This study presents the first area-wide geoarchaeological reconstruction of the Holocene landscape and settlement history in eastern Bubastis. Using coring, electrical resistivity tomography, and direct current resistivity soundings, we identified several Pleistocene sand mounds (‘Geziras’) that provided flood-safe locations for key buildings and housing. Surrounding low-lying floodplain areas, regularly inundated by the Nile, were likely used for agriculture. The thickest anthropogenic deposits—up to 9.5 m—were documented in settlement area S1, reflecting dense occupation during the Ptolemaic and Roman periods. In contrast, area S2 was sparsely settled and likely used for farming, benefiting from nutrient-rich floodplain sediments deposited by a nearby Nile branch.

This event was significant for two reasons. First, it was and remains the only successful attempt to orbit and eventually land on a comet's surface, opening up myriad possibilities for the scientific study of surface processes on this type of celestial body. Second, the landing of Philae, coupled with the eventual crash of the Rosetta spacecraft, officially initiated the formation of an archaeological record on 67P/CG. Here, we provide a review of comet surface and archaeological site formation processes and introduce the Rosetta mission as a case study for the application of planetary geoarchaeology. Our results suggest that although dynamic, the cometary environment is capable of preserving archaeological material within narrow windows of time. Specifically, this “preservation window” is dependent on several key geological factors, including local sublimation activity, fracturing, mass-wasting events, outbursts, large-scale splitting of parts of the nucleus, sedimentary processes, pit formation, meteoritic impacts, and rotational instability. As we continue to expand our material footprint across the solar system, we believe planetary geoarchaeology will offer crucial insights into the preservation of space heritage and the growing archaeological record of space exploration.</p></div>","PeriodicalId":55117,"journal":{"name":"Geoarchaeology-An International Journal","volume":"40 4","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144634972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

Since the 1950s, it has been explored using traditional archaeological methods and, more recently, non-destructive techniques like aerial prospection and geophysics. The archaeo-geophysical survey using magnetometry revealed more frequent fragmented linear magnetic anomalies and decreased magnetic intensities, indicating some differences in the sunken archaeological features. We hypothesised that these differences result from soil erosion. To test this, we conducted field surveys at well-documented archaeological sites, comparing changes in the depths of sunken features. Additionally, erosion modelling was used to reveal whether the field survey results align with the present modelled potential soil erosion. Findings indicate that this unique settlement area is threatened by water and tillage soil erosion to such an extent that some of the sunken features are being destroyed. The rate of soil erosion estimated by the field survey is between 0.6 and 18 mm.year<sup>−1</sup>; the modelled total soil erosion for the resurveyed features was up to 3.6 mm.year<sup>−1</sup> (50.7 t ha<sup>−1</sup> year<sup>−1</sup>). Modelling also suggested even higher erosion on a slope where a smaller rondel was detected by a geophysical survey in 2019 but remains unexcavated. The results highlight the urgent need for conservation efforts to protect this unique archaeological settlement site featuring three rondels on the same land from further degradation.

Two tributaries, from Caparon and Eygalières, converged in a basin before an arcade bridge, from which a single channel continued to Arles. Originally, the Caparon branch alone supplied Arles with water from the south side of the Alpilles hills, the basin acting as a header basin before the arcade. Later, the Eygalières branch from the north side of the Alpilles was joined to the basin. The Caparon branch was then diverted to power water-mills at Barbegal, changing the basin's function from convergence back to a header basin. After some decades, the Eygalières branch was also used to supply the mills, changing the basin into a distribution structure.
