Milankovitch periodicities of 123 kyr(eccentricity), 35.6 kyr(obliquity), and 21.2 kyr(precession) were identified in geophysical logs of three Late Permian coals: 17#, 18#, and 17 + 18#, from the Songhe mining area i...

Carbonate strata of the Mesoproterozoic Wumishan Formation in the Jixian area near Tianjin are ~3300 m thick and were deposited over some 100 million years(from ~1310±20 Ma to ~1207±10 Ma).Metre-scale cycles(paraseq...

Due to their slow growth rates, seamount Co-rich crusts are very difficult to date with high resolution and precision. This paper is to test the use of orbital pacing on the growth profile of crusts to determine high-...

The regional distribution in different depositional facies belts is here regarded as an important criterion for defining and recognizing the various orders of sequences. The third-order sequence is possibly global in ...
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 ...
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 ...
