Geological Society of America. 

Structural geology and tectonics are the investigation of the geometry, kinematics, and dynamics of deformation in natural materials at all scales. These investigations are frequently field-based and draw on remote observations, experimental work, and computer simulations. They are commonly interdisciplinary, involving other geoscientists, scientists and society members. The investigations increase the basic understanding of geological processes, hazards, and resources, thus contributing to the well being of society.

The purpose of the division is to bring together scientists interested in structural geology and tectonics to facilitate the presentation and discussion of their problems and ideas, to stimulate communication with other earth scientists, to promote research and the publication of results on structural geology and tectonic studies, and to advise and assist the officers and committees of the Society in matters pertaining to structural geology and tectonics.
