TLDR
GMT allows users to manipulate (x,y,z) data, and generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, and/or shaded-relief plots using a variety of map projections.Abstract:
Version 31 of the Generic Mapping Tools (GMT) has been released More than 6000 scientists worldwide are currently using this free, public domain collection of UNIX tools that contains programs serving a variety of research functions GMT allows users to manipulate (x,y) and (x,y,z) data, and generate PostScript illustrations, including simple x-y diagrams, contour maps, color images, and artificially illuminated, perspective, and/or shaded-relief plots using a variety of map projections (see Wessel and Smith [1991] and Wessel and Smith [1995], for details) GMT has been installed under UNIX on most types of workstations and both IBM-compatible and Macintosh personal computersread more

Lithospheric structures and Precambrian terrane boundaries in northeastern Botswana revealed through magnetotelluric profiling as part of the Southern African Magnetotelluric Experiment
TL;DR: In this article, a focused study was undertaken to gain improved knowledge of the lithospheric geometries and structures of the westerly extension of the Zimbabwe craton (ZIM) into Botswana, with the overarching aim of increasing our understanding of southern African tectonics.

Constraints on the deformation and rupturing of continental lithosphere of the Red Sea: the transition from rifting to drifting
J. R. Cochran,Garry D. Karner +1 more
TL;DR: In the case of the northern Red Sea, the authors of as mentioned in this paper have shown that the seafloor spreading in the Red Sea is not organized, although individual volcanoes are located within discrete ‘deeps’ spaced along the axial depression.

Electromagnetic images of the Trans-Hudson orogen: the North American Central Plains anomaly revealed
TL;DR: The NACP anomaly is remarkable in its continuity along strike, testimony to along-strike similarity of orogenic processes as discussed by the authors, where bedrock is exposed, the anomaly can be associated with sulphides that were metamorphosed during subduction and compression and penetratively emplaced deep within the crust of the internides of the orogen to the boundary of the Hearne margin.

The enigmatic Chad lineament revisited with global gravity and gravity-gradient fields
TL;DR: In this paper, the Chad lineament, a 1300 km arcuate feature located between the west and central African rift system, was studied and it was shown that along the centre of the lineament high-density rocks must be present, which relate to either magmatic or metamorphic rocks.
