Discussion on the origin of the Sangdong tungsten mine based on its mineral assemblage

This report is written for presenting a principal theme of study about the origin of Sangdong ore deposit in details, being an aid to find new ore bodies, on the basis of mineralogical charactor and geological feature. Main vein in Sandgong mine has Characteristic zonal distribution and localization of minerals. 3 kinds of minerals, that are quartz, hornblende, diopside, form systematically their each rich zones. Other minerals like Plagioclase, native bismuth, sphene, molybdenite and wolframite are developed locally. According to the zonal distribution and localization of the minerals, the authors presume that mineralizing agents which changed interbedded limestones into ore bodies act and come up from non-exposed igneous body in the direction perpendicular to the platy main vein. That non-exposed igneous body, presumed, might be extended from the exposed igneous bodies in the southern part of Sangdong mine.
