Pebble-bearing clastic carbonate rock which has been found in and around the Jeongseon and Okgye through the field survey was studied in petrological and mineralogical characteristics. We define the clastic carbonate rocks as 'Dolomite-pebble bearing fine sand-sized dolostone, or grainstone', which are characterized by the existence of dolomite single grains and Mg-phengite, and by the subsequent formation of secondary calcite cements. These attributes correspond well with those of the typical Haengmae Formation from Haengmae-dong, Mitan-myeon, Jeongseon-gun, thus the carbonate rocks in the Jeongseon and Okgye areas must belong to the Haengmae Formation. The result suggests that the Haengmae Formation is an independent unit among the Paleozoic lithostratigraphic units in Taebaek basin and lies in the upper part of Jeongseon and Sukbyungsan Formations under the Hongjeom Formation of Pyeongan Supergroup.

Mt. Jabyeong(872.5m), limestone region in the Taebaek mountains, located in 37° 32'N, 129° 25'E and in Sangye-ri, Okgye-myeon, Gangreung-si and Samok-ri, Imgye-myeon, Jeongseon-gun, Gangwon-do. The purposes of this study were to investigate the floristic composition from 1997 to 1998 in Mt. Jabyeong and report the distribution of Korean endemic plants, rare and vulnerable plants, calcicoles and calci fuges, The vascular plants in this area were composed of 93 families, 313 genera, 3 subspecies, 57 varieties, 13 forms, 495 species, totaling 568 taxa. Among the vascular plants, 21 taxa were Korean endemic plants and 7 taxa were rare and vulnerable plants. Calcicole and calcifuge plants in this study area were composed of 21 families, 30 genera, 36 species and 14 families, 15 genera, 17 species. The soil pH values of study site in Mt. chabyoung were ranging 7.4∼8, which showed that this site was a mostly limestone area with alkaline soil. And soil depth was formed to a relative thin layer, mostly 2～4cm thickness. This site showed high content of moisture and organic matter which were ranging 40-45% and 15-25%, respectively.
