Implications for Migration and Social Connections in South-Central New Mexico Through Chemical Characterization of Carbon-Painted Ceramics and Obsidian

Magdalena Black-on-white ceramics from two sites (Gallinas Springs and Pinnacle Ruin) in west-central and southwestern New Mexico have been interpreted as evidence of a migration of Northern Pueblo groups from the Four Corners region into southwestern New Mexico during the thirteenth century. They also appear to be linked to sites with similar carbon-painted ceramics on the Rio Puerco of the east and beyond. An additional site (Roadmap Village) reveals import of Magdalena Black-on-white ceramics produced at Gallinas Springs as well as possible local production. Limited quantities of carbon paint ceramics have been found on El Paso Phase sites in south-central New Mexico that have previously been attributed to contemporaneous carbon-painted pottery produced at communities in the Galisteo Basin and the upper Rio Grande. Recent compositional analysis of carbon-painted ceramics from the Gallinas Springs, Pinnacle, and Roadmap sites has identified characteristic chemical signatures that suggest local production of carbon paint ceramics at all three sites and distribution of carbon paint ceramics from Gallinas Springs to Pinnacle and Roadmap in the eastern Black Range of southwestern New Mexico. Analysis of carbon paint ceramics from Madera Quemada, an El Paso Phase site in the Tularosa Basin indicates that the carbon paint wares found in El Paso Phase sites were acquired through trade connections from the Black Range rather than from more northern sources. The overall Magdalena Black-on-white production patterns are contrasted with the obsidian procurement data from the same sites to reveal a complex and divergent pattern.
