Abstract
In case of Korea, limestone is very useful in various industries. These limestones are mainly produced in Gangwon-do. The study area, which is located in Okgye-myeon, Gangneung-si, Gangwon-do, is Okcheon metamorphic belt where abundant limestone, dolomite stone, and high-grade limestone are produced. The purpose of this study is to distinguish between calcite and dolomite among the limestone which is one of the representative carbonate rocks using the spectral characteristics. For this study,spectral characteristics were measured in the field and laboratory using FieldSpec® 3 spectrometer equipment from Analytical Spectral Device Inc. (ASD). In the field, the reflectance was measured below 50 cm from rock surface, and in the laboratory, the reflectance was measured in the rock surface, the polished surface, and the rock powder. As a result, absorption wavelengths of calcite and dolomite were significantly different around 2,330 nm. In particular, the absorption wavelength band position of dolomite appeared before 2,330 nm wavelength compared to calcite. The study could be used as a basis data for analysis of high-grade calcite limestone.
