Abstract :1 カジ屋敷遺跡は新潟県佐渡市西三川字カジ屋敷240番地他、せりば遺跡は西三川字せりば391番地他に所在する。遺跡は真野湾から内陸に約3㎞の小佐渡丘陵に位置し、立残山に隣接した標高約130mに所在する。西三川砂金山(笹川地区)の関連遺跡の中では北辺に位置する。 2 発掘調査は、一般県道静平西三川線改良工事に伴い佐渡市教育委員会が調査主体となり、平成18・19年度に実施された。 3 平成13~14年度にかけて、同事業に伴う別地点の発掘調査(第一次・第二次)が実施され、近世の砂金山における鍛冶小屋跡や水路跡、道路状遺構が検出されている。本調査区(A区・B区)はその北西側に隣接しており、北東側でカジ屋敷遺跡に接している。 4 今回の調査において、第一次・第二次調査で検出された石組水路の延長部分と考えられる水路跡が検出された。この水路跡は、史料調査の結果、真野地区豊田地内を水源とし、全長1.4㎞以上に及ぶことが判明した。さらに、嘉永3~4年(1851~1852)に設営された水路の一部で、採掘時に出たガラ石置き場の下部を掘り下げて砂金を回収するという、「取明普請」の最終形態にあたると想定される。 5 IIF1グリッドに位置する砂金採掘当時の鍛冶小屋跡の可能性がある石組遺構1基の実測調査を実施した。 6 せりば遺跡のD区でも立残山操業時のものと思われるガラ石の堆積が検出された。7 遺物は出土しなかった。 8 水路跡の検出やガラ石の堆積状況から、周知のカジ屋敷遺跡とせりば遺跡の範囲が、今回の調査区を含む部分にまで拡大することが明らかとなった。
1. Kajiyashiki remains and Seriba remains are both in Nishimikawa of Sado City, Niigata Prefecture ; the former is located at 240 Aza Kajiyashiki and the latter is at 391 Aza Seriba. They are set in the Kosado hills, approximate 3km inland from the Mano bay. The locations are approximate 130m up in the hills adjacent to Tatenokoriyama. They are on the northern rim of the region related to the remains of Nishimikawa alluvial gold deposits (in Sasagawa district). 2. Excavation activities were done by a research body led by Sado City Board of Education in 2006 and 2007 (fiscal years). The activities were associated with roadway improvement of the route Shizudaira-Nishimikawa. 3. The roadway improvement rendered other excavation activities in 2001 and 2002 (fiscal years) ; they were designated as the first and the second researches. These activities discovered remains of a blacksmith's workshop, waterways and roads for alluvial gold mines in the modern ages. The region (A and B sections) of this research adjoin the regions surveyed by the first and the second researches on the north west side and Kajiyashiki remains on the north east side. 4. This research discovered waterway remains that are considered to be an extension of the rock work waterway discovered by the first and the second researches. It was discovered based on the investigation of historical materials that the waterway remains had the water source in Toyota of Mano district and the overall length of 1.4km or longer. Furthermore, it was assumed that the remains were a part of the water way established in 1851 and 1852(the 3rd and 4th of Kaei) and the final form of “Toriake Fushin” which means “digging up a tunnel after it was blocked due to falling”in order to collect alluvial gold through a process digging down the bottom part of the storage site for crushed stones from mining. 5. A measurement survey of a set of rock work remains located in the IIF1 grid was done. It can be a blacksmith's workshop at the time of placer mining. 6. Remains of another rock work (accumulated crushed stones) that seems to have been used at the time of placer mining were also discovered in the section D adjacent to Seriba remains. 7. Not a relic was discovered. 8. Judging from the fact that remains of the waterway was discovered and the accumulated conditions of crushed stones, we can conclude that the scope of the known Kajiyashiki remains and Seriba remains should be extending over the region that including this research area.
