Principle and Application of ‘Image-mapping’ in-situ U-Pb Carbonate Age-dating

We introduce a new ‘image-mapping’ in-situ U-Pb dating method using LA-ICP-MS, proposed by Drost et al. (2018), and show the characteristics and usability of this method through several examples of absolute age results determined by first applying it to samples from the Joseon Supergroup of the Early Paleozoic Era in Korea. Unlike the previous in-situ spot analysis, this in-situ U-Pb dating method for carbonate minerals can determine the absolute age with high reliability by applying the 'image-mapping' method of micro-sized domains based on micro-textural observation, as well as determine...

Identification of Sorption Characteristics of Cesium for the Improved Coal Mine Drainage Treated Sludge (CMDS) by the Addition of Na and S

Most of previous cesium (Cs) sorbents have limitations on the treatment in the large-scale water system having low Cs concentration and high ion strength. In this study, the new Cs sorbent that is eco-friendly and has a high Cs removal efficiency was developed by improving the coal mine drainage treated sludge (hereafter ‘CMDS’) with the addition of Na and S. The sludge produced through the treatment process for the mine drainage originating from the abandoned coal mine was used as the primary material for developing the new Cs sorbent because of its high Ca and Fe contents. The CMDS was i...

Study of Spatiotemporal Variations and Origin of Nitrogen Content in Gyeongan Stream

This study aimed to understand the spatiotemporal variations in nitrogen content in the Gyeongan stream along the main stream and at the discharge points of the sub-basins, and to identify the origin of the nitrogen. Field surveys and laboratory analyses, including chemical compositions and isotope ratios of nitrate and boron, were performed from November 2021 to November 2022. Based on the flow duration curve (FDC) derived for the Gyeongan stream, the dry season (mid-December 2021 to mid-June 2022) and wet season (mid-June to early November 2022) were established.In the dry season, most sampl...

Study on Evaluation of Critical Minerals for the Development of Korea's Materials-parts Industry

Through COVID-19, the importance of supply chain management of raw material minerals has been maximized. In particular, supply chain management is important for rare metals, which are difficult to manage demand and supply, in order to secure raw materials for the parts and materials industry that Korea is actively promoting. In this study, a system was established and evaluated to select Critical minerals that need to respond to Korea's industrial structure and global risks by quantifying tangible and intangible risk factors. Global Supply Concentration, Supplying country risk, Policy Social E...

Review for Mechanisms of Gas Generation and Properties of Gas Migration in SNF (Spent Nuclear Fuel) Repository Site

Gases originated from the final SNF (spent nuclear fuel) disposal site are very mobile in the barrier and they may also affect the migration of radioactive nuclides generated from the SNF. Mechanisms of gas-nuclide migration in the multi-barrier and their influences on the safety of the disposal site should be understood before the construction of the final SNF disposal site. However, researches related to gas-nuclide coupled movement in the multi-barrier medium have been very little both at home and abroad.In this study, properties of gas generation and migration in the SNF disposal environme...

Distribution of Freshwater Organisms in the Pyeonggang Stream and Application Effects of Hydrothermal Energy on Variations in Water Temperature by Return Flow in a Stream Ecosystem

This study aimed to predict the effects of water ecology on the supply of hydrothermal energy to model a housing complex in Eco Delta Smart Village in Busan. Based on the results, engineering measures were recommended to minimize problems due to possible temperature variations on the supply of hydrothermal energy from the river. The current distribution of fish, benthic macroinvertebrates, and phytoplankton in the Pyeonggang Stream was monitored to determine their effects on water ecology.In the research area, five species and three families of fish were observed. The dominant species was Lepo...

Investigation of Source Area and Material Characteristics of the Stone Properties from Stone-lined Tombs in Cheongyang Rokpyeong-ri Site, Korea

In the stone-lined tombs from Cheongyang Rokpyeong-ri site, several stone-lined tombs corresponding to the Three Kingdoms Period, Unified Silla Period and Goryeo Dynasty were excavated. In this study, the stone properties of petrological, mineralogical and geochemical characteristics from 15 stone-lined tombs were analyzed, the rock species and occupation rate were reviewed, also the provenance area was interpreted. There are five types of rocks used as members of the tombs, including black sandstone, greywacke, slate, conglomerate and gneiss. As a result of magnetic susceptibilities, the rock...
