Island Arc, Volume 34, Issue 1, January/December 2025.ABSTRACT An ostracod assemblage from the Late Ordovician (Katian) Phu Ngu Formation of northern Vietnam, South China paleoplate, yields typical Baltic and Laurentian‐affinity genera together with some endemic forms. Detailed paleontological and sedimentary analysis of the Phu Ngu Formation suggests it was deposited in a deeper marine forearc setting ...

Black Shale Lithofacies of the Wufeng–Longmaxi Formation in the Southeast Margin of Chongqing, China
Geofluids, Volume 2025, Issue 1, 2025.China’s shale gas has undergone nearly 20 years of exploration; unconventional oil and gas geological evaluation theories and research methods have been greatly enriched, but how to quickly, conveniently, and accurately identify the sweet spots of shale gas is still puzzling many researchers. This study focuses on the black shale of the Wufeng–Longmaxi

Geofluids, Volume 2025, Issue 1, 2025.Unconventional tight/shale gas reservoirs have gained significant attention in the energy sector. The importance of temperature and pressure in shale imbibition lies in their profound influence on the kinetics, rate, and ultimate amount of water uptake, which directly impacts the efficiency of gas production.

A database of detrital zircon geochronology ages of Cambrian to Paleogene deposits in South China
Geoscience Data Journal, Volume 11, Issue 4, Page 405-413, October 2024.Here, we had collect a database about the South China Phanerozoic detrital zircon geochronology data, and we published the database in DDE. We marked Kernel density estimates, ɛHf(t) vs. U‐Pb ages and the best age‐based multidimensional scaling plot from South China. Abstract Complications of detrital zircons databases provide a means for statistically

Journal of the Royal Society of New Zealand, Volume 54, Issue 5, Page 566-583, October 2024.ABSTRACT The 47 vertebrate type specimens held in the University of Otago Geology Department are catalogued in detail. A short history of the collection is followed by lists of the type specimens under the Classes Actinopterygii, Reptilia, Aves and Mammalia. A fish trace‐fossil is included at the end of the Actinopterygii.
