A 500‐kyr Pluvial Interval Triggered Lacustrine Carbon Burial in Late Cretaceous East Asia

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The early Late Cretaceous hothouse was featured by intense storms and a prevailing monsoon climate, yet direct evidence for regional extreme precipitation events is rare. Here, we reconstruct local weathering and hydrological processes using magnesium and strontium isotopes (δ26Mg and 87Sr/86Sr) from lacustrine dolostones in the Upper ...

Isotopic evidence for enhanced tidal flat productivity driven by nutrient‐rich submarine groundwater discharge

open access: yesLimnology and Oceanography, Volume 71, Issue 2, February 2026.
Abstract Submarine groundwater discharge (SGD) is well recognized as a significant nutrient source in coastal oceans. However, direct evidence linking SGD‐derived nutrients to biological production across trophic levels remains limited. Here, we investigated the influence of SGD on a tidal flat ecosystem on the west coast of Korea, where high ...

Differences in oil and gas enrichment in slope belts of rift basins and main controlling factors for hydrocarbon accumulation: a case study of Sanhe Sub-sag in Jinhu Sag, Subei Basin

open access: yesShiyou shiyan dizhi, 2022
The slope zone of rift basin is close to the hydrocarbon generation center of deep depression zone, and is favorable area for oil and gas accumulation. Due to the heterogeneity of the development of fault and sedimentary system in slope zone, oil and gas

Formation conditions of shale oil and favorable targets in the second member of Paleogene Funing Formation in Qintong Sag, Subei Basin

open access: yesShiyou shiyan dizhi, 2021
The favorable targets of shale oil exploration were optimized based on the analyses of hydrocarbon generation, reservoir conditions and oil content of the shale sections in the second member of Paleogene Funing Formation in the Qintong Sag, Subei Basin ...

Progress and direction of 3D seismic exploration in Qintong Sag of Subei Basin

open access: yesYouqicang pingjia yu kaifa, 2023
Qintong Sag of Subei Basin has high abundance of oil and gas resources and great exploration potential, but the geological target has the complex characteristics of “thin, broken, small, scattered and hidden”. Since 1989, there is a series of seismic technical breakthroughs in this area.

Numerical Simulations of Hydraulic Fracturing in Carbonate‐Type Hot Dry Rock Reservoirs Based on the Coupled Thermo‐Hydraulic‐Mechanical‐Damage (THMD) Model

open access: yesEnergy Science &Engineering, Volume 13, Issue 12, Page 5821-5834, December 2025.
ABSTRACT Hydraulic fracturing technology is widely used in Enhanced Geothermal System (EGS) projects to induce fractures and enhance the permeability of thermal reservoirs. The hydraulic fracturing process of hot dry rock (HDR) is actually a multiphysics coupling process that couples the heat transfer field, seepage field, stress field, and damage ...

A Piece of the Puzzle: Evaluating the Effectiveness of the Newly Designated Qilianshan National Park (China) and Its Contribution to Snow Leopard (Panthera Uncia) Habitat Connectivity 拼图之一:评估新建祁连山国家公园 (中国) 的有效性及其对雪豹 (Panthera Uncia) 栖息地连通性的贡献

open access: yesIntegrative Conservation, Volume 4, Issue 3, Page 287-301, September 2025.
Qilianshan National Park covers approximately 40% of core snow leopard habitat patches and 50% of movement corridors between patches. Including more of these important areas within the park boundaries should be considered, as the Qilianshan National Park sits at a pivotal juncture between critical snow leopard habitat in China and Mongolia, and may ...

High‐Resolution Lithospheric Shear Velocity Structure of the Suqian Segment of the Tanlu Fault Zone From Ambient Noise Tomography

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 5, May 2025.
Abstract To understand causes of the Suqian seismic gap and the 1668 M8.5 Tancheng earthquake, we determine a new 3‐D S‐wave velocity (Vs) model of the lithosphere under the Suqian segment of the Tanlu fault zone in eastern China using ambient noise tomography. Rayleigh wave phase velocity dispersions at periods of 5–33 s are collected from seismograms

Multiple Stages of Strike‐slip Movement and the Propagation of the Tan–Lu Fault Zone, East Asia

open access: yesActa Geologica Sinica - English Edition, Volume 99, Issue 2, Page 352-369, April 2025.
Abstract The approximately 3000 km long Tan–Lu fault zone (TLFZ) in East Asia is the longest continental strike‐slip fault zone in the world and exemplifies how such a fault zone forms and propagates on a continental scale. Structural and geochronological data from the TLFZ and surrounding regions indicate that the fault zone originated as NE/SW ...

Spatial Heterogeneity of Plant‐Level CCUS Investment Decisions in China's Cement Industry Under Various Policy Incentives

open access: yesEarth's Future, Volume 13, Issue 3, March 2025.
Abstract Carbon Capture, Utilization, and Storage (CCUS) is widely regarded as a critical technology for achieving deep decarbonization in the cement industry. However, limited research has focused on its plant‐level CCUS investment decisions, especially considering geographic heterogeneity based on the national source‐sink matching optimization.
