From: Quantifying chemomechanical weakening in muscovite mica with a simple micromechanical model
a An example load-depth curve for the four conditions tested. In order of increasing chemomechanical weakening, the dry condition, muscovite submerged in deionized water (DI water), pH 9.8 water, and pH 12 water are shown, with an inset showing the same at low loads. The largest events at intermediate load occur in the dry condition, and the largest events at low load occur in the pH 12 condition. b An example indent in the dry condition with detected bursts highlighted and the profile of a single example burst in the inset. Source data are provided as a Source Data file.
