We performed isotopic analyses of Carboniferous brachiopod shells from the Russian Platform to examine global and regional environmental change along the western and eastern margins of Laurussia during the formation of Pangea, and specifically to examine the isotopic evidence for the onset of mid-Carboniferous glaciation. Shell preservation was evaluated from shell microstructure, cathodoluminescence,...
Loess and paleosol samples from three distant sections (Xining, Xifeng, Jixian) of the Chinese Loess Plateau were analyzed for chemical and Nd-Sr isotopic compositions in order to obtain information about the paleoclimatic variation during the last 140 ka. These three sections represent three different climatic conditions, from arid in the west (Xining) to more humid in the east (Jixian) across the...
