사적(史蹟)68호(號) 고려청자도요지(高麗靑瓷陶窯址)의 고고지자기(考古地磁氣)
김광호,배영부,Kim, Kwang Ho,Bea, Young Boo 대한자원환경지질학회 1983 자원환경지질 Vol.16 No.4
Recently, excavation of ancient pottery kiln of Koryo celadon of the Koryo dynasty have been continued since 1979 in Hang-dong, Daegu-myun, Gangjin-gun, Jeonnam Province, south-western part of Korea. The authers carried out an archeomagnetic study using the baked earth of the floors of the kiln, togimi and fabrics of rocks which were placed firmly on the floors of the kiln. These specimens were measured using the astatic magnetometer. The results of measurements are: declination, $0.3^{\circ}W$; inclination, $52.9^{\circ}C$. Referring to the secular change curves drawn from the studies of the south-western Japan, the last period when the pottery kiln was fired finally is estimated to be around A.D. 1170. Many potsherds of Koryo celadon were excavated around the kiln. According to the shape of these potsherds, the age of the pottery kiln is estimated to be 10-12 C, which is consisted with this study.

동보(東寶) 중석(重石)-모리브덴 광상(鑛床)의 광물공생(鑛物共生)과 유체포유물(流體包有物)
박희인,문상호,배영부,Park, Hee-In,Moon, Sang Ho,Bea, Young Boo 대한자원환경지질학회 1985 자원환경지질 Vol.18 No.4
The Dongbo tungsten-molybdenum deposits are fissure-filling veins emplaced in granites of late Cretaceous age. Integrated field, mineralogic and fluid inclusion studies were undertaken to illuminate the characters and origin of the ore deposits. Mineral paragenesis is complicated by repeated fracturing, but four distinct depositional stages can be recognized; (I) tungsten-molybdenum minerals-quartz-chlorite stage, (II) iron-oxide and sulfides-quartz stage, (III) iron -oxide-base metal sulfides-sulfosalts-quartz-carbonates stage, (IV) barren rhodochrosite-zeolite stage. Fluid inclusion studies were carried out for stage I quartz and stage III quartz, sphalerite and calcite. Fluid inclusion studies reveals highly systematic trends of homogenization temperature and salinity throughout the mineralization. Ore fluids during stage I were complex, NaCl rich brine and salinity reached values as high as 34.4 weight percent equivalent NaCl, but the later ore fluids were more dilute and reached to 9.7 weight percent equivalent NaCl during stage III. Intermittent boiling of ore fluid during stage I is indicated by the fluid inclusions in stage I quartz. Depositional temperatures and pressures during stage I range from $520^{\circ}C$ to $265^{\circ}C$and from 600 to 400 bars. Homogenization temperatures of the stage III quartz, sphalerite and calcite range from $305^{\circ}C$ to $190^{\circ}C$. Fluid inclusion data from the Dongbo mine are nearly similar to those from other hydrothermal tungsten deposits in the Kyeongsang basin. Depositional temperature and salinity of ore fluids during precipitation of tungsten-molybdenum minerals in Dongbo mine were much higher, but $CO_2$ contents were much lower than those from hydrothermal tungsten-molybdenum deposits of late Cretaceous plutonic association in central parts of Korean peninsula.
