Ethnohistoric accounts of late precontact Hawaiian archaic states emphasize the independence of chiefly controlled territories (ahupua'a) based on an agricultural, staple economy. However, elite control of unevenly distributed resources, such as high-quality volcanic rock for adze production, may have provided an alternative source of economic power. To test this hypothesis we used nondestructive energy-dispersive X-ray fluorescence (ED-XRF) analysis of 328 lithic artifacts from 36 archaeological features in the Kahikinui district, Maui Island, to geochemically characterize the source groups. This process was followed by a limited sampling using destructive wavelength-dispersive X-ray fluorescence (WD-XRF) analysis to more precisely characterize certain nonlocal source groups. Seventeen geochemical groups were defined, eight of which represent extra-Maui Island sources. Although the majority of stone tools were derived from Maui Island sources (71%), a significant quantity (27%) of tools derived from extraisland sources, including the large Mauna Kea quarry on Hawai'i Island as well as quarries on O'ahu, Moloka'i, and Lāna'i islands. Importantly, tools quarried from extralocal sources are found in the highest frequency in elite residential features and in ritual contexts. These results suggest a significant role for a wealth economy based on the control and distribution of nonagricultural goods and resources during the rise of the Hawaiian archaic states.adze quarrying | geochemical sourcing | Polynesian archaeology T he varied sources of power used by elites during the processes of sociopolitical evolution are of great interest to historical anthropologists. Over the course of two centuries preceding initial contact with Europeans in A.D. 1778-1779, Hawaiian sociopolitical organization was transformed from a system of complex chiefdoms to one of emergent archaic states (1). Among the processes thought to have driven this transformation were population growth, intensification of agricultural production, materialization of ideology and ritual, and elite competition associated with territorial conquest (1-5). Hawaiian sociopolitical evolution has been characterized as a classic case of a "staple economy" in which elite control of agricultural surplus was key (3). Ethnohistoric descriptions of Hawaiian economic organization emphasize the independence of chiefly controlled territories called ahupua'a, which are often described as largely autonomous and self-sufficient (3, 6-8). Nonetheless, certain key resources were concentrated or available only in particular locales; control over their distribution and use is likely to have been an important source of economic power. Arguably, such control would have involved a form of "wealth economy" in which Hawaiian elites (ali'i) exercised control over economically important resources or materials that were differentially distributed over island landscapes (1).Most of the resources that would have underwritten a wealth economy consisted of perishable materials (e.g., salt, f...
