Tennessee strike and dip data

6,502 structural measurements in Tennessee, digitized from 154 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 Tennessee holds:

Measurement typeGeometryMeasurementsShare
Bedding Planar — strike and dip 5,29081%
Other Planar — strike and dip 62610%
Cleavage Planar — strike and dip 3906%
Vein / dike Planar — strike and dip 1262%
Fold hinge / axis Linear — trend and plunge 53<1%
Joint Planar — strike and dip 11<1%
Foliation Planar — strike and dip 4<1%
Lineation (mineral, stretching) Linear — trend and plunge 2<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.
