Dip of strata
WebExercise 12.3 Putting Strike and Dip on a Map. This cross-section shows seven tilted sedimentary layers (a to g), a fault, and a steeply dipping dyke. Place strike and dip symbols on the map to indicate the orientations of the beds shown, the fault, and the dyke. Then answer the questions. 1.

Strike and dip is a measurement convention used to describe the plane orientation or attitude of a planar geologic feature. A feature's strike is the azimuth of an imagined horizontal line across the plane, and its dip is the angle of inclination (or depression angle) measured downward from … See more When measuring or describing the attitude of an inclined feature, two quantities are needed. The angle the slope descends, or dip, and the direction of descent, which can be represented by strike or dip direction. See more Conventions There are a few conventions geologists use when measuring a feature's azimuth. When using the strike, two directions can be measured at … See more On geologic maps, strike and dip can be represented by a T symbol with a number next to it. The longer line represents strike, and is in the same orientation as the strike angle. Dip is … See more • Compton, Robert R. (1985). Geology in the Field. New York: J. Wiley and Sons.

WebSedimentary strata often end up as inclined tabular planes, either through tectonic forces or, as in case of aeolian cross-strata, having been deposited that way. Dip, or dip angle, is the angle of the feature's incline from horizontal; so a horizontal surface would have a dip of 0°, a feature tilted downward 30° has a dip of 30°, and a ... WebNov 2, 2009 · The problem of the right-hand rules. by Jorge. When we want to record the orientation in space of a geological surface (e.g. a stratigraphic body), we have two different ways of doing it: a) Dip direction and dip angle: Dip direction is just the direction toward which the plane is inclined. Dip angle is the angle of inclination of the plane.
