Abstract: 




Urban secondary carbonate deposits (USCD), such as the ones deposited in 
aqueducts, offer a possibility to reconstruct past water quality using trace 
elements combined with isotopic analyses. However, establishing their 
accurate chronology presents a challenge, and a combination of chronometers 
is required (e.g., U-Th, 14 C, lamina counting). The lecture will present the 
approaches developed and the results obtained from the study of USCD in the 
historic underground aqueducts of Paris. 



The lecture is within the framework of the Hungary-France bilateral project 
2023-1.2.4-TÉT-2023-00009 “Improvement of isotopic measurements for 
(paleo)environmental studies”, related to U-Th dating, and part of the visit 
of the French partner LSCE (PI Edwige Pons-Branchu) at ATOMKI (PI Marjan 
Temovski).
