Minnesota strike and dip data

3,696 structural measurements in Minnesota, digitized from 53 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 Minnesota holds:

Measurement typeGeometryMeasurementsShare
Foliation Planar — strike and dip 1,28735%
Other Planar — strike and dip 1,04428%
Bedding Planar — strike and dip 61017%
Lineation (mineral, stretching) Linear — trend and plunge 39811%
Joint Planar — strike and dip 2096%
Fold hinge / axis Linear — trend and plunge 752%
Vein / dike Planar — strike and dip 592%
Fault plane Planar — strike and dip 12<1%
Slickenline 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.
