The Impact of Erosion Efficiency on Rift‐Inversion Orogen Evolution: Implications for Serpentinization‐Derived Natural H2 Resources

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Natural hydrogen gas (H2) generated through the serpentinization of mantle rocks is a possible source of clean energy. For efficient serpentinization and large‐scale H2 generation to occur, mantle rocks need to be brought near the surface (exhumed) into a favorable temperature range (the serpentinization window) and in contact with water. Rift‐

The Zaozigou orogenic gold-antimony deposit, West Qinling Orogen, China: Structural controls on multiple mineralization events

Geological Society of America Bulletin
Orogenic gold deposits are generally thought to represent one perhaps protracted event. However, recent research on orogenic gold deposits increasingly offers evidence for some deposits forming through multiple and clearly discreet hydrothermal episodes.
