Quantitative Provenance Analysis of the Yangtze and Yellow River Sediments Through Detrital Zircon U‐Pb Geochronology Using an XGBoost Machine Learning Algorithm

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Over the past two decades, a large number of zircon U‐Pb ages from the Yangtze and Yellow River Basins have been published, yet distinguishing the sources of sediment between these regions remains challenging. Issues related to sampling, analytical methods, and biases complicate the interpretation of detrital zircon geochronology.

Multidimensional Characterization of Formation Damage Mechanisms in Ancient Carbonate Reservoirs: Synergistic Effects of Inorganic‐Organic Interactions

open access: yesEnergy Science &Engineering, Volume 13, Issue 6, Page 2663-2671, June 2025.
ABSTRACT Formation clogging in carbonate gas reservoirs is a significant challenge in natural gas extraction, particularly due to the complex mineral composition and physicochemical characteristics of carbonate rocks, which make clogging phenomena even more complex. This study aims to delve into the formation mechanisms of formation plugs in carbonate

New Pattern of Uplift‐Depression of the Pre‐Cambrian Basement in the Sichuan Basin: Constraints From Multi‐Seismic Parameter Imaging

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract The structural configuration of the pre‐Cambrian basement in the Sichuan Basin, a highly promising region for hydrocarbon exploration, has been a subject of long‐standing debate. Here, we determined the fine‐scale three‐dimensional seismic models of the Sichuan Basin using 187,356 high‐quality P‐ and S‐wave travel time pairs recorded by 627 ...
