Abstract

These data are supplementary material to "3D Modelling of Vertical Gravity Gradients and the delimitation of tectonic boundaries: The Caribbean oceanic domain as a case study" (Gómez-García et al., 2019).

This dataset contains information about the structure of the Caribbean oceanic crust, based on the modelling of the Vertical Gravity Gradients, which are gravity derivatives especially sensitive to density contrasts in the upper layers of the Earth.

The files included are:
1) The inferred densities of the Caribbean crystalline crust, in the file “CrustalDensities.txt”.
2) The residuals of the Vertical Gravity Gradients (VGG), in the file “ResidualsVGG.txt”, which were used to define the terrain boundaries.
3) A collection of shapefiles (2019GC008340_Gdb.gdb) with the main inferred tectonic/terrain boundaries and additional geologic features.
4) A "Read me" file with the description of the different shapefiles available in the geodatabase.
