仁愛鄉Tabuluk石器作坊遺址分析與研究

A Technological Analysis of the Lithic Workshop in Tabuluk, Ren’ai Township

二○一二年發現的Tabuluk遺址位於濁水溪上游，鄰近曲冰遺址。駁坎文化層中石片、石料、石坏等遺物層層壘疊，極是緊密。器物組合顯示成器甚少，但有高比例的石坏與石片，刃線少見使用消耗痕，種種訊息支持遺址的性質應為一處史前石器作坊。回顧過去考古分類的理論爭議，顯示取決分類標準的最佳策略係在維持分類體系的簡潔和明確，而這兩個原則在石器分類上尤其關鍵。本文立基在以技術屬性為軸線的階層分類體系，通過分析遺址文化層石製品的打片技術、石核形式與修整加工等模式，筆者認為以Tabuluk遺址為代表的獨特剝片傳統，是廣泛分布在濁水溪中上游和埔里盆地地區薄身石器的基石，其存在可能源遠流長，可以視為構成廣義大馬璘文化的本地要素之一。

The Tabuluk site was found in the upper Choshui River near the renowned Chuping (Qais) site in 2012. The roadcut reveals a dense cultural deposit of knapped lithic embedded in a stratified formation. The lithic types demonstrate low proportions of formal tools but higher amounts of preforms and flakes. Taken together with the fact that edge wear is rarely found, it is suggested that this place was probably a prehistoric lithic workshop. A brief review of lithic classification shows that the best strategy is to keep one’s system concise and explicit. Based on the systematic classification focusing on knapping technology, my analysis of core types, striking methods and retouch patterns suggests that the Tabuluk assemblage represents a distinctive knapping tradition that is the predecessor to various so-called thin-section stone tools widely used throughout the mid-to-upper Choshui River valley and Puli basin. It is further argued that this characteristic knapping tradition may have been an essential local element in the configuration of Tamalin culture.
