Most bulk elastic media are weakly anisotropic. The equations governing weak anisotropy are much simpler than those governing strong anisotropy, and they are much easier to grasp intuitively. These equations indi­ cate that a certain anisotropic parameter (denoted 8) controls most anisotropic phenomena of importance in exploration geophysics, some of which are nonnegligible even when the anisotropy is weak. The critical parame­ ter 8 is an awkward combination of elastic parameters, a combination which is totally independent of horizon­ tal velocity and which may be either positive or nega­ tive in natural contexts.
