefore, this study aims to evaluate groundwater vulnerability through generic and modified DRAS-TIC approaches using the Geographic Information System (GIS) in the Borkena sub-basin, Awash River, Ethiopia. In this study, the standard DRASTIC model was improved through rating and weight modifications of the parameters and application of additional parameters, land use/land cover (LULC), and geological lineament density. The nitrate concentration was used in this study to validate the models’ accuracy. The correlation analysis between the nitrate concentration and the standard/modified DRASTIC models revealed that the most promising result (<i>R</i><sup>2</sup> = 0.76) was obtained when weight and rate modification were combined. According to the weight and rate-based modified DRASTIC Index, the study area was separated into very high, high, moderate, low, and very low susceptibility zones for groundwater pollution, with corresponding area coverage of 10.1% (165.8 km<sup>2</sup>), 22.6% (370 km<sup>2</sup>), 40% (654.7 km<sup>2</sup>), 22.9% (375.4 km<sup>2</sup>), and 5% (82.3 km<sup>2</sup>), respectively.

The study uses geological model to calculate sedimentation, tectonic subsidence, and the amount of eroded thickness resulting from tectonic processes in the sub-Hercynian, Laramide, and Alpine orogenies. The geothermal gradient is estimated based on decompacted formation thickness, revealing its influence on organic matter maturation in Zubair’s shales.
