Structural Geology- Introduction Introduction Structural geology is the study of deformed rocks, and rock deformation. In structural geology, we are faced with a series of natural features that we try to interpret and explain. Each of these features formed through the interplay of external forces on rock materials, and the \local \conditions at the time of deformation. To interpret structures in the natural setting we need to

1. Draw a 2 dimensional Mohr Circle representation for the following stress conditions

Complete the block diagrams for the following features. Be sure to include the appropriate map symbols on your drawings. Inclined anticline with hinge surface

Brokenback feature in Wyoming. Interpret the fracture pattern using your o 1. The following map shows the principal azimuths for fractures measured on th knowledge of joints and joint systems. Prepare a written(1 paragraph) analysis detailing the \joint system\these fractures may represent. Be sure to include a discussion of your evidence in support of your conclusion
