Tectonic relationship between the Kelameili range and the Dajing depression: Insights into the Carboniferous tectonic-sedimentary framework

Petroleum Exploration and Development, 2020
Based on comprehensive analysis of typical outcrops, latest deep wells drilled and high resolution seismic profiles in the study area, we examined the geologic structure of the Kelameili range, and analyzed the structural relationship between the ...

UV-B radiation was the Devonian-Carboniferous boundary terrestrial extinction kill mechanism

Science Advances, 2020
A brief UV-B burst, during a climatic warming interval, collapsed the Devonian-Carboniferous boundary terrestrial ecosystem. There is an unexplained terrestrial mass extinction at the Devonian-Carboniferous boundary (359 million years ago). The discovery

Carbonodraco lundi gen et sp. nov., the oldest parareptile, from Linton, Ohio, and new insights into the early radiation of reptiles [PDF]

Royal Society Open Science, 2019
Redescription of the holotype specimen of Cephalerpeton ventriarmatum Moodie, 1912, from the Middle Pennsylvanian (Moscovian) Francis Creek Shale of Mazon Creek, Illinois, confirms that it is a basal eureptile with close postcranial similarities to other

Bashkirian rugose corals from the Carboniferous Mattson Formation in the Liard Basin, northwest Canada—stratigraphic and paleobiogeographic implications [PDF]

Acta Palaeontologica Polonica, 2019
Colonies of the rugose corals Nemistium liardense sp. nov. and Heritschioides simplex sp. nov. were collected from limestone in the upper member of the Mattson Formation in the Liard Range in the Northwest Territories and are the only known identifiable ...

U-Pb-Hf isotopic data from detrital zircons in late Carboniferous and Mid-Late Triassic sandstones, and also Carboniferous granites from the Tauride and Anatolide continental units in S Turkey: implications for Tethyan palaeogeography

Soviet Economy, 2020
Zircons from Carboniferous sandstones (three samples) and Mid-Late Triassic sandstones (four samples) from the Tauride and Anatolide continental units were analysed for U-Pb-Hf isotopes.

Variscan sourcing of Westphalian (Pennsylvanian) sandstones in the Canobie Coalfield, UK [PDF]

, 2010
The zircon age spectrum in a sample from the Canonbie Bridge Sandstone Formation (Asturian) of southern Scotland contains two main peaks. One is Early Carboniferous in age (348– 318 Ma), and corresponds to the age of igneous activity during the ...
