한국 융기문토기의 연대 재고

Abstract

Raised-design pottery is a type of pottery representative of the early Neolithic period in Korea. Particularly in the southern part of the Korean peninsula, pottery was divided into four types and created a long tradition of pottery lasting about 1,000 years. It is a well-known fact among Neolithic researchers in both countries, Korea and Japan that this type of pottery has been found in many coastal sites in the northwestern Kyushu region in Japan. In particular, the Koshitaka Site on Tsushima Island, Nagasaki Prefecture, is famous for the discovery of many pottery of the first half of the comb-patterned pottery, which is common to the southern part of the Korean peninsula, including Raised-design pottery. We, the Department of Archaeology, Kumamoto University, have conducted excavations at this site four times since 2015, jointly with the Tsushima Board of Education, and have obtained various information about the characteristics of the site that were not well understood until now. This paper examines the revision of the age of Raised-design pottery, one of the results of excavations that could not be fully explained due to the limited number of characters in the previous report, by adding new materials. In analyzing the dating values, we studied the types of charcoal, seeds, and charcoal attached to pottery, examined the presence or absence of a marine reservoir effect by the C value, and performed calibration using IntCal 20 and Marine 20. As a result, the age values indicated by the plant samples showed the most reliable age values, and in the case of Korean Neolithic sites located on the coast, it was reconfirmed that the influence of the marine reservoir effect is large. Although Raised-design pottery in southern Korea and Tsushima follow almost the same pattern changes, we concluded that the existing chronology of Raised-design pottery in Korea is about 400 years older than the new chronology based on reliable age values and that a revision is necessary.
