“…Access to geological resources was also essential to successful colonization. Potting communities often settled close to clay and temper deposits or had access to more distant sources during initial colonization (Heath et al, 2017). Moreover, after the Mt Witori (W-K2) eruption c. 1300 BC in New Guinea (Machida et al, 1996), modes of obsidian acquisition and exchange altered, following the appearance of Lapita communities.…”

Analysis of the spatial and temporal structure of global island colonization allows us to frame the extent of insular human cultural diversity, model the impact of common environmental factors cross-culturally, and understand the contribution of island maritime societies to big historical processes. No such analysis has, however, been undertaken since the 1980s. In this paper we review and update global patterns in island colonization, synthesizing data from all the major island groups and theaters and undertaking quantitative and qualitative analysis of these data. We demonstrate the continued relevance of certain biogeographic and environmental factors in structuring how humans colonized islands during the Holocene. Our analysis also suggests the importance of other factors, some previously anticipated—such as culturally ingrained seafaring traditions and technological enhancement of dispersal capacity—but some not, such as the relationship between demographic growth and connectivity, differing trophic limitations impinging on colonizing farmers versus hunter-gatherer-foragers, and the constraining effects of latitude. We also connect colonization with continental dynamics: both the horizontal transmission of farming lifestyles earlier in the Holocene, and subsequent centrifugal processes associated with early state formation later in the Holocene.

“…One of them consists of analyzing the clay matrix and the inclusions separately in an effort to avoid complications related to the pottery manufacturing process affecting the chemistry. The chemical composition of the clay matrix of pottery is used, often in combination with other techniques, to characterize assemblages, evaluate their variability, and occasionally compare them with natural clay samples (e.g., Anson, 1996; Cochrane & Neff, 2006; Eckert & James, 2011; Gaffney et al, 2015; Golitko, 2011; Heath, Summerhayes, & Hung, 2017; Hunt, 1989; Renson et al, 2010; Summerhayes, 2000; Sutton, Summerhayes, & Ford, 2019; Swete Kelly, 2008; Vilgalys & Summerhayes, 2016). The groupings identified by this approach and the resultant interpretations in terms of behaviors rely on the assumption that the chemical composition of clays collected from a “source” (whether it be a circumscribed geographic area, a zone with specific climatic and/or topographic conditions, or shared geological bedrock) will be homogenous enough to allow its characterization and its differentiation from other “sources” of raw material.…”

This article documents the significant horizontal (across the landscape) and vertical (across the stratigraphy) chemical variability of volcanic clays from Vanuatu, South Pacific. Data illustrate why the chemical composition of the clay matrix in pottery should be used very cautiously in characterization or provenance studies. The variability of natural clays on Efate, Erromango, and Malekula is so significant that the data set disproves the assumption that two pottery samples with clay matrices showing similar chemical composition necessarily originate from the same location, the same bedrock, the same region, or even from the same island. This study is also a reminder that the outcomes of chemical characterizations and provenance studies of pottery are directly dependent on the scale at which the investigation is undertaken. In light of the data, it is also clear that such studies should not be undertaken in other similar insular environments affected by regular volcanic activity along the Circum‐Pacific Belt without assessing the natural variability of the raw material. Without an adequate sampling of natural clay representative of the vertical and geographic variability, the results from the chemical analysis of clay matrices risk of leading to incorrect associations between pots and procurement areas.
