Page 1 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

1. What is the significance of the concept of \principal stress\? 2. Sketch a 2D stress ellipse for the case 01=5GPa and 02= 2GPa where 01 is vertical

November 1, 2000 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

September 8, 2000 1. Describe the difference between slip and separation on a fault. 2. What type of offset() can be interpreted from the map below? Give a detailed description of your logic on the back of the page

September 1, 2000 1. The following map shows the principal azimuths for fractures measured on the Brokenback feature in Wyoming. Interpret the fracture pattern using your knowledge of joints and joint systems Prepare a written (1 paragraph)analysis

1. Interpret the geologic history of the grand Canyon using the diagram below. List the events in order from the oldest(at the bottom of the page) to the youngest( the top of the page). For each event describe the principle or observation you used
