Abstract

In a pilot study, the rare earth elements and yttrium (REE when discussed without Y or REY with Y) were measured by inductively-coupled plasma mass spectrometry (ICP-MS) on a stalagmite (SJ3) from northeast Sichuan, Central China. This stalagmite was dated by the thermal ionization mass spectrometry (TIMS) 230Th method to between 38 and 10 thousand years before present (ka BP). The REY geochemical indices, including the concentrations, Lanthanum, Cerium and Yttrium anomalies and the fractionation between light and heavy REE (LREE and HREE), display significant stadial-interstadial changes corresponding to variations in past climates and environments. The North American Shale Composite (NASC)..
