Structural Measurement Atlas
Atlas / States / Utah

Utah strike and dip data

9,668 structural measurements in Utah, digitized from 2,332 published geologic maps across 4 sources. Every row carries its azimuth, inclination, measurement type, location confidence and the citation of the map it came from.

What kinds of measurement

The Atlas separates planar structures, recorded as a strike and dip, from linear ones, recorded as a trend and plunge. This is what Utah holds:

Measurement typeGeometryMeasurementsShare
Bedding Planar — strike and dip 4,90251%
Vein / dike Planar — strike and dip 2,25523%
Joint Planar — strike and dip 1,94720%
Other Planar — strike and dip 3614%
Lineation (mineral, stretching) Linear — trend and plunge 80<1%
Foliation Planar — strike and dip 62<1%
Fold hinge / axis Linear — trend and plunge 39<1%
Fault plane Planar — strike and dip 22<1%

Where the data comes from

Each source is a survey, agency or program whose published mapping was harvested and reconciled into one schema. Rows are published only where the source's terms permit redistribution.
