Ablah area is a basin among the deformed and weakly metamorphosed, post-amalgamation volcanosedimentary sequence in the Arabian shield, Saudi Arabia. It is a promising area for some economic deposits. This study aims to construct a detailed geological map and rock unit discrimination of the area, using digital image processing techniques. The satellite digital data comprise Landsat-7 and SPOT-5 are used for regional, reconnaissance, and detailed geological mapping. The high spatial resolution (HR) digital data of SPOT-5 were processed to create a detailed lithologic and structure maps of the study area (1:10,000). The outcomes of the work reflect that the mineralization in the Ablah area (e.g., gold, copper, and associated minerals) are mainly associated with the altered metasediments and metavolcanics. The alteration zones in the Ablah area are aligned in a way controlled by structural lineaments trending NNW-SSE, WNW-ESE, NE-SW, and N-S.

Ablah地区是沙特阿拉伯盾牌中变形和弱变质后融合后火山岩沉积序列中的一个盆地。这是一些经济存款的有希望的领域。这项研究旨在使用数字图像处理技术来构建该地区的详细地质图和岩石单元判别方法。包括Landsat-7和SPOT-5在内的卫星数字数据用于区域，侦察和详细的地质制图。处理SPOT-5的高空间分辨率（HR）数字数据以创建研究区域的详细岩性和结构图（1：10,000）。这项工作的结果表明，阿布拉地区的矿化（例如金，铜和相关矿物）主要与变质沉积物和变火山作用有关。
