Sediment geochemistry and facies analysis as tools to interpret the paleolandscape evolution and pre-hispanic settlement dynamics on the eastern shore of Lake Texcoco (Mexico)
Integrating Geomorphology, Geology, and Geochemical Parameters to Understand the Preservation Status and Spatial Distribution of Archaeological Iron Objects Related to the 235 ce Roman–Germanic Harzho…
With more than 2000 excavated archaeological iron artifacts, the Roman–Germanic conflict site Harzhorn is among the best‐preserved battlefields from Classical Antiquity. The Harzhorn hogback, with its steep front face oriented to the north, is situated perpendicular to an important north–south passage west of the Harz Mountains in central Germany. The geological setting shows abrupt transitions at the surface between different Triassic and Quater…

Evaluating possible prehistoric cave art in the central Mediterranean
Watering the desert
The phenomenon of very extended desert oases settlements, mega-sites featuring complex irrigation systems and monumental walls has long been observed in Northern Arabia. In the past, it has been linked to the settling down of nomadic components of the population and dated through archaeological material to the Late Bronze or Iron Ages (late second to mid-first millennium BCE). Since 2014 we have been investigating this development through the cas…
The landscape of the Late Bronze Age royal tomb of Seddin (NE Germany)
The monumental Late Bonze Age royal tomb of Seddin is located in the old morainic landscape of the Prignitz region, northeastern Germany. Together with other richly equipped burials and a row of stone pits in its direct vicinity, it provides evidence for the presence of an elite from the nineth to sixth centuries BCE in this region. Our map emphasizes the well-chosen location of the royal tomb in relation to the spatial arrangement of other archa…
Lateglacial–Holocene environments and human occupation in the Upper Lena region of Eastern Siberia derived from sedimentary and zooarchaeological data from Lake Ochaul
In the current study, different geochemical and biological proxies, including pollen, non-pollen palynomorphs, ostracods and molluscs, from an AMS radiocarbon-dated sediment core from Lake Ochaul (54°14′N, 106°28′E; 641 m a.s.l.) are presented and discussed. Ochaul is a fresh-water lake and an archaeological site situated ca. 100 km northwest of Lake Baikal in the upper reaches of the Lena River. The 260-cm-long sedimentary record presented here …
Imprints of the Little Ice Age and the severe earthquake of AD 2001 on the aquatic ecosystem of a tropical maar lake in El Salvador
Using a 530-year sediment record from the maar Lake Apastepeque, El Salvador, and based on diverse geochemical and biological (cladocerans, chironomids, diatoms, ostracods, testate amoebae) indicators, we estimated climatic and environmental alterations during the Little Ice Age (LIA) and reconstructed the recent history of the lake. Results demonstrate relatively humid conditions in the mid-elevations (500 m a.s.l.) of El Salvador during most pa…
Late Pleistocene hydrological settings at world heritage Tsodilo Hills (NW Kalahari, Botswana), a site of ancient human occupation
Based on genetic studies, a Pleistocene Kalahari “palaeo-wetland”, which spanned the region of the Okavango Delta and the Makgadikgadi Basin, was recently considered the geographic origin of evolutionary modern humans. It was proposed that subsequent out-of-homeland migration was induced by climate shifts. The Tsodilo Hills, which are in relative proximity to the Okavango Delta, represent a site of ancient human occupation since at least 100 ka. …
On-Site VIS-NIR Spectral Reflectance and Colour Measurements—A Fast and Inexpensive Alternative for Delineating Sediment Layers Quantitatively? A Case Study from a Monumental Bronze Age Burial Mound (…
Quantitative sediment analyses performed in the laboratory are often used throughout archaeological excavations to critically reflect on-site stratigraphic delineation. Established methods are, however, often time-consuming and expensive. Recent studies suggest that systematic image analysis can objectivise the delineation of stratigraphic layers based on fast quantitative spectral measurements. The presented study examines how these assumptions …
Living at the wadi – integrating geomorphology and archaeology at the oasis of Qurayyah (NW Arabia)
The archaeological site Qurayyah, situated in the NW of the Tabuk Province of Saudi Arabia, has been repeatedly described as one of the largest and most significant oases of Northwestern Arabia. Human occupation in the oasis started at least from the early Holocene and continued to the Nabatean, Roman and late Byzantine period. The hydrologically favored position results from its specific geomorphological location where the plateaus fade towards …
Reconstructing human–landscape interactions in the context of ancient iron smelting on Elba Island, Italy, using sedimentological evidence
We reconstruct human–landscape interactions in the context of ancient bloomery smelting on Elba Island, Tyrrhenian Sea, based on sedimentological evidence. Elba was, together with Populonia, the center of iron production in antiquity (mid‐6th century B.C.E. to 1st century C.E.). The sediment sequences obtained by vibracoring in the Campo plain reveal that the Holocene transgression triggered aggradation during the Early–Middle Holocene (>5.4 ka c…
Lateglacial And Early Holocene Environments And Human Occupation In Brandenburg, Eastern Germany
The paper reports on the results of the pollen, plant macrofossil and geochemical analyses and the AMS 14C-based chronology of the «Rüdersdorf» outcrop situated east of Berlin in Brandenburg (Germany). The postglacial landscape changed from an open one to generally forested by ca. 14 cal. kyr BP. Woody plants (mainly birch and pine) contributed up to 85% to the pollen assemblages ca. 13.4–12.5 cal. kyr BP. The subsequent Younger Dryas ( YD) inter…

