摘要

Architectural mortar from two ancestral Pueblo sites (Spruce Tree House and Nordenski?ld's Ruin 12) located in Mesa Verde National Park was investigated using visual, mineralogical, and geochemical techniques. Results indicate ancestral Pueblo people had a preference for mortars composed of sand and clay contents that produce a USDA textural class of sandy clay loam to clay loam. A temporal trajectory of soil selection is observed at Spruce Tree House, with mesa-top soils being preferred during the early period of occupation, but with soils below cliff dwellings preferred during later periods. Mortar geochemical composition is found to differ between cliff dwellings, and sometimes between households within a cliff dwelling, due to local soil differences and/or potential amendment additions. Results from Spruce Tree House indicate that contemporaneous households shared access to mortar sources. The prevalence and possible origins of gypsum found in mortar are discussed. Finally, this research examines the possibility that land tenure rights may have extended beyond those lands used exclusively for agricultural purposes.
