Abstract
White hydrogen has recently significant attention as a potential low-carbon energy source. This study aims to identify hydrogen-related geological processes in Semeru^s Volcanic through magnetic susceptibility and spatial mapping of Fe2O3. Magnetic susceptibility can be used as a proxy indicators for identifying in iron-bearing mineral within geological materials. Based on compiled data, the linier regression analysis was applied to evaluated the correlation between low-frequency magnetic susceptibility (𝜒-𝑙-𝑓-) with Fe2O3 concentration. The statistical results a Pearson correlation coeficient (r = 0.755) and a coefficient of determination (R2=0.0570), indicating a moderate to strong positive correlation between both parameters and has suggested that approximately 57 % of the variability in iron oxide phases controls the magnetic response significantly. The contour mapping based reanalysis of compiled geochemical data of Fe2O3 distributions in Semeru, have shown a low results with smooth gradients, indicating that limited oxidation and alteration have occurred on surface area. The spatial distributions pattern has reflected a subsurface in volcanic system controlled by fluid migration and low magnetic susceptibility zones can be interpreted as white hydrogen fluid migration pathways. This correlation demonstrates that geochemical spatial of Fe2O3 and magnetic susceptibility analysis can be used as a relevant proxies to identify the distribution of white hydrogen.
