Eat significance to combine the HAZs and extracted fracture/fault zones for prospecting possible locations of hydrothermal mineral sources. Thus, in this study, we focus on combining remote-sensing, geologic, field, and laboratory data sets to delineate the prospective regions of hydrothermal mineral sources and create a extensive scheme that would IQP-0528 Cancer facilitate future exploration for hydrothermal ores inside the Eastern Desert (ED) of Egypt. 2. Study Area The study encompasses a 119-km2 area bounded by latitudes 26 19 44.38″and 26 24 50.93″N, and longitudes 33 23 35.86″and 33 31 12.33″E (Figure 1a,b). It is situated about 20 km southeast of Qena-Safaga road (at kilometer 85). The study location is a part of the Arabian Nubian Shield (ANS) that covers wide locations of Egypt, Saudi Arabia, and Sudan, where “ophiolitic m ange” (serpentinites, metagabbros, mafic metavolcanics), “arc assemblages” intermediate-acidic metavolcanics, and metasediments of the Proterozoic age are exposed. These assemblages are intruded by “syn-tectonic granites” calc-alkalic granodiorites or tonalites (older granites) which can be subjected to strike-slip faults, promoting deposition of Hammamat sediments in small elongated basins. The whole sequence is intruded by “late-post tectonic” alkali granites (younger granites) and felsic and mafic dikes that most likely trend NW-SE. Mining at this web page was related for the New Kingdom. A lot of the gold associated with quartz veins had been mined in open-cast and deep mining tactics [28]. In contact having a quartz vein, the granodiorite hydrothermally altered to a sericite quartz rock [28,29]. The fracture/fault zones that cut the study region are NW-SE, NNW-SSE, N-S, NNE-SSW, and NE-SW. By far the most prominent trends of fracturing occurred along the NWSE, NE-SW, and N-S directions. Younger granites are cut by quite a few fracture/fault zones in the NNW-SSE, NE-SW, and N-S directions.Remote Sens. 2021, 13, x FOR PEER Review Remote Sens. 2021, 13, 4492 Remote Sens. 2021, 13, x FOR PEER REVIEW3 of 20 3 of 20 3 ofFigure 1. place map (a) Regional geologic map the ANS in Egypt showing the distribution of of gold mines as solid Figure 1.
