Exploring the Effects of Hydraulic Fracturing on the 2019 Mw 5.0 Weiyuan Earthquake in Sichuan, China

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract The seismicity inside the Sichuan Basin in southwest China has been dramatically intensified with the increase of shale gas exploitation recently. On 8 September 2019, an MW 5.0 earthquake struck Weiyuan County in the Sichuan Basin, representing the largest earthquake in the Weiyuan shale gas field.

Ocean acidification in the aftermath of the Marinoan glaciation [PDF]

open access: yes, 2014
Boron isotope patterns preserved in cap carbonates deposited in the aftermath of the younger Cryogenian (Marinoan, ca. 635 Ma) glaciation confirm a temporary ocean acidification event on the continental margin of the southern Congo craton, Namibia.

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.
