Basin Research, Volume 36, Issue 6, November–December 2024.First detrital zircon provenance study of the Billefjorden Group on Bjørnøya, Svalbard. The East Greenland Caledonides formed a long‐lived source terrain in northeast Greenland. Syn‐sedimentary faulting, drainage shifts and changing fluvial styles have little influence on detrital zircon age spectrum.

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).

LATE DEVONIAN CONODONTS FROM THE HOJEDK SECTION, KERMAN PROVINCE, SOUTHEASTERN IRAN
Rivista Italiana di Paleontologia e Stratigrafia, 2008 Conodonts (34 species and subspecies) from the Hojedk section north of Kerman span the late Givetian to early Famennian. The new data suggest that Devonian biostromes in central and eastern Iran were deposited on differing levels, and that the currently ...
