Korea experienced a tragic loss of most of the Sungnyemun building in an arson attack in 2008. Few scientific records of the pigments originally used in the Korean national treasure exist, thus, the restoration of Sungnyemun was a serious failure. Because the Raman spectroscopic method has the advantage of analyzing the pigment phases in a simple, nondestructive, and noncontact way, it is becoming more important in scientific research on the colors present in cultural assets. In this study, Raman mapping measurements of the pigments in several “dancheong” - color decorations of the surfaces of the wood structure of Korean buildings - samples from Bongjeongsa Geukrakjeon and Sunglimsa Bogwangjeon are presented. The distribution of the pigments, which is difficult to observe with the naked eye, can be found in detail through a high-resolution Raman mapping image. A change of Raman spectrum due to the powderization of some pigments in the colored layer is also observed. The powderization of the pigments is considered to be due to weathering. Our Raman study will be helpful for the preservation and restoration of cultural heritage in general.

Dalsung Mine, located in Kyungsang puk-do, Korea, is well known as one of the typical breccia pipe filling hydrothermal W-Cu deposit. By homogenization temperature with fluid inclusions in quartz crystals (330 samples were dealt with) by heating stage microscope, two temperature ranges were figured out one is 154°~267℃(average 210℃), and the other is 283°~335℃(average 309℃). Regarding to mineral paragenesis, mineralization of the deposit were thought that former, mesothermal stage, W-Cu mineralization processed through out the ore body and later mineralization were limitted under -4level as katathermal solution with Cu minerals.
