202067Structural geology is the study of the threedimensional distribution of rock units with respect to their deformational histories. The primary goal of structural geology is to use measurements of presentday rock geometries to uncover information about the history of deformation in the rocks, and ultimately, to understand the stress field that resulted in the observed strain and geometries.
