High-Resolution Magnetic Susceptibility Dataset from Borehole Samples from the “Rudnik” Mine Tailings, Republic of Serbia

In 2024, high-resolution (10 cm resolution) magnetic susceptibility (MS) data acquisition and subsequent sample preparation and laboratory measurements were conducted at the “Rudnik” mine tailing site in the Republic of Serbia. The dataset consists of 1010 measurements obtained from 7 boreholes, with the largest borehole containing 218 continuously measured MS samples and the smallest containing 103 measured values. The dataset includes mass magnetic susceptibility data from seven boreholes, accompanied by lithological descriptions of the respective samples and measured sample mass data. High-resolution MS data were obtained during the characterization phase of flotation tailings, as the MS technique is established as an effective proxy for detecting heavy metals in tailings, while also being cost-effective, straightforward, and rapid. Consequently, researchers can acquire extensive data which is correlated with heavy metal concentrations while reserving costly and time-intensive chemical analyses only for the most relevant samples obtained by the analysis of MS values. The significance of such datasets resides in their ability to foster transparency and collaboration, thereby facilitating cross-disciplinary research that may enhance the methodology of the MS technique. In addition to its direct geophysical applications, the dataset fosters transparency and interdisciplinary collaboration, allowing geoscientists, statisticians, and data scientists to evaluate and refine methodologies that could improve the efficiency of the MS technique in the future.
