摘要
The simultaneity and the regionality of the chemo-cycles are proved by cycle-to-cycle correlation integrated with conodont biostratigraphic correlation of the upper part of the Givetian (Devonian) between Liujing and Dale. The study indicates that these chemo-cycles with time spans of 0.10 Ma have an internal relation with paleoclimatic changes, and it might have an origin through Milankovitch eccentricity cyclicity.
