Searching I stumbled over this paper[1], which I found interesting, on characterizing the fractal-ness of geological structures.

They point out that the usual measure of fractal dimension, or capacity dimension[2], doesn't consider the physical size of the features and can thus be inaccurate. Instead they suggest using the information dimension[3], which is bounded by the capacity dimension.

Seems there are a few more, Higuchi Dimension, Box Counting Dimension (D0), Generalized Rényi Dimension and others are discussed mid-way through this;
