Structural Geology: Stereonet: Apparent Dip: Example 2.1

Example 2.1 Plane: 020 35 SE Direction of apparent dip: 070 How to determine apparent dip of a plane given its strike and true dip and a direction of interest (direction of apparent dip), using a stereonet (Schmidt, equal-area net). Hemisphere model is used at 06:40. This video employs what I refer to as the “American right-arm rule” for strike and dip of planes; looking to the strike direction, the plane dips in the direction of the observer’s right arm. This is very different from the traditional “British right-hand rule”. This video was produced during the fall of 2020, at the heart of COVID, as part of my effort to teach structural geology online.
