Revising 11 historical topography of Jecheon city we could notice that this territory was traditionally producing high quality medicinal plants. This view is supported as it was tributed to the King. Production of medicinal plants continue these days, Jecheon being one of the largest production of medicinal plants in Korea. Abundant production of diverse medicinal plants of high quality seems to be linked with the soil, climate and environmental characteristics unique of Jecheon. Therefore we propose to develop new type of herbal medicin drugs like Gobang(膏方) which could distinguish from other places. Gobang matchs well to the requirement of current days being convenient to carry and of good taste. Also is appropriate to treat chronic diseases. Its primordial abundant herbal medicines of high quality for the development of Gobang where Jecheon can provide.

Detrital zircon U-Pb dating was performed to determine the depositional age and provenance of sediments in the Cretaceous Muju Basin in Muju-gun, Jeollabuk-do. Six samples were collected from the Seolcheon Tuff (SCT), Bangyiri Formation (BYR), Gobang Member of the Gilwangri Formation (GWR-G), Seochang Member of the Gilwangri Formation (GWR-S), Bukchang Member of the Gilwangri Formation (GWR-B), and Jeogsangsan Formation (JSS). Based on the dating results, the sedimentary strata of the Muju Basin were deposited for approximately 105.6-90.4 Ma corresponding to the Albian to Turonian. The youngest single zircon ages of about 94.4 Ma and 89.6 Ma were confirmed in the samples from the Bangyiri Formation and the Gobang Member of the Gilwangri Formation, respectively, distributed in the western part of the Muju Basin. The relative and numerical ages previously estimated based on the lithostratigraphic correlation of the Gilwangri conglomerate need to be revisited in further research. The results also suggest that most of the sediments filling the Muju Basin were supplied from a limited area adjacent to the basin.

This report is the result of the basic geologic investigation for the purpose of preparing the long-term development program of the U-jeon Consolidated Coal kline. The Consolidated Coal Mine is located at Gujeol-ri, Wangsan-myeon, Myeongju-gun, and Yucheon-ri, Bug-myeon, Jeongseon-gun, Gan-gweon Province (128$^{\circ}$ 43′10.4"-128$^{\circ}$ 46′10. 4"of east long-ititude, 37$^{\circ}$ 30′-37$^{\circ}$ 33′ of north latitude). This region, the western part of Taebaek mountain range, shows a ragged mountinous feature. Formations of the Pyeongan System of Paleozoic Era are distribu ted in the region with the surrounding Great Limestone Series of Joseon System which covers the south-eastern part of the region. The Pyeongan System is divided into four formations, namely, the Hongjeom, the Sadong, the Gobang and the Hongam, in ascending order. The sadong Formation intercalates several coal beds, and two coal beds out of them are minable. The coal beds are variable in thickness, having the repeated swelled or poket and the pinched parts, which suggest all intense disturbance caused by folding. The heat value of the coal is 5, 500cal. on the average. The total amount of coal reserves of the U-jeon consolidated Coal Mine is estimated at about thirty million metric tons.
