[SEM20-08] Paleomagnetism and rock magnetism of Nishiyama old kilns of Shino old kiln complex
Keywords:Paleomagnetism, Rock magnetism, Archaeology
Shino old kiln complex is located in the west of Kyoto old capital and includes over 100 old kilns. They were operated mainly in the 8-11th century, which follows the main period of the Sue-mura and other Sue-were complexes. Paleomagnetic results from Shino kilns are expected to fill the gap between Sue-were period and the new-generation potteries after the 11th century.
Here we report the paleomagnetic results from Nishiyama 1-1 and 1-2 old kilns in the Shino group. The paleodirections from the two kilns show a difference, which indicates the gap of the operated dates. Acctually the archaeological investigations of the pottery morphology and stratigraphy of the ash field also show the same result that the 1-2 kiln is half-of-century newer than the 1-1 kiln.
The age of the kilns estimated by matching of the direction onto the regacy geomagnetic secular variation curve (Hirooka, 1977) is different from the archaoelogical age. However, in case of using our new secular variation model, there is a consistency between paleomagnetic and archaeological ages.
