# Measure the relative size or height of the fractures, paying particular attention to any rock features that tend to control the vertical extent of the fractures, such as lithology breaks, bedding planes, stylolites, or [[Unconformity|unconformities]].

# Observe the width and width variation of the fractures. Measurements of width could be made with a scale, [http://www.merriam-webster.com/dictionary/micrometer micrometer], or caliper or by impregnation with epoxy or plastic for either thin section measurement of epoxy width or dissolution of matrix leaving the width at the depth approximated.<ref name=pt06r95 />
