A volcanic tuff near the Carboniferous–Permian boundary, Taiyuan Formation, North China: Radioisotopic dating and global correlation

, 2020
A 66 cm thick volcanic ash fall tuff occurring within a thick coal deposit and containing a paleobotanical fossil lagerstatte in the Wuda coal district of North China has been dated as 298.34 ± 0.09 Ma.

Carboniferous

Geological Society, London, Memoirs, 1992
Abstract Carboniferous geology has developed very rapidly over the past two decades since ideas on sedimentology and new radiometric scales, together with new biostratigraphical schemes based on miospores, conodonts and foraminifera have been synthesized with ideas on plate tectonic processes, climatic changes and oscillations of sea level ...

The Devonian-Carboniferous boundary in Vietnam: Sustained ocean anoxia with a volcanic trigger for the Hangenberg Crisis?

Global and Planetary Change, 2019
The Devonian-Carboniferous transition (359 Ma) was a time of extreme climate and faunal change and is associated with the end-Devonian biodiversity crisis.

Devonian to carboniferous tectonic evolution of the Kangguer Ocean in the Eastern Tianshan, NW China: Insights from three episodes of granitoids

, 2019
Deciphering the tectonic evolution of the Kangguer Ocean is critical to understand the architecture of the Eastern Tianshan, NW China. Previous studies for the Kangguer Ocean mainly concentrated on final closure during the Latest Carboniferous to Permian.

A new Carboniferous–Permian intra‐oceanic subduction system in the North Tianshan (NW China): Implications for multiple accretionary tectonics of the southern Altaids

Geological Journal, 2019
The North Tianshan in NW China is a key to understanding the accretionary history of the southern Altaids. However, the tectonic setting of the North Tianshan in the Carboniferous‐Permian is debatable, and its amalgamation history is ambiguous. We report

Carboniferous

1993
Abstract The Carboniferous System in Western Canada Basin (Fig. 4E.1-4E.3) is a thick succesion of strata deposited on the downwarped and downfaulted western margin of the ancestral North American plate, the central to western cratonic platform, and southern Yukon Fold Belt.

Combined tectonic and paleogeographic controls on the genesis of bauxite in the Early Carboniferous to Permian Central Yangtze Island

Ore Geology Reviews, 2018
Two bauxite horizons, with a total reserve of 1.29 Bt, occur in the Lower Carboniferous and Lower Permian in the central South China Block. Different from other intracontinenal bauxites in China, which are genetically linked to the orogenesis along the ...
