Arkansas strike and dip data

5,384 structural measurements in Arkansas, digitized from 42 published geologic maps across 3 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 Arkansas holds:

Measurement typeGeometryMeasurementsShare
Bedding Planar — strike and dip 4,68587%
Other Planar — strike and dip 67613%
Vein / dike Planar — strike and dip 19<1%
Lineation (mineral, stretching) Linear — trend and plunge 3<1%
Fault plane Planar — strike and dip 1<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.
