We tested the potential for sand calcites to serve as a novel paleoclimate archive by investigating their age and formation conditions. Fontainebleau sand calcites are Pleistocene in age (based on ¹⁴C and U-Th dating) and were primarily formed during glacial periods. δ¹³C values increase with the de...
