Georgia strike and dip data

1,780 structural measurements in Georgia, digitized from 14 published geologic maps across 2 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 Georgia holds:

Measurement typeGeometryMeasurementsShare
Foliation Planar — strike and dip 78044%
Bedding Planar — strike and dip 76543%
Lineation (mineral, stretching) Linear — trend and plunge 1659%
Fold hinge / axis Linear — trend and plunge 463%
Vein / dike Planar — strike and dip 10<1%
Fault plane Planar — strike and dip 6<1%
Slickenline Linear — trend and plunge 6<1%
Joint Planar — strike and dip 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.
