The mechanical parameters of a rock fracture are dependent on its surface roughness anisotropy. In this Letter, we show how quantitatively describe the anisotropy of a rock fracture surface. A parameter, referred to as the index for the accumulation power spectral. density psd*, is proposed to characterize the anisotropy of a rock fracture surface. Variation of psd*, with orientation angle theta of sampling, is also discussed.
