Most of the fluorite ore deposits in Kumsan district occur in the Chinsan area. Specifically, these are the Okgye, Hyongyang, Ilyang, Manak fluorite ore deposits. Field survey and fluid inclusion study were undertaken to illustrate the characters and origin of the fluorite ore deposits in Chinsan area. The results of this study are as follows; Gology of the Chinsan area is composed of Majonri Formation and Changri Fomation which belong to Okchon Group and Jurassic biotite granite and Cretaceous pink feldspar granite and quartz porphyry. The wall rock of fluorite ore deposits in Chinsan area are chiefly limestone in Majonri Formation and partly limestone in Changri Formation. The relevent igneous rocks of the fluorite ore deposits are chiefly quartz porphyry, but some are biotite granite or pinkfeldspar granite. The fluorite ore deposits in this area are chiefly contact metasomatic deposits which were formed while limestones were intruded by quartz porphyry, biotite granite and pink feldspar granite. The filling degrees of fluid inclusions in fluorite ranges 84∼95% in Okgye, 85∼95% in Hyongyang, 85∼91% in Ilyang, 92∼96% in Manak ore deposits. The salinity (NaCl equivalent weight percent) ranges 0.1∼1.5wt.% in Hyongyang. 0.3∼2.8wt.% in Ilyang. 0∼1.5wt.% in Manak ore deposits. The homogenization temperature of fluorite ore deposits in Chinsan area ranges 97.6∼191.6C in Okgye, 99∼168.4C in Hyongyang. 100∼214C in Ilyang, 122∼248.6C in Okgye, 99∼168.4C in Hyongyang, 100∼214C in Ilyang, 122∼248.6C in Manak ore deposits. These data indicate that Chinsan Fluorite ore deposits belong to the epithemal or mesothemal deposits same as the other fluorite ore deposits in Korea.
