Compaction creep of quartz sand at 400-600°C: Experimental evidence for dissolution-controlled pressure solution

Intergranular pressure solution (IPS) is an important compaction and deformation mechanism in quartzose rocks, but the kinetics and rate-controlling process remain unclear. The aim of the present study is to test microphysical models for compaction creep by IPS against isostatic hot pressing experiments performed on quartz sand under conditions...

Fluid-assisted healing processes in gouge-bearing faults Insights from experiments on a rock analogue system

On the basis of both experimental and field studies, solution transfer processes are expected to be important in contributing to fault strength recovery (healing) under the hydrothermal conditions prevailing in large parts of the seismogenic zone. However, most experimental work on healing effects in faults has been done using quartzo...
