Structural Measurement Atlas
Atlas / States / Kentucky

Kentucky strike and dip data

2,993 structural measurements in Kentucky, digitized from 68 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 Kentucky holds:

Measurement typeGeometryMeasurementsShare
Joint Planar — strike and dip 2,04868%
Bedding Planar — strike and dip 83728%
Other Planar — strike and dip 542%
Vein / dike Planar — strike and dip 462%
Fault plane Planar — strike and dip 8<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.
