The
character of deposition in lacustrine sedimentary systems is closely linked to
climatic and hydrologic change, and as such, their stratigraphic record can
provide important information on paleoclimate changes. In this study, Wang et al. examine Pliocene-Quaternary
lithofacies and stratigraphy of a ~kilometer long core from the western Qaidam
Basin of China. Integrating magnetostratigraphy with lithofacies facilitate semi-quantitative
interpretation of lake level fluctuations. Collectively, these data provide
sedimentologic evidence for long-term
change from a semi-deep fresh lake system to a playa system, associated with stepwise
Pliocene-Pleistocene drying
of the Asian inland forced by changes of global ice volume.
