Thorsten W. Becker Jackson School of Geosciences The University of Texas at Austin Global plate tectonic maps

These maps are produced with GMT, iGMT, and make use of a range of geophysical datasets as compiled within iGMT or the Unified Geodynamics Earth Science Computing Environment (UGESCE), and may be useful for teaching or research. For information on how to make such maps and use GMT and iGMT, see my computing and Earth science mapping teaching material and the Unified Geodynamics Earth Science Computing Environment (UGESCE).

   The iGMT produced GMT scripts used to make these maps can be found by following this link to the data ftp directory.

   You might also want to check out a comparison of all the colormaps that come with GMT, as PDF files in their in their original spacing, or normalized to 0...1.
   
   

4. Topography, plate boundaries, and subduction zone seismicity contour map:

   This map can be useful to find rough geographic locations, etc. Slab contours are from Gudmundsson & Sambridge's (1998) RUM model.
