The production of a Structural Map of the Caribbean was launched at the General Assembly of the CCMG in 2004 (resol. 65) - following a feasibility meeting held in the Caribbean, in Guadeloupe (18 and 19 November 2004) - to fill the gap in the CCMG maps between the South American and North American continents and to highlight the main geological features of the plates interacting with the Caribbean plate. A relevant representation was designed using a dual approach for onshore and offshore.

A compilation of geological data from national maps and academic articles has been carefully carried out in large regions (see overlapping boxes in insert) of the map, while retaining its specificity.

The legend is supported by an outline of the chronology of the formations in each major region, represented in the form of columns arranged according to stratigraphic scale. As the offshore area has been explored unevenly, the approach was different and based mainly on geophysical data to which were added the geological characteristics deduced from seismic or bathymetry.

The geophysical data (marine magnetic anomalies) were recompiled and fully reprocessed (García-Reyes, 2018; 2021). We interpreted the crustal nature of the Caribbean Plate and the Gulf of Mexico from the recompiled marine magnetic anomalies and the vertical gravity gradient (Sandwell et al., 2014). A correlation between offshore and onshore data was attempted.
