Geochemical behavior of rare elements in Paleogene saline lake sediments of the Qaidam Basin, NE Tibetan Plateau

The Paleogene paleo-lake in the Qaidam Basin on NE Tibetan Plateau is one of the largest perennial inland saline lakes in China. Forty-nine samples collected from four depositional environments (shallow lake, lakeshore, sandy mudflat and gypsiferous mudflat) have been tested for major, trace and rare earth elements to study the geochemical behavior of rare elements (including trace and rare earth elements) in sediments of saline lakes. Based on...
