Early–Late Carboniferous Tectonic Evolution of the Northern North China Craton (NE China): Constraints From Zircon Ages, Geochemistry, and Crustal Thickness Modeling

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 8, August 2026.
Abstract The tectonic evolution of the northern margin of the North China Craton (NCC) remains controversial. In this study, we obtained zircon U–Pb ages, geochemical data, and Sr–Nd isotopic data for volcanic rocks, and detrital zircon ages for sedimentary rocks from the Yufutun, Tongqigou, and Benxi formations in central‐southern Jilin Province, NE ...

The Ames impact structure, Oklahoma: New radioisotopic constraints and implications for North American impact chronology

Meteoritics &Planetary Science, Volume 61, Issue 8, Page 2103-2139, August 2026.
Abstract The Ames impact structure (Oklahoma) is thought to have formed during the Ordovician Meteor Event, based on conodont biostratigraphy of its crater fill. Here, U–Pb zircon dates from its impact‐melt portion, conducted using secondary ion mass spectrometry and laser ablation–inductively coupled plasma–mass spectrometry (n = 37 spots), yield a ...

Shell proteome of rhynchonelliform brachiopods

, 2015
7 pagesInternational audienceBrachiopods are a phylum of marine invertebrates that have an external bivalved shell to protect their living tissues. With few exceptions, this biomineralized structure is composed of calcite, mixed together with a minor ...

Sections in the western slope of the south urals perspective for the choice of the famennian regional boundary stratotype point

Литосфера, 2015
The Bol’shaya Barma, Akkyr, Ryauzyak and Kuk-Karauk sections in the western slope of the South Urals are considered to be perspective sections for the identification of Famennian Regional Boundary Stratotype Point (RBSP).

Crystal Organisation of Muscle Attachment Sites of Bivalved Marine Organisms: A Juxtaposition Between Brachiopod and Bivalved Mollusc Shells

Crystals
The movement of valves of bivalved invertebrates is enabled through the action of muscles and the interplay between the muscles and the hinge ligament. The muscles that move the valves attach to their internal surface. To promote the structural integrity

Lower Silurian biostratigraphy of the Viirelaid core, western Estonia [PDF]

Estonian Journal of Earth Sciences, 2007
The distribution of five groups of fossils in the upper Llandovery (Telychian) and Wenlock of the Viirelaid core section, Estonia, is presented and discussed in terms of their biozones (conodonts and chitinozoans) and mutual positions (scolecodonts ...

The dawn of a dynasty: life strategies of Cambrian and Ordovician brachiopods [PDF]

, 2017
Brachiopods are among the first animal phyla to emerge from the Cambrian Explosion, rapidly diversifying to all major palaeocontinental blocks within 20 million years.
