Smear-gouge ratio is the ratio of sand to shale that has moved past some critical portion of the fault plane.[1] Although not simply relatable to the shale gouge ratio, the smear gouge ratio varies in an inverse manner; i.e., high shale gouge ratio corresponds to low smear gouge ratio and vice versa.
Both ratios are commonly called SGR.
