由陶片岩象分析結果來看新喀里多尼亞史前Lapita陶器的流通模式

Examining Possible Prehistoric Ceramic Transfers among Six New Caledonian Lapita Sites through Petrographic Analysis

在談到南島語族社群在西南太平洋中的傳播分佈方式時，Lapita陶器的製作方式、裝飾紋路、以及器型上的變化，一直是辨別族群及界定文化分類的重要利器。筆者們所執行之96無度國科會計畫「西南太平洋法屬新喀里多尼亞島群史前Lapita陶器之化學與礦物分析」即是企圖透過辨識新喀里多尼亞Lapita陶片中所含的化學與礦物成份，來找出島群內各遺址出土陶器之原料採集及生產製作的地點，並透過瞭解不同地區陶匠在製作Lapita陶器時所慣用的陶土摻和料組合類型，進而就地質背景與特性來探討此區域當時可能的陶器流通狀況，以及可能的社會經濟背景。本文總結了該計畫陶片岩象分析部份之研究成果，對於新喀里多尼亞Lapita文化時期之陶器流通狀況提出初步圖像，提供日後進行類似陶器岩象分析研究時的參考。

The diversity observed from aspects of manufacture techniques, decoration motifs, and morphology of Lapita pottery has long been employed by Pacific archaeologists to identify social group boundaries and classify different cultural periods, as they investigate the spread of the Austronesian-speaking populations into the vast Oceania. The ultimate research goal aims to discover possible raw material procurement areas and pottery-making workshops in New Caledonia through identifying tempers originated from specific geological zones and site-specific patterns of paste preparation, in both petrographic and chemical compositions, in order to discuss prehistoric ceramic transfers and the inferred social and economic meanings of Lapita pottery. This paper summarizes results of the petrographic studies of the research, and outlines a preliminary interpretation for the ceramic transfers occurred among these sites, in order to provide valuable information for future chemical compositional studies.
