Abstract:
Presented here are stable isotopes (δ¹⁸O, δ¹³C) derived from the MV1 stalagmite. This sample was collected from Mata Virgem cave (11°37′27.07′′S, 47°29′19.04′′W) in the eastern region of the Brazilian tropical Savannah known as 'Cerrado'. The record spans from approximately 1834 – 1170 CE and ages were assigned based on the StalAge modeling software (Scholz and Hoffman, 2011). The record was sampled approximately every 0.04 cm along the growth axis.
