Title: Influence of fluid-assisted healing on fault permeability structure
Abstract: Micro-cracks in fault damage zones can heal through diffusive mass transfer controlled by temperature and pressure. The diffusion of pore fluid pressure in fault damage zones...
Title: New insights to lunar formation through Apollo sample analysis
Abstract: The Moon provides a unique snapshot of the early Earth. Formed from the Earth by a giant impact (or impacts), the Moon has been unaffected by the large-scale reworking the Earth experiences. Analyzing a suite of samples from the Apollo missions for Hf and W provides information on the Moon's formation 4.51 billion years ago (around 50 million years after solar system formation), as well as its subsequent evolution. This can, in turn,...
Episodic Plate Motion and Thermal Structure in Subduction Zones Caused by Slab Folding in the Transition Zone
Abstract: Although most present-day subduction zones are in trench retreat, plate reconstructions and geological observations show that individual margins experience episodes of advancing, retreating or stationary trench motion with time-variable subduction rates. However, most laboratory and numerical simulations predict steady plate velocities and sustained trench retreat unless the slab experiences folding in the...
