a map that portrays the structure of the earth’s crust and, usually, reflects the primary phases in development of the crust within particular regions or for the earth as a whole. Such maps are made on the basis of geologic maps through the use of geophysical and other data. ...
Its relief map illustrates linear features reflecting fault scarps, step-overs, pull-apart areas and bends associated with tectonic deformation. A harmonized geological map of the study area that was continuous over the cross-border areas was compiled. The map reveals lithologies, ages of formations...

The 2006U.S. Geological Surveymap of tectonic plates show 21 of the major plates, as well as their movements and boundaries. Convergent (colliding) boundaries are shown as a black line with teeth, divergent (spreading) boundaries as solid red lines, and transform (sliding alongside) boundaries ...

The first drift stage has sedimentation confined to the continental slope due to the uplift of the shelf region, whereas during the second drift stage sedimentation surpasses the border fault and the sedimentary succession overlies directly the rift supersequence. A structural fault map was built, ...
Left image is area before mapping, right image is area after mapping; black lines show the identified faults. Background Image credit: Esri, Caltech Murray Lab, NASA, JPL, MSSS. (c) FracPaQ generated fault intensity map of mapped faults. 3.1.1 Fault Groups The initial approach of ...
Map of the Earth showing the relation between fault lines (blue) and zones of volcanic activity (red). Credit: zmescience.com Earthquakes: Scientists have known for some time that the majority of the seismic activity occurs along plate boundaries. Hence why roughly 90% of the world’s earthq...
The map is in the Swiss coordinate system CH1903 slickenlines (or slip direction) and surfaces on which they occur. The slickenline rake is the angle measured clock- wise between the strike direction and the slickenline on the surface of interest. We discriminated several groups of faults ...
