Elemental Mapping Reveals Selective Dolomitization in Tonian Stromatolites: Implications for Early Diagenesis and Paleoenvironmental Proxies

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Stromatolites archive critical information on Precambrian marine environments, but their geochemical signals are often obscured using complex diagenetic processes. Tonian stromatolites from the Weiji Formation, North China, show selective dolomitization in dark stromatolitic laminae, forming zoned dolomites.

Characteristics of Sediment Bacterial Community in Response to Environmental Impacts in a Sewage Polluted River [PDF]

open access: yes, 2016
The Jiaolai River is the main source of industrial and irrigation water for its catchment of 3900 km(2). Anthropogenic activities have caused heavy pollution of this river, but their impacts on biota have never been evaluated.

Strain Rates Along the Alpine‐Himalayan Belt From a Comprehensive GNSS Velocity Field

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract The Alpine‐Himalayan belt is one of Earth's most dynamic and complex regions, characterized by intense tectonic deformation and seismicity. Comprehensive analyses of continental‐scale crustal deformation and seismic hazards along this extensive orogenic belt require the compilation of large geodetic data sets.

Characterizing Geometrical Anisotropy of Petrophysical properties in the middle Shahejie formation, Liaohe Depression, China. [PDF]

open access: yes, 2016
Knowledge of reservoir body lateral extent is important information for estimation of hydrocarbon initially in place and the recoverable quantity. This study reports a stepwise approach to evaluate geometrical anisotropy of the rapidly changing alluvial ...

Diagenetic processes controlled by volcanic detritus of the Lower‐Middle Permian Shanxi and Shihezi sandstone formations, North Ordos Basin, China

open access: yesThe Depositional Record, Volume 11, Issue 5, Page 1645-1668, November 2025.
Comparisons of Lower‐Middle Permian Shanxi and Lower Shihezi formations from the North Ordos Basin reveal that different types and percentages of volcanic detritus induced by active magmatic cycles can significantly change diagenetic evolution and favourable reservoirs.

Modeling of non-point source nitrogen pollution from 1979 to 2008 in Jiaodong Peninsula, China [PDF]

open access: yes, 2014
Efforts to reduce land-based non-point source (NPS) pollutions from watersheds to coastal waters are ongoing all around the world. In this study, annual yield of NPS nitrogen (NPS-N) pollution in Jiaodong Peninsula, China from 1979 to 2008 was estimated.

Reconstruction of the Cenozoic deformation of the Bohai Bay Basin, North China

open access: yesBasin Research, 2020
Abstract A well‐constrained plate deformation model may lead to an improved understanding of sedimentary basin formation and the connection between subduction history and over‐riding plate deformation. Building quantitative models of basin kinematics and deformation remains challenging often due to the lack of comprehensive ...

Multiscale NMR Characterization in Shale: From Relaxation Mechanisms to Porous Media Research Frontiers

open access: yesEnergy Science &Engineering, Volume 13, Issue 11, Page 5777-5798, November 2025.
ABSTRACT Nuclear magnetic resonance (NMR), as an advanced non‐destructive and rapid measurement technology, has shown unique advantages in the evaluation of unconventional shale reservoirs. This paper systematically introduces the fundamental principles of NMR spectroscopy and relaxation theory in porous media and comprehensively analyzes the ...