Two Iron-Age Settlement Sites in Germany
Geophysical exploration of archaeological sites has been a successful tool becoming more and more popular in the last decades. Many archaeological features can be detected with magnetic gradiometry (MGR), such as fire places, burned loam, metal artifacts, or other remnants, which produce a remanent magnetic signal detectable on the surface. However, as magnetic minerals are also present in natural settings, e.g. sedimentary and magmatic rocks and…

The Dahomey Gap
The Dahomey Gap, a savanna corridor interrupting the zonal West African rain forest, did not exist during the mid-Holocene. The pollen diagram from Lac Sélé (7°9'N, 2°26'E) indicates that in southern Benin a semi-evergreen rainforest prevailed between c. 8400 and 4500 cal. yr BP. The mid-Holocene marine transgression caused a spread of mangrove forest along the inland lagoons. Pollen analysis and geochemistry indicate that the Dahomey Gap became …

Hydrological response of an east-Saharan palaeolake (NW Sudan) to early-Holocene climate
We present a palaeolimnological record in western Nubia (NW Sudan, eastern Sahara) isolated from large-scale artesian systems and thus reflecting hydrological changes resulting from local rainfall. Past changes in lake water chemistry and water depth are interpreted by combining results from biological indicators (diatoms, ostracodes and charophytes) with geochemical and stable oxygen and carbon isotope data. Palaeolake Gureinat existed from ~10.…
Paleoclimatic implications of late quaternary lacustrine sediments in Western Nubia, Sudan
Owing to the hypercontinental location of Western Nubia, secular fluctuations of climate have been filtered and wet phases can be considered as representative of conditions throughout the southeastern Sahara. The study area is crossed by the 20-mm isohyet; between 9300 and about 4000 yr B.P., however, there were widespread lake and swamp environments with freshwater molluscs, ostracods, and diatoms, and a species-rich savanna mammal fauna. The ce…
Late Quaternary Climate and Vegetation of the Sudanian Zone of Northeast Nigeria
The Lake Tilla crater lake in northeastern Nigeria (10°23′N, 12°08′E) provides a ca. 17,000 14 C yr multiproxy record of the environmental history of a Sudanian savanna in West Africa. Evaluation of pollen, diatoms, and sedimentary geochemistry from cores suggests that dry climatic conditions prevailed throughout the late Pleistocene. Before the onset of the Holocene, the slow rise in lake levels was interrupted by a distinct dry event between ca…
