1 Structural Geology Lab – Week 1 Attitudes of Lines and Planes in 3-D Read and Complete Lab 1 in the Rowland and Dubendorfer Manual. The following are basic notes to accompany the lab. Use the Math/Trigonometry Review sheets to help you in your solutions. I. Basic Orientation of Lines and Planes in Structural Geology A. Orientation of plane in space 1. Attitude: orientation of structural element in space a. planes: strike and dip b. lines: trend and plunge 2. Bearing: compass direction orienting line in space relative to horizontal plane a. Azimuth vs. Quadrant 3. Strike: compass bearing of horizontal line on a plane, formed by line of intersection between horizontal plane and inclined plane. a. infinite no. of parallel strike lines for any inclined plane b. data representation: azimuth direction 4. Dip: vertical angle between inclined plane and horizontal plane measured perpendicular to strike direction a. data: angle + direction of down dip orientation (1) (i.e. direction water would run down the plane)
