Basic research for the geodynamics program [PDF]
Some objectives of this geodynamic program are: (1) optimal utilization of laser and VLBI observations as reference frames for geodynamics, (2) utilization of range difference observations in geodynamics, and (3) estimation techniques in crustal ...

Early earth geodynamics: cross examining the geological testimony
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2018 Many studies link the presence of continents on Earth to the operation of plate tectonics. Radiogenic isotope data have, however, long consigned the bulk of crust generation and preservation to the murky realm of the Precambrian Earth, where the ...

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins
AGU Advances, Volume 7, Issue 1, February 2026.Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

China organic-rich shale geologic features and special shale gas production issues
Journal of Rock Mechanics and Geotechnical Engineering, 2014 The depositional environment of organic-rich shale and the related tectonic evolution in China are rather different from those in North America. In China, organic-rich shale is not only deposited in marine environment, but also in non-marine environment:

Differentiating Plumes and Local Torus Segments of Enceladus
Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract Enceladus's south polar plumes and their surrounding torus segments (local plasma regions formed by plume material diffusion) are key to understanding its magnetospheric interaction; however, clear observational criteria to distinguish them remain lacking.

Modeling Geoid and Dynamic Topography From Tomography‐Based Thermo‐Chemical Mantle Convection
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.Abstract Mantle convection causes the most important contribution to the geoid and dynamic topography. With mantle density inferred from high‐resolution tomography models and numerical methods solving the governing equations of viscous mantle flow, the modeled geoid can fit the observations well.
