Geschichtete Karbonate in römischen Wasserleitungen: ein neues Archiv für Umweltforschung und Archäologie
Mineralogie, Petrologie und Geochemie
Zusammenfassung der Projektergebnisse
Understanding our environment and the way it changes due to human and natural causes is crucial for the survival of humankind. Scientists have a responsibility to find new, unexplored sources that can shed light on past changes, and the reactions of society to such problems in the past. Environmental archives such as naturally forming layered carbonate deposits (tufa, travertine and speleothems) are a pivot in environmental studies since they record changes in climate and vegetation cover. Such archives are long time series, but they may have relatively low resolution, be absent in crucial areas and lack a direct link to ancient urban centers. In our study, we explored carbonate deposits (CaCO3) from Roman aqueducts in connection with civilization centers of the Roman Empire in France. We found that such carbonate deposits can give a wealth of information in archaeology, and additional data on environmental conditions during Roman time. Observations of carbonate from the Roman aqueducts of Cahors and Fréjus have shown, that environmental data are stored in such deposits, and that data on annual temperature, spring discharge (and indirectly precipitation) can be retrieved with an up to daily resolution. It is clear however, that aqueducts were a controlled environment, and that it is necessary to recognize and understand anthropogenic effects in the deposits before reliable environmental data can be retrieved. We therefore focused an important part our project time on the archaeological interpretation of the deposits, especially those of the roman aqueduct of Arles, and the Barbegal watermills fed by this aqueduct. The Barbegal mills were the first industrial complex in Europe, and we managed to obtain significant data on its operation and function, promoting the use of carbonate deposits to understand the use of ancient water systems. We obtained proof for cleaning operations of water systems where carbonate was removed; for temporary (months-long) close down of systems, which also showed that the mills were probably used to produce hard tack for local harbors, and not flour for a city; and we could reconstruct the hydraulics of gutters in the watermills that provided insight into some unique engineering solutions for this special pre-industrial complex.
