Information provided
Petrofabrics is the study of deformation features in rocks, usually at the grain scale. The most commonly studied features are fractures (distribution, morphology, and orientation), twinning, pressure solution, and recrystallization fabrics.
Petrofabrics provides information on the following:
- Mechanisms of deformation
- Orientation and magnitude of principal stresses
- Deformation effects on porosity and permeability
How to use it
Structural petrofabric analysis is important in a relatively limited number of special situations. It requires oriented subsurface or surface samples and is performed only by a relatively limited number of specialists, usually at universities.
