High‐Resolution Tomography for the Upper‐Mantle Structure in North China by Full‐Waveform Inversion of Teleseismic P Wave and Its Codas

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract We investigate the structure and tectonic environment in the crust and upper mantle beneath the North China Craton (NCC) by conducting a full‐waveform inversion of teleseismic P and its coda waves from densely distributed broadband seismic stations. A high‐resolution model involving P‐ and S‐wave velocities as well as density is constructed by

Thermochemical Structure of the Superior Craton and Environs: Implications for the Evolution and Preservation of Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems
The Archean Superior craton was formed by the assemblage of continental and oceanic terranes at ∼2.6 Ga. The craton is surrounded by multiple Proterozoic mobile belts, including the Paleoproterozoic Trans‐Hudson Orogen which brought together the Superior

Geochemical criteria for identifying diamond-bearing areas [PDF]

E3S Web of Conferences
The paper demonstrates that diamondiferous objects may be pinpointed even by the middle-scale geochemical surveys. Relevant criteria were developed to identify and classify such objects by their prospectivity.

Correlative X‐Ray and Neutron Tomography of Microbial Biosignatures: Perspectives for Mars Sample Return

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.

Late Mesozoic Intracontinental Deformation in the Northern Margin of the North China Craton: A Case Study From the Shangyi Basin, Northwestern Hebei Province, China

Frontiers in Earth Science, 2021
During the late Mesozoic, the East Asian continent underwent a complex tectonic history due to multiple episodes of plate convergence. How the crust responds to the multiple plate convergence in the North China Craton (NCC) remains unclear.

Groundwater Connectivity and Buffering in Western Australian Hypersaline Lakes: Implications for Late‐Stage Martian Lacustrine Systems

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Thousands of saline to hypersaline lakes exist across the Yilgarn Craton in Western Australia, representing potential Mars analogs with diverse and varying salinity, pH, and oxygen conditions that remain poorly constrained. Here, we report geochemical trends in lake waters that vary across wet‐dry cycles as well as with regional location and ...

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1288-1308, July 2026.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...
