“…The existence of Arjuno-Welirang is associated with geothermal potential. Geothermal manifestations are found in the form of Plupuh crater fumarole, which can be found at the top, while hot springs can be found in Padusan and Cangar, which are bicarbonate-type (Baud et al, 2021;Maryanto et al, 2020). The series of rocks that make up Mount Arjuno-Welirang consists of volcanic breccia, lava, tufan breccia and tuff (Santosa & Suwarti, 1992).…”

Mount of Arjuno-Welirang has a geological structure consisting of volcanic breccias, lava, tuff and tuff breccias. This study aims to determine the chemical element content of the igneous rocks constructed on Mount Arjuno-Welirang. X-ray fluorescence (XRF) analysis of 7 samples showed the presence of Al, Si, P, K, Ca, Ti, V, Cr, Mn, Fe, Cu, Zn, Sr, Ba, Eu, and Re. The dominant elements (Wt% >10%) from high concentrations are Si, Al, Ca, and Fe. In addition, we also found Rare Earth Element (REE) Europium (Eu) content with an average of 0.23Wt%. SiO2 compound is larger than the Bromo-Semeru volcanic material, while K2O is larger than the Semeru volcanic material and smaller than Bromo. Meanwhile, the Fe2O3 compound is taller than that of Bromo-Semeru. Based on the Hutchinson formula, the depth of the magma source is determined in the range of ± 147.7 km to ± 225.1 km below the surface. Depth data also significantly affect several oxide compounds, such as K2O, V2O5, and ZnO, with correlations of .942**, − .747*, and − .936 **, respectively. The significant correlation shown is only the correlation with K2O, which offers a considerable correlation relationship with a positive trend.

“…Volcanic rocks have complex variations and characteristics in terms of shape, grain size, mineral content, and distribution (Rüpke et al, 2002;Schaefer and Kattenhorn, 2004;Pratama et al, 2018). Hydrogeology systems in volcanic settings result from various interactions and processes that are influenced by the characteristics of minerals and rocks (Delcamp et al, 2016;Baud et al, 2021). However, the study of the geological context of hydrogeological system occurrences is not given specific consideration.…”

Indonesia is located in a subduction zone formed by the collision of continental and oceanic plates. Many volcanoes form as a result of these conditions along the arc. Springs on the volcano's slopes are widely used for domestic, irrigation, and industry water use. Investigating the characteristics of aquifers and springs is essential to ensure groundwater sustainability by providing a robust geological framework. Meanwhile, groundwater in a volcanic geological setting has good quality characteristics because of its occurrence process, which interacts with many minerals in pyroclastic rocks that act as aquifers. The study area is located in the Lido Catchment Area (LCA), which is situated between two distinct volcanic slopes. Geological and morphometric analysis at LCA is the basis of important information relating to its hydrogeological systems. The analysis of thin rock sections and parameters of the physical properties of water in groundwater springs supports our research. We applied a comprehensive geological and morphometric analysis to obtain detailed information about the aquifer. This study aimed to determine the characteristics of aquifers in pyroclastic rocks and their relationship to the formation of springs. From the research conducted, the characteristic of water can be distinguished based on the geological conditions of its constituents. There are 6 different lithological characteristics in the study area: polymictic breccia, monomictic breccia, lapilli, lapilli tuff, coarse tuff, and fine tuff. From the lithology variations obtained, breccia, lapilli, and coarse tuff can play a good role as aquifers. Geological correlations and groundwater systems in the study area show groups of superficial, mixed, and alteration springs. The system of water flows in aquifers through inter-grains or rock fractures. The types of springs in LCA are dominated by depression and fracture types. These results are fundamental information for understanding hydrogeological systems in future volcanic geological settings.

“…This plays a vital role, and sustainable management is necessary. It requires aquifer configuration, hydrogeochemical and hydro-isotope data, groundwater fluctuations, usage, and quality (Hadian et al, 2016;Toulier et al, 2019;Baud et al, 2021).…”

Merapi Volcano, which differs from volcanoes in other climates due to its location on the Indonesian Maritime Continent influenced by ENSO, ICTZ, and Moonsons, plays an essential role as a source of groundwater for the surrounding population. Some problems associated with groundwater in Mount Merapi are high utilization compared to other volcanoes worldwide, changes in land use, pollution, and its lowering table. Therefore, this study aims to compare the hydrogeological characteristics and aquifer systems of the southern and southeastern parts of Merapi Volcano. The hydrogeological characteristics were obtained from geological mapping, surface and subsurface, as well as rock XRF tests. Meanwhile, the hydrogeochemical characterization was determined through chemical data using the Trilinear Piper, Kurlov, Fingerprint, Composition, and Harker Diagram methods. The results of the Trilinear Piper, Kurlov, Fingerprint, and Composition Diagram methods show that Mount Merapi has 3, 7, 4, and 2 types of patterns different from other volcanoes in the world. On the other hand, the Harker diagram has the same pattern of Mg-Ca and Mg-Na as several other volcanoes. In conclusion, the hydrostratigraphy in the southern part of the volcano, consists of aquifuge, aquiclude, and aquifer, while in the southeast, there are aquitards of volcanic sandstone and tuff.
