Structural Measurement Atlas
Atlas / States / Alabama

Alabama strike and dip data

1,678 structural measurements in Alabama, digitized from 89 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 Alabama holds:

Measurement typeGeometryMeasurementsShare
Bedding Planar — strike and dip 1,59495%
Vein / dike Planar — strike and dip 835%
Lineation (mineral, stretching) Linear — trend and plunge 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.
