THE STRUCTURE OF THE LITHOSPHERIC MANTLE OF THE SIBERAIN CRATON AND SEISMODYNAMICS OF DEFORMATION WAVES IN THE BAIKAL SEISMIC ZONE

open access: yesГеодинамика и тектонофизика, 2015
The evolution and specific features of seismogynamics of the Baikal zones are reviewed in the context of interactions between deep deformation waves and the regional structure of the lithospheric mantle.

Lithosphere thinning beneath west North China Craton: Evidence from geochemical and Sr-Nd-Hf isotope compositions of Jining basalts [PDF]

open access: yes, 2014
This study shows lithosphere evolution history in the west North China Craton (NCC) from the early Cretaceous to Quaternary by studying the major element, trace element and Sr-Nd-Hf isotope compositions in Jining basalts of 119.6-108.6. Ma, 23.5-21.9. Ma

A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

Termination of rapid exhumation of the Jiaodong Peninsula during the Early Cretaceous: implications for explosive gold mineralization

open access: yesFrontiers in Earth Science
The proven gold deposits in the Jiaodong Peninsula, North China Craton, exceed 5,500 tons; these deposits are termed “Jiaodong type” or “Craton destruction type” owing to their unique geological features.

Late Eocene to Early Oligocene (36–26 Ma) Rock Magnetism and Magnetostratigraphy of IODP Site U1553, Southwestern Pacific: Defying the Challenges of Carbonate Dilution and Reductive Diagenesis

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The late Eocene to early Oligocene is an intriguing Paleogene period in which the Earth climate state changed from Warmhouse to Coolhouse. Accurate age models are essential for investigating these climate transitions. The southwestern Pacific International Ocean Discovery Program (IODP) Site U1553, with its almost complete succession of the ...

Structure of the Mantle Keel of the Wyoming Craton and Its Relationship to Intracratonic Deformation and Magmatism

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Wyoming Craton is often cited as an example of decratonization, implying the removal of its lithospheric keel. However, numerous geophysical imaging studies indicate the presence of thick mantle lithosphere beneath much of the Wyoming Craton.

The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)

open access: yesSedimentology, Volume 73, Issue 3, Page 802-837, April 2026.
ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Seismic Constraints on Temperature, Partial Melt, and Lithosphere‐Asthenosphere Dynamics in the Southwestern United States

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The southwestern United States hosts well‐documented and dramatic variations in topography, seismicity, heat flow, magmatism, and seismic velocity structure. This region offers opportunities to investigate how processes such as temperature and partial melt are related to the Lithosphere‐Asthenosphere Boundary (LAB), and how they ultimately ...

Sedimentation record in the Konkan-Kerala Basin: implications for the evolution of the Western Ghats and the Western Indian passive margin [PDF]

open access: yes, 2007
The Konkan and Kerala Basins constitute a major depocentre for sediment from the onshore hinterland of Western India and as such provide a valuable record of the timing and magnitude of Cenozoic denudation along the continental margin.

Role of Complex Crustal and Basinal Structures in Onset of an Intracratonic Rift System: An Example From the Onshore Potiguar Basin, Brazilian Equatorial Margin

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Schematic evolution model of the Onshore Potiguar Basin, illustrating the role of complex crustal and basinal structures in the onset of this intracratonic rift system in NE Brazilian Equatorial Margin. Red arrows indicate the extensional direction and coloured areas on the surface are the Self‐Organizing Maps populations related to crystalline ...
