The 4.2 ka event in the central Mediterranean: New data from a Corchia speleothem (Apuan Alps, central Italy)
We present new data on the 4.2 ka event in the central Mediterranean from Corchia Cave (Tuscany, central Italy) stalagmite CC27. The stalagmite was analyzed for stable isotopes (δ13C and δ18O) and trace elements (Mg, U, P, Y), with all proxies showing a coherent phase of reduced cave recharge betwee...
