Uniformity of the upper Famennian Milankovitch cycle in China

Chinese Science Bulletin, 2000
Research on chemo-biostratigraphy reveals that the periodic fluctuation of Ce/La ratios in carbonate sequence may reflect Milankovitch 100 ka eccentricity cyclicity. The Ce/La curve of the upper Famennian of Huangmao (Guangxi) may be well correlated to that of Muhua (Guizhou) and of Mid-Tarim (Xinjiang).
