In this research, airborne geophysical and remote sensing datasets were integrated for gold potentiality mapping (GPM) over the Atalla area in Central Eastern Desert, Egypt. Utilizing aeromagnetic data, detailed structural complexity maps were constructed using the center for exploration targeting (CET) procedure. Then, spectrometric gamma-ray data primarily located hydrothermally altered tracts with discriminating various rock units. The latter are precisely outlined by implementing various techniques (false-color composite (FCC), band ratio (BR), relative absorption band depth (RBD), directed principal component analysis (DPCA), and constrained energy minimization (CEM)) to ASTER, Sentinel 2 and ALOS PRISM datasets, with reference to the geological maps. The study exhibits that gold mineralization is structurally controlled by NW-SE direction. The findings of structural complexity and hydrothermal alteration (argillic, advanced argillic, phyllic, and propylitic) were used as weighted inputs for contouring gold potentiality. The resultant GPM accentuated five gold-promising zones; two are confirmed via locations of ancient gold mines, while the remaining three zones are strongly recommended for their gold potentiality.

埃及中东部沙漠阿塔拉地区及其周边地区黄金潜力测绘的多源数据分析

在这项研究中，航空地球物理和遥感数据集被整合在一起，用于埃及中东部沙漠阿塔拉地区的黄金潜力测绘 (GPM)。利用航磁数据，使用勘探目标中心 (CET) 程序构建了详细的结构复杂性地图。然后，光谱伽马射线数据主要位于热液蚀变区域，可区分各种岩石单元。后者通过对 ASTER 实施各种技术（假色合成 (FCC)、带比 (BR)、相对吸收带深度 (RBD)、定向主成分分析 (DPCA) 和约束能量最小化 (CEM)）来精确概述, Sentinel 2 和 ALOS PRISM 数据集，参考地质图。研究表明，金矿化在结构上受 NW-SE 方向控制。结构复杂性和热液蚀变（泥质、高级泥质、叶质和青质岩）的发现被用作绘制黄金潜力轮廓的加权输入。由此产生的 GPM 突出了五个有希望的黄金区域；两个是通过古代金矿的位置确认的，而其余三个区域因其黄金潜力而被强烈推荐。
