Geochemical data from sediment core M125-67-4

The data set has been obtained on gravity core M125-67-4 from off the Jequitinhonha River, East Brazil. The obtained proxies described the hydrological conditions in the river's hinterland over the past ~ 5000 years as measure of fluctuations in the South American Summer Monsoon intensity. XRF-...
