Geologic map

On a geologic map, this is represented with a short straight line segment oriented parallel to the strike line.
Bedding planes and structural features such as faults, folds, are shown with strike and dip or trend and plunge symbols which give three-dimensional orientations features.

Orientation (geometry)

orientationattitudespatial orientation
Strike and dip refer to the orientation or attitude of a geologic feature.
More specialist uses include Miller indices in crystallography, strike and dip in geology and grade on maps and signs.

Inclinometer

Strike and dip are determined in the field with a compass and clinometer or a combination of the two, such as a Brunton compass named after D.W. Brunton, a Colorado miner.
In prospecting for minerals, clinometers are used to measure the strike and dip of geologic formations.

Cuesta

This includes sedimentary bedding, faults and fractures, cuestas, igneous dikes and sills, metamorphic foliation and any other planar feature in the Earth.
This results in a long and gentle backslope called a dip slope that conforms with the dip of resistant strata, called caprock.

Brunton compass

Strike and dip are determined in the field with a compass and clinometer or a combination of the two, such as a Brunton compass named after D.W. Brunton, a Colorado miner.
Arguably the most frequent use for the Brunton in the field is the calculation of the strike and dip of geological features (faults, contacts, foliation, sedimentary strata, etc.).

Fault (geology)

faultfaultsstrike-slip
This includes sedimentary bedding, faults and fractures, cuestas, igneous dikes and sills, metamorphic foliation and any other planar feature in the Earth.
The dip of a reverse fault is relatively steep, greater than 45°.

Dip slope

A dip slope is a topographic (geomorphic) surface which slopes in the same direction, and often by the same amount, as the true dip or apparent dip of the underlying strata.

Geology

Strike and dip refer to the orientation or attitude of a geologic feature.

Bed (geology)

beddingbedsbedding plane
The strike line of a bed, fault, or other planar feature, is a line representing the intersection of that feature with a horizontal plane.

Azimuth

azimuthalazimuthal angleazimuth angle
Strike (or strike angle) can be given as either a quadrant compass bearing of the strike line (N25°E for example) or in terms of east or west of true north or south, a single three digit number representing the azimuth, where the lower number is usually given (where the example of N25°E would simply be 025), or the azimuth number followed by the degree sign (example of N25°E would be 025°).

Geology of the Pyrenees

Pyrenean orogenyPyreneesPyrenean orogenies
The Pyrenees are a 430-kilometre-long, roughly east–west striking, intracontinental mountain chain that divide France, Spain, and Andorra.

Michigan Basin

Michigan
The feature is represented by a nearly circular pattern of geologic sedimentary strata in the area with a nearly uniform structural dip toward the center of the peninsula.

Bonndorf Graben

The Bonndorf Graben (Bonndorfer Graben) is a southeast-northwest to east-west striking, tectonic graben system on the eastern edge of the Black Forest and in the Baar between Bonndorf im Schwarzwald (in the south) and Donaueschingen (in the north).

Angle of repose

the maximum possible sand slopeCritical angle of reposean engineering term
The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping.
