Abstract
Environmental reconstruction at the site level is crucial for gaining a nuanced understanding of human-environment interactions in prehistoric period. The Haimenkou wetland archaeological site, located on the Yunnan Plateau in Southwest China, offers an opportunity to investigate how local environmental conditions have changed since the late Pleistocene and how humans adapted to and modified these landscapes over time. This study employs a multi-proxy approach to reconstruct the sedimentary history and physical environment surrounding the site. Our results indicate that before human occupation, Neotectonic activity and climatic fluctuations played the most significant roles in shaping the land surface. The Jianchuan Basin, where Haimenkou is situated, underwent considerable geomorphological changes driven by these natural forces, including shifting lake levels and erosional processes. However, once human settlement began, anthropogenic activities—such as forest clearance, agriculture, and the expansion of settlements—became the dominant forces altering the environment. The findings also have broader implications for understanding the “Missing Millennia”—a term used to describe the scarcity of archaeological sites from the Mid-Holocene across Southwest China and mainland Southeast Asia. Our research suggests that active erosion, sediment transport, and redeposition during this period likely played a significant role in the poor preservation of archaeological remains.
期刊介绍:
Geoarchaeology is an interdisciplinary journal published six times per year (in January, March, May, July, September and November). It presents the results of original research at the methodological and theoretical interface between archaeology and the geosciences and includes within its scope: interdisciplinary work focusing on understanding archaeological sites, their environmental context, and particularly site formation processes and how the analysis of sedimentary records can enhance our understanding of human activity in Quaternary environments. Manuscripts should examine the interrelationship between archaeology and the various disciplines within Quaternary science and the Earth Sciences more generally, including, for example: geology, geography, geomorphology, pedology, climatology, oceanography, geochemistry, geochronology, and geophysics. We also welcome papers that deal with the biological record of past human activity through the analysis of faunal and botanical remains and palaeoecological reconstructions that shed light on past human-environment interactions. The journal also welcomes manuscripts concerning the examination and geological context of human fossil remains as well as papers that employ analytical techniques to advance understanding of the composition and origin or material culture such as, for example, ceramics, metals, lithics, building stones, plasters, and cements. Such composition and provenance studies should be strongly grounded in their geological context through, for example, the systematic analysis of potential source materials.
