A 24 , 700-yr paleolimnological history from the Peruvian Andes

  title={A 24 , 700-yr paleolimnological history from the Peruvian Andes},
  author={Rachel Hillyer and Bryan G. Valencia and Mark B Bush and Miles R Silman and Miriam Steinitz-Kannan},
A new paleolimnological dataset from Lake Pacucha (13 °S, 3095 m elevation) in the Peruvian Andes provides evidence of changes in lake level over the past 24,700 yr. A late-glacial highstand in lake level gave way to an early-Holocene lowstand. This transition appears to have paralleled precessional changes that would have reduced insolation during the wet-season. The occurrence of benthic/salt-tolerant diatoms and CaCO3 deposition suggest that the lake had lost much of its volume by c. 10,000… CONTINUE READING
