This paper is an in-depth analysis of the taphonomy of the site and in particular of the best preserved layer 13. Few settlements have experienced a comparable interdisciplinary study on the mechanisms that governed the deposition of the archaeological remains.

In 2010 a large scale rescue excavation of a waterlogged neolithic site in the center of Zurich took place. 3000 Square meters of aracheological deposits with organic preservation were documented. More than 20´000 wood samples were taken. The deposits of eight settlement phases between 3234 and 2727 BC werde dated dendrochronologically. This first of three volumes presents the archaeological deposits and their environment in an interdisciplinary approach. The disciplines involved are Archaeology, Sedimentology, Geology, Geotechnics, Dendroarchaeology and Micromorphology

Lakeside settlements can be regarded as a special type of archaeological site, as, thanks to their location near the shoreline, or even in the lake, various kinds of organic remains have been preserved under waterlogged conditions. This paper presents the results of six-studied Neolithic lake dwellings from Switzerland. A series of natural and anthropogenic site formation processes were identified through micromorphological analysis and have been compared with natural processes in peatlands. The main processes can be summarized as follows: in the littoral zone a carbonate lake marl stratum accumulated prior to construction of the settlement. During lake regressions, the shore platform became dry and the settlements were established. Throughout the period of occupation, anthropogenic processes led to the accumulation of organic layers. The depositional regime can be characterized as paludal, dominated by constant humidity, and rapid covering of the remains. Some parts of the anthropogenic accumulations have been affected by erosion and reworking processes as a result of lake flooding, and runoff from the hinterland. Finally, the degradation of organic matter occurred only during dry phases when the groundwater level dropped. Seasonality was of great importance in this kind of milieu throughout the various processes described above. © 2013 Wiley Periodicals, Inc.

The Alpenquai lake-dwelling is located on Lake Zurich, and can be considered as one of the rare Late Bronze Age lake-dwellings with a pronounced organic-rich cultural layer in the northern Circum-Alpine region. Within a larger research project, investigating the final abandonment of the lakeshores in the Circum-Alpine area at the end of the Late Bronze Age, this settlement has been investigated using a multidisciplinary research design. Combining micromorphology, archaeobotany, palynology, archaeozoology and material culture studies, the formation of the site is reconstructed, and the reasons for its final abandonment are sought. A highly dynamic lake system that caused a lake water level rise before 900 BC, a regression in the second half of the 9th century BC, and a later transgression, could be detected. The settlement appears to have been established during the lake regression, and abandoned during the transgression, proving a high degree of environmental adaptation by its inhabitants.
