Experiments in the theoretical mathematical investigation of stone erosion using many variables and statistical methods are described. Among the variables considered are acoustic wave velocity, air speed, air temperature, relative humidity of the air, precipitation, barometric pressure, duration of exposure, latitude, frequency of seismic oscillations, amplitude of seismic oscillations, duration of seismic events, elastic wave speed in the material, durationof erosion, material surface slope in relation to horizon, surface azimuth in relation to ground, yield stress of the material, ultimate resistance of the material, biological corrosion indices, chemical corrosion indices. -- AATA
