Wyoming strike and dip data

18,214 structural measurements in Wyoming, digitized from 169 published geologic maps across 5 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 Wyoming holds:

Measurement typeGeometryMeasurementsShare
Foliation Planar — strike and dip 9,77354%
Bedding Planar — strike and dip 6,12734%
Lineation (mineral, stretching) Linear — trend and plunge 9995%
Other Planar — strike and dip 8174%
Fold hinge / axis Linear — trend and plunge 2051%
Vein / dike Planar — strike and dip 162<1%
Joint Planar — strike and dip 122<1%
Fault plane Planar — strike and dip 9<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.
