ABSTRACT

Mineral resources exploration in the Kingdom of Saudi Arabia became an important target for the Saudi government. Nowadays, the economic vision of the country is to move away from oil-based country to multisource energy-based country. In Baljurashi area there were ancient mines for Copper, Cobalt, Magnesium, Zircon, and some other minerals. In the current study, we aim to evaluate the Baljurashi area in terms of mineral resources using the advanced technique. Consequently, we carried out ground gamma ray spectrometry survey in an area of about 50 km², elevation variation ranges from 380 m to 2280 m above the sea level. We used the RS-700 system to collect the gamma ray spectrometry data. In addition, we used the existing geochemical analysis results for this area and integrated the results to map the most important minerals. The integration work indicates that the area of Baljurashi is rich in mineral resources. The mineralization zones are located in the eastern part of the area where elevation is high (e.g., east of the escarpment). We also found that these mineralization zones are structurally controlled. Important mineral maps were produced (e.g. Cu, Cr, Mn, and Zr). We highly recommend more geophysical studies to evaluate the Baljurashi area for mineral identifications and quantifications.

摘要

沙特阿拉伯王国的矿产资源勘探成为沙特政府的重要目标。如今，该国的经济远景是从以石油为基础的国家转向以多源能源为基础的国家。在Baljurashi地区，有古老的矿山可开采铜，钴，镁，锆石和其他一些矿物。在当前的研究中，我们旨在使用先进技术从矿产资源角度评估巴尔久拉希地区。因此，我们在约50 km ²的区域内进行了地面伽马射线能谱测量，海拔变化范围从海拔380 m到2280 m。我们使用RS-700系统收集了伽玛射线光谱数据。此外，我们使用了该地区现有的地球化学分析结果，并对结果进行了综合，以绘制出最重要的矿物图。整合工作表明，巴尔朱拉希（Baljurashi）地区拥有丰富的矿产资源。矿化带位于海拔高的区域的东部（例如，悬崖的东侧）。我们还发现这些矿化带在结构上受到控制。绘制了重要的矿物图（例如Cu，Cr，Mn和Zr）。我们强烈建议进行更多的地球物理研究，以评估Baljurashi地区的矿物鉴定和定量。
