Journal of Geophysical Research: Solid Earth, Volume 129, Issue 12, December 2024.Abstract Many of the world's rifts and rifted margins have developed within former orogens. The South China Sea (SCS) formed during Cenozoic rifting by utilizing pre‐existing orogenic structures, like thrust faults, thickened crust, and corresponding thermal weaknesses.

Geophysical Research Letters, Volume 51, Issue 18, 28 September 2024.Abstract We investigated the crustal radial anisotropy in the eastern South China Block (ESCB) with the F‐J multimodal ambient noise tomography. Well corresponding to widespread mid‐crustal low‐velocity zones in the VSV ${V}_{SV}$ model, a pronounced mid‐crustal channel of positive radial anisotropy is revealed.

Geophysical Research Letters, Volume 51, Issue 9, 16 May 2024.Abstract Geothermal fields emit remarkable amounts of mercury (Hg) to the environment. To address the source, fate and geochemical cycling of Hg in geothermal fields, we investigated Hg concentrations and isotopic compositions of hot spring water and fumarole gases from Rehai and Dagejia in SW‐China.
