Deeply concealed half-graben at the SW margin of the East European Craton (SE Poland) — Evidence for Neoproterozoic rifting prior to the break-up of Rodinia

Journal of Palaeogeography, 2018
Baltica was one of continents formed as a result of Rodinia break-up 850–550 Ma. It was separated from Amazonia(?) by the Tornquist Ocean, the opening of which was preceded by Neoproterozoic extension in a network of continental rifts.

Fossil black smoker yields oxygen isotopic composition of Neoproterozoic seawater

Nature Communications, 2018
The evolution of the seawater oxygen isotopic composition (δ18O) through geological time remains controversial. Yet, the past δ18Oseawater is key to assess past seawater temperatures, providing insights into past climate change and life evolution.

Protracted High‐Grade Metamorphism and Slow Cooling in the Adirondacks Recalibrate Neoproterozoic Global Paleogeography

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The assembly and breakup of the supercontinent Rodinia set the stage for Earth system evolution through the Neoproterozoic Era. Laurentia, the central craton in Rodinia, lacks well‐dated paleomagnetic poles between ca. 990 Ma and 780 Ma. In this study, we develop new U‐Pb petrochronology and thermochronology data sets from zircon, garnet ...

Understanding Neoproterozoic geodynamics through Hafnium isotope arrays [PDF]

, 2020
The Neoproterozoic supercontinent Rodinia assembled by the collision of a global-scale subduction girdle at the end of the Mesoproterozoic. A new subduction girdle is not established until the assembly of Gondwana some 500 Ma later, at the end of the ...

Identifying Laurentian and SW Gondwana sources in the Neoproterozoic to Early Paleozoic metasedimentary rocks of the Sierras Pampeanas: Paleogeographic and tectonic implications

, 2016
The provenance of Neoproterozoic to Early Paleozoic sedimentary rocks in the Sierras Pampeanas has been established using U–Pb SHRIMP age determination of detrital zircons in twelve metasedimentary samples, with supplementary Hf and O isotope analyses of

Laurasian Seaway History During the Early Jurassic From Quantitative Mineralogy and Detrital Zircon Dating

Paleoceanography and Paleoclimatology, Volume 41, Issue 6, June 2026.
Abstract The Laurasian Seaway comprises a N‐S oriented trans‐Pangaean corridor linking Tethys to the Boreal Sea during the Jurassic, and direction of water flow has been the subject of considerable debate. The Llanbedr (Mochras Farm) borehole, Cardigan Bay Basin, Wales, is a uniquely informative record that comprises an expanded deep‐marine silty ...

Neoproterozoic granitic gneisses in the Chinese Central Tianshan Block: Implications for tectonic affinity and Precambrian crustal evolution

, 2015
The Chinese Tianshan is the southernmost orogenic terrane located in the long-lived accretionary Central Asian Orogenic Belt. Granitoid rocks are extensively exposed in the Chinese Tianshan, especially in its central part, known as the Chinese Central ...

Occurrence of a Cavity‐Nesting Tropical Swallow Is Associated to Riverbed Lithology

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Understanding the factors shaping species distribution is a key challenge in ecology and biogeography. While dispersal limitations, environmental features, and biotic interactions are commonly recognized as key determinants of species abundance and distribution, some species exhibit patchy distributions that remain hard to explain.

Late Paleoproterozoic-Neoproterozoic multi-rifting events in the North China Craton and their geological significance: A study advance and review

, 2015
An important Paleoproterozoic mobile belt event took place in the North China Craton (NCC), termed the Hutuo Movement. This event has been interpreted to represent cratonic reworking characterized by rifting-subduction-collision processes.
