Abstract:

This dataset presents concentrations of rare earth elements in the sediment core of Donghu Lake. The sediment core is 73 cm in length, the upper layers (0-55 cm) recorded the history of environmental changes since ~1810 CE according to the 210Pb dating.

Keyword(s):

Dongting Lake; Lake sediment; Paleolimnology; Rare earth elements
