Absolute palaeointensity estimates from Precambrian India and the long-term thermal evolution of the Earth Open
SUMMARY Despite significant progress in palaeomagnetic research over the last century, the origin, evolution and long-term behaviour of the geomagnetic field remains poorly understood. One significant open question is when and how the inne…

Provenance and tectonic evolution of the forearc basin along the northwestern Central Qilian belt, northeastern Tibet Open
The age and properties of detrital zircon grains in a forearc basin provide crucial information on the history of convergent plate margins. These data can be used to constrain provenance dispersal patterns, establish source-to-sink relatio…

Paleomagnetic Constraints on the Rapid Plate Shift of North China Block During the Jurassic From ∼155 Ma Dykes and Sills Open
A large‐scale apparent polar wander occurred during the Jurassic interval, which is interpreted as true polar wander (TPW). As the motion is nearly orthogonal to the TPW axis, the North China Block (NCB) experienced the largest latitudinal…

Neoproterozoic reorganization of the Circum- Mozambique orogens and growth of megacontinent Gondwana Open
The serpentine orogenic belts that formed during the Neoproterozoic assembly of Gondwana resulted in geodynamic changes on the planet in advance of the Cambrian radiation. The details of Gondwana assembly associated with the closure of the…

The enduring Ediacaran paleomagnetic enigma Open
The Ediacaran Period was an interval of significant global transformation, marked by major changes in the biosphere, cryosphere, hydrosphere and atmosphere, and possibly the solid Earth. A better understanding of this interval is thus impo…

Pangea is a complete supercontinent: paleomagnetic evidence from North China Open
Alfred Wegener proposed the idea of a supercontinent, which he called Pangea about one century ago. The idea led directly to the hypothesis of continental drift, which eventually evolved into the theory of plate tectonics. Pangea is tradit…

The drift history of the Dharwar Craton and India from 2.37 Ga to 1.01 Ga with refinements for an initial Rodinia configuration Open
Coupled paleomagnetic and geochronologic data derived from mafic dykes provide valuable records of continental movement. To reconstruct the Proterozoic paleogeographic history of Peninsular India, we report paleomagnetic directions and U-P…

Stinging News: ‘Dickinsonia’ discovered in the Upper Vindhyan of India Not Worth the Buzz Open
A recent report of Dickinsonia tenuis ‘hiding in plain sight’ at the Bhimbetka rock shelters in rocks of the Maihar sandstone (Upper Vindhyan) has important implications for paleogeography and the age of the Upper Vindhyan. We visited the …

Paleomagnetism of late Cretaceous dykes in the Gangdese belt: New constraints on the position and structure of the southern margin of Asia prior to the India-Asia collision Open
This paper report paleomagnetic data from late Cretaceous diorite dykes that sub-vertically intrude granodiorites in the eastern Gangdese belt near the city of Lhasa. Our research goals are to provide further constraints on pre-collisional…

A Short Note on the Age of the Marwar Supergroup, NW India Open
We report a summary of geochronological data derived from detrital zircons in the Marwar Supergroup, Rajasthan, India. Although the age of deposition for the Marwar sequence was inferred to be post-Cryogenian, there is a lack of any direct…

Episodic Neoproterozoic extension-related magmatism in the Altyn Tagh, NW China: implications for extension and breakup processes of Rodinia supercontinent Open
Episodic Neoproterozoic magmatic suites in the Altyn Tagh, NW China, are thought to be related break-up of the Rodinia supercontinent. These suites resulted from long-term extension of the lithosphere during orogenic collapse and subsequen…

Protracted magmatism and magnetization around the McClure Mountain alkaline igneous complex Open
The McClure Mountain–Iron Mountain igneous complex is an alkalic intrusive center in the northern Wet Mountains of southern Colorado. It was emplaced in early Cambrian time into gneissic/granitic 1.75–1.45 Ga Proterozoic host rocks. Numero…

The Jurassic Yeba Formation in the Gangdese arc of S. Tibet: implications for upper plate extension in the Lhasa terrane Open
The formation of the Jurassic Xiongcun porphyry copper deposit, within the Gangdese magmatic belt of southern Tibet, took place coincident with subduction of the Neotethyan oceanic lithosphere. Although the Yeba Formation (coeval and co-ma…

Assessing the intersection/remagnetization puzzle with synthetic apparent polar wander paths Open
Palaeomagnetic data are of variable quality. To assist in a systematic assessment of data, a set of seven quality criteria (VQ1–VQ7) were introduced by Van der Voo. The last of those criteria 'VQ7' concerns the possibility of remagnetizati…

Does the planetary dynamo go cycling on? Re-examining the evidence for cycles in magnetic reversal rate Open
The record of reversals of the geomagnetic field has played an integral role in the development of plate tectonic theory. Statistical analyses of the reversal record are aimed at detailing patterns and linking those patterns to core–mantle…

Ediacaran–Cambrian paleogeography of Baltica: A paleomagnetic view from a diamond pit on the White Sea east coast Open
The controversial late Ediacaran to Cambrian paleogeography is largely due to the paucity and low reliability of available paleomagnetic poles. Baltica is a prime example of these issues. Previously published paleomagnetic results from a t…
