Model codes microphysical model for phyllosilicate frictional behaviour

This dataset contains a series of MATLAB codes in which the friction coefficient of pure phyllosilicate gouges is predicted as a function of porosity and grain size, relative humidity, normal stress and slip velocity. The codes are based on a microphysical model for phyllosilicate friction that assumes that shearing is controlled by sliding along (001) grain/platelet interfaces operating in series with removal of overlapping grain edge barriers by basal cleavage. Please see our publication in Journal of Geophysical Research - Solid Earth for details.
