Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

open access: yesGeological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

Assessing and Explaining Human–Nature Coordination at the County Scale in China: Combining an Interpretable Spatiotemporal Graph Neural Network and Difference‐In‐Differences

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Coordinating high‐intensity human activities with fragile ecosystems remains a major challenge for global sustainability. Accurate assessment of human–nature coordination (HNC) is critical, yet county‐level variations, underlying drivers, and responses to ecological zoning have seldom been examined simultaneously within a unified framework. We
