The importance of graphite is increasing with the global shift toward carbon neutrality and clean energy transitions. As a critical mineral for battery anodes, graphite demand is projected to grow fourfold by 2030 compared to 2023 levels, with overall demand doubling during the same period. However, graphite is classified as a high-risk mineral due...

Electrochemical reactions at the interface between groundwater and sulphides are remarkable. Sulphides in mineralised zones are relatively abundant compared to hydrothermal alteration zones and host rocks. Complex resistivity is a geophysical tool for visualising difference between various subsurface electrochemical reactions. The epithermal Au–Ag...

The South Korean government culled and buried numerous pigs to contain the 2011 outbreak of foot-and-mouth disease. Pollutants were detected in groundwater samples collected from an observation well near animal carcass waste (ACW) facilities used to dispose of some of the culled animals. Pollutants appeared to be leachate seeping through damaged sh...

As the potential locations of undiscovered ore deposits become deeper, a technique for predicting promising areas in the subsurface media has become necessary. Geoscience data on a wide range of underground media can be obtained through geophysical field exploration, but integration and interpretation of multi-geophysical data are difficult because...

Precambrian igneous rocks (851–873 Ma) occur in Pocheon City, Korea. These rocks—crystallized during magmatic differentiation—formed vanadiferous titanomagnetite (VTM) deposit. Vanadium is a crucial element in vanadium redox flow batteries that are most appropriate for large-scale energy storage systems. We investigated the VTM deposit to evaluate...

We present our aeromagnetic survey results from an investigation of the iron ore mineral distribution in Pocheon, Korea, in the west-central area of the Korean Peninsula. A manned aeromagnetic system using a helicopter for regional exploration and an unmanned aeromagnetic system using a multicopter for high-resolution exploration were used for the...

The Yeoncheon titanomagnetite deposit formed by Precambrian magma differentiation is located in Gyeonggi-do, South Korea. Our team conducted an airborne magnetic survey for multiscale mineral exploration and then selected a promising survey area. An electrical resistivity survey was carried out in the potential area to image subsurface structure. B...

Early detection of piping in earthen dams is critical in preventing substantial damage due to dam failure. Although it is significantly difficult to directly identify piping caused by subsurface seepage and soil erosion, these subsurface phenomena are indirectly detectable from electrical property changes using the electrical resistivity tomography...

The Geodo skarn deposit is located in the Taebaeksan Basin, central eastern Korean Peninsula. The geology of the deposit consists of Cambrian to Ordovician calcareous sedimentary rocks and the Cretaceous Eopyeong granitoids. The skarns at Geodo occur around the Eopyeong granitoids, which consist, from early to late, of magnetite-bearing equigranula...

It has long been that we may be able to differentiate between different lithology units from the dependence of induced polarization (IP) signal on the mineral composition and pore space distributions. The commonly used, knowledge-driven approach based on equivalent circuit analyses, however, tends to be challenged with severe ambiguities. To overco...

In successive alkalinity-producing systems (SAPS), the limestone tends to get coated with precipitates, reducing the permeability of the SAPS, the mine water treatment efficiency, and the service life of the SAPS. Further study of the precipitates are required to improve the design of flushing systems. In this study, the growth characteristics, par...

The development of more advanced geophysical exploration techniques is necessary because the orebodies as yet discovered are increasingly changing in characteristics from shallow/high-grade to deep/low-grade. In this work, laboratory measurement of physical properties of rock samples and a field survey and interpretation of spectral induced polariz...

The determination of mineralization boundaries during mineral exploration for undiscovered low-sulfidation epithermal Au-Ag deposits is a significant challenge because of the extensive survey areas required. Induced polarization (IP) imaging is an effective geophysical technique for the detection of sulfides or clay. Thus, this method is considered...

Recently, the use of electrical prospecting with high spatial density of electrodes has increased and is being applied to underground investigations for mineral exploration and other civil engineering purposes. In order to characterize rock mass using the resistivity distribution of ground, which is obtained from these investigations, it is importa...

Spectral-induced polarization (SIP) using the electrochemical reaction at the interface between mineral particle and groundwater is a powerful tool for the exploration of minerals. However, SIP responses of rocks have not been fully characterized because it is influenced by various petrological properties. In this study, the relationship between SI...

The Wondong Fe-Pb-Zn polymetallic skarn deposit is located in the Taebaeksan Basin, South Korea. This deposit is associated with the Paleocene quartz porphyry and characterized by abundant exoskarn and subordinate endoskarn. A general zonation pattern is developed comprising a proximal reddish-brown garnet-rich zone, a distal greenish garnet +/- py...

Equivalent circuit analysis is a valuable tool for the interpretation of spectral induced polarization (SIP) data. It is not easy to select an appropriate circuit model for analyzing SIP data of ores because the ores are heterogeneous and the circuit model has ambiguity. In view of this, a new circuit model, which was based on the electrochemical t...

Spectral-induced polarization (SIP), which measures the responses to alternative current of multi-frequencies below 1 kHz, is an excellent technique for exploring the economic minerals in the ore deposits. However, the studies on the SIP characteristics of rocks from ore deposits have rarely been conducted due to the decline of mining activities. F...

Gagok Mine, which is skarn deposits, includes sulfide minerals such as sphalerite, galena, chalcopyrite, and pyrrhotite. To explore these minerals, spectral induced polarization (SIP) is relatively effective compared to other geophysical exploration methods because there is a strong IP effect caused by electrode polarization. In the SIP, the charge...

Spectral induced polarization (SIP) is a useful technique, which uses electrochemical properties, for exploration of metallic sulfide minerals. Equivalent circuit analysis is commonly conducted to calculate IP parameters from SIP data. An equivalent circuit model, which indicates the SIP response of rock, has a non-uniqueness problem. For this reas...

Geophysical exploration is widely used to develop strategic mineral resources in the world because of its efficient method in detecting mineralized zones in the metallic ore deposit. It is important to understand the physical properties of the stratum so that geophysical data can be more accurately interpreted. This paper is to comprehend physical...
