A background in structural-metamorphic history and shear zones in the Archean Block of Greenland and the Dalradian of northeast Scotland sparked my interest in the often-conspicuous, late-stage vein systems that are present in these regions. Recognizing that vein geometries are commonly similar looking, independent of the scale of observation, I was also aware of fractal phenomena increasingly being reported in the Earth Science literature, and I began some quantitative studies of vein systems. Brittle fractures also display fractal relationships, and the prospect of using microstructures to predict properties of macrofractures forms the central concept of my work. Applications of this work are particularly relevant in the characterization of fractured hydrocarbon reservoirs.
