It's about Time? Testing the Dawson Ceramic Seriation Using Luminescence Dating, Southern Nasca Region, Peru

Dating the Dead: New Radiocarbon Dates from the Lower Ica Valley, South Coast Peru

“…This transition has yet to be properly defined both in terms of sociopolitical factors entailed and absolute chronology (see Cadwallader et al, in press). These dates contribute to the latter (and see also Vaughn et al 2014: Table 2).…”

“…Finally, the dates from individuals from Cemeteries 398 and 755 call into question the widely held notion that the end of the Middle Horizon on the south coast was marked by a complete absence of settlement, perhaps occasioned by some sort of environmentally induced crisis, until the dawn of the Late Intermediate Period some 3 centuries later (see inter alia Conlee 2010; Eitel and Mächtle 2009;Unkel et al 2012;Vaughn et al 2014). There are other large funerary contexts in the Samaca and Ullujaya Basins of the lower Ica Valley, including Cemeteries 752 and 208 whose related architecture and related Middle Horizon 4 material culture suggest that these were occupied continuously during this period, whose chronology and culture history remains poorly understood.…”

“…Moreover, ceramic sequences from Ica (Menzel 1964(Menzel , 1976Menzel et al 1964) underlie Rowe's (1967) widely used chronology for all Andean prehistory. Parts of those sequences are only now being tied to absolute radiocarbon dates on the south coast based on work in Nazca and Palpa (Unkel and Kromer 2009;Unkel et al 2012), while others still remain to be clarified or refined (and see Vaughn et al 2014). This study is the first to assess the ceramic chronology using 14 C-dated material from the Ica Valley itself.…”

Radiocarbon vs. Luminescence Dating of Archaeological Ceramics in the Southern Andes: A Review of Paired Dates, Bayesian Models, and a Pilot Study

“…Roddick, personal communication 2021). In the southern Nazca region in Peru, a large OSL study (Vaughn et al 2014) had a number of unexpected results compared to both ceramic seriation and Bayesian models of 14 C dates (Unkel et al 2012). Since so many factors affect archaeological dates, it is challenging to identify the cause of disagreement between methods, especially when dates do match in some cases.…”

“…In the southern Lake Titicaca Basin, TL dates from Qeya-style museum pieces in France underestimate the style's expected date range, based on Bayesian models of 14 C dates and stratigraphy(Marsh et al 2019; A. Roddick, personal communication 2021). In the southern Nazca region in Peru, a large OSL study(Vaughn et al 2014) had a number of unexpected results compared to both ceramic seriation and Bayesian models of 14 C dates(Unkel et al 2012).
