Abstract
We examined 2947 basalt and volcanic glass artifacts from 38 sites in leeward Kohala. Nondestructive energy-dispersive X-ray fluorescence provided initial geochemical characterizations. Wavelength-dispersive X-ray fluorescence (WDXRF) and thermal ionization mass spectrometry (TIMS) analyses were completed on samples from ambiguously sourced groups. No more than 13.9% of the probable and definite adze-related debitage originated in leeward Kohala. Notably absent are lithic materials from the nearby Pololū Adze Quarry in windward Kohala. Material from the more distant Mauna Kea Adze Quarry accounts for 41.6% of the adze debitage. Another 38.8% of the adze debitage matches with a tholeiitic source or sources long assumed to be Kīlauea Volcano in Kaʻū, but WDXRF and TIMS isotopic data do not support a Kīlauea source. Centralized adze production and distribution networks best explain adze distribution. Scoria abraders appear to have been regularly transported from the Kona district to leeward Kohala. Volcanic glass sources loosely align with distance-decay trends, but show greater reliance on Puʻuwaʻawaʻa material by 1650 CE.
期刊介绍:
Geoarchaeology is an interdisciplinary journal published six times per year (in January, March, May, July, September and November). It presents the results of original research at the methodological and theoretical interface between archaeology and the geosciences and includes within its scope: interdisciplinary work focusing on understanding archaeological sites, their environmental context, and particularly site formation processes and how the analysis of sedimentary records can enhance our understanding of human activity in Quaternary environments. Manuscripts should examine the interrelationship between archaeology and the various disciplines within Quaternary science and the Earth Sciences more generally, including, for example: geology, geography, geomorphology, pedology, climatology, oceanography, geochemistry, geochronology, and geophysics. We also welcome papers that deal with the biological record of past human activity through the analysis of faunal and botanical remains and palaeoecological reconstructions that shed light on past human-environment interactions. The journal also welcomes manuscripts concerning the examination and geological context of human fossil remains as well as papers that employ analytical techniques to advance understanding of the composition and origin or material culture such as, for example, ceramics, metals, lithics, building stones, plasters, and cements. Such composition and provenance studies should be strongly grounded in their geological context through, for example, the systematic analysis of potential source materials.
