A number of the Bronze Age dwelling sites have been found and excavated in the Yoodoocheon, Onyangcheon and Baekseokdong basins. Two basins are located near Asan and Onyan in the Chungnam Province of South Korea. Baekseokdong is located in Cheonan, Chungnam. 207 dwelling sites are concentrated around the area of $1.3km^2$ in the Baekseokdong. 177 dwelling sites are sparse and distributed over the area of $1.3km^2$ in the Yongdoocheon and Onyangcheon basins. Most of the Bronze Age dwelling sites in those areas located on the hill. The hills have similar geomorphological environments except for slight differences in geological faces. This study analyzes geomorphological environments of the high-density residential zone of the Bronze Age in the Yoodoocheon and the Onyangcheon basins, and then compares them with the results in Baekseokdong. Study results show that high-density residential zone consists mainly of specific micro-landforms such as the Crest slope, the Crest flat and the Upper side slope, and southeast-facing aspect. A lot of Gentle slope lands were distributed in terms of terrain slope but it is far from specific geomorphological environments. This is not weighted in specific value. Our results show that the geomorphological characteristic derived from this study is major considerations to develop dwelling sites in the Bronze Age. This can be useful to discover the possible dwelling sites over other Chungnam hill regions.

The patternless potteries excavated from the Baekseokdong Gojaemigol site in Cheonan, was subdivided into talc and non-talc (including amphibole) type pottery. The potteries showed black, reddish brown and yellowish brown colors, but represent to difference with occurrences and internal texture of raw materials and temper minerals. The all potteries and paleosoils are commonly high content of temper minerals with poorly sorting and roundness of particles, and the paleosoils composed mainly of quartz, plagioclase, mica, chlorite and kaolinite. Between the talc and non-talc type potteries are very similar with magnetic susceptibility, absorption ratio and specific gravity. Geochemical behaviors of major, minor, compatible and incompatible elements in talc pottery are very similar with amphibole, non-talc pottery and paleosoils, and well correspondence with enrichment and deficiency patterns of each element, and the talc and amphibole potteries are highly enriched patterns of MgO concentration. In paleosoils of Gojaemigol site, talc and amphibole are not detected, therefore, making the pottery of the site estimate the possible to artificial additions of the temper minerals of talc and amphibole used interbedded talc layer within gneiss complex near the Baekseokdong area. Based on the phase relations, differential thermal and thermal gravimetric analyses, the potteries could be classified into two groups by firing temperature. The one group of talc temper pottery fired from 800 to $870^{\circ}C$ and the other group of amphibole and non-talc temper pottery revealed of 900 to $950^{\circ}C$.

We were to investigate the geomorphological environment of optimum location in the object of Bronze Age's dwelling site (hereinafter called dwelling site) of total of 205 units confirmed in the 'Cheonan Baekseokdong Relic Group' distributed in hill of the uppermost stream part in the watershed of Jangjae stream in Cheonan, Chungnam Province. To do this, we classified the hill of the object of investigation where dwelling sites were distributed as 8 units of slope micro-landforms and again by combining them with the grade of gradient of 5 units subdivided them into ultra-micro-landforms of total 40 units. On the foundation of this, in the viewpoints of 'gradients of each of micro-landforms' analyzed the 'number of dwelling sites' and 'dwelling site distribution density (measure: number of dwelling sites/1000m²) of 'Cheonan Baekseokdong Relic Group'. As the result, the optimum landform environment where the dwelling sites were located were found to be largely 5 units of ultra-micro-landforms - ① flat land of crest flat, ② gentle slope land of crest flat, ③ flat land of crest slope, ④ gentle slope land of crest slope and ⑤ semi-gentle slope land of crest slope. This analyzed material will be used from now on as basic material which can predict the distribution of dwelling sites of Bronze Age men who dwelled in the watershed of Jangjae stream.

Understanding the distribution and location characteristics of the settlements is preliminary study on discovering the formation and extinction process of the settlements used information of archeological excavation. So far, most researchers have been concerned about the location-environment of the dwelling. However, this study focuses on the understanding of the geomorphological environments in high-density residential zone. The study area is located in Cheonan, Chungnam, South Korea. It is called the Baekseokdong Heritage Group, which has 205 dwelling sites in the bronze age. This study is considered micro-landforms of hillslope, slope, and aspect from a view of geomorphological environments. In the study area, The high-density residential zones, the bronze ages dwelling sites are concentrated, consists mainly of slope land between undulated plain and semi -gentle of crest slope or crest flat, and south-facing aspect(southwest-south-southeast).

The purpose of this study were to interpret making characteristics and clay sources for Proto-Three Kingdoms period potteries which were excavated from Bakjimeure site in Tangjeong, Asan, Korea, on the basis of shape types. The pottery samples of the studied included deep bowl pottery, cylinder shaped pottery, duck shaped pottery and rounded based jar with short neck. And the last jar was dominant among them. This is supported in nearby Yongduri Jinter site, Galmaeri site and Baekseokdong site. They vary in terms of color of clay, absorption ratio and mineral classification. Based on the fact that their absorption ratio range was 4.50 to 25.19% and firing temperature range was 850 to $1,150^{\circ}C$, they were thought to be widely used. The equivalence of cylinder shaped pottery, duck shaped pottery and deep bowl pottery was high in terms of material characteristics and their firing temperature range was 850 to $950^{\circ}C$. However, the deep bowl pottery, compared to other pottery shapes, contained great amount of coarse grained quartz and feldspar, and was different from others in terms of function. For soil sample collected from relative plains (area 3) in the southernmost part of the site, their mineralogical and geochemical characteristics were the most similar to those of the potteries excavated from the Bakjimeure site and even most of the potteries collected from different sites.
