The evolution of geological cartography in Cuba in its more than
135 years of history has been possible through the consultation of
numerous archival reports, publications, maps and personal
interviews with different authors and geologists of vast
experience. A brief critical analysis is made of the increase in
the degree of geological knowledge of the country since the
elaboration of the Geological Sketch of the Cuban Island at a scale
of 1: 2 000 000 (Fernandez de Castro, 1883), first of Cuba and of
Ibero-America, until the most recent Digital Geological Map of Cuba
at scale 1: 100 000 (Perez Aragon, 2016). Cuba and its surroundings
are a geological mosaic in the southeast corner of the North
American plate with rocks from many different origins, from
Proterozoic to Quaternary, extended along the southern border of
the plate. From the Eocene, this belt has been dissected by several
great faults, related to the development of some great oceanic
depressions (Cayman trough and Yucatan basin). The fossil record of
Cuba, which covers approximately the last 200 million years of life
on Earth, is rich in very varied fossils, witnessing a wide
diversity of organisms, both animals and plants, that inhabited the
Antillean and Caribbean region; and that constitute the inheritance
of the biological diversity that the current Cuban archipelago
exhibits. As a result of the preparation of the Cuban Metallogenic
Map at scale 1: 250 000, forty-one models and eight sub-models of
metallic mineral deposits were identified. These models, of
descriptive-genetic type, together with the analysis of their
spatial distribution and their relationship with geology, allowed
the identification and mapping of ten mineral systems, linked to
the geodynamic environments present in the Cuban territory. Cuba
has large deposits of limestone, loam, dolomite, kaolin, gypsum and
anhydrite, rock salt, marbles, sands and clays of different types,
zeolites, peat, therapeutic peloids and many more. There are
manifestations of decorative and precious rocks such as jasper,
jadeite, different varieties of quartz and even xylopals. A
compilation of geochemical data of oceanic basalt samples from
previous works, together with data of analyzed samples during this
study in order to discuss geochemical criteria based on immobile
element (proxies for fractionation indices, alkalinity, mantle flow
and subduction addition), provide a comprehensive ophiolite
classification according to their tectonic setting. This book
addresses different facets of the geological knowledge of Cuba:
history of its cartography, marine geology, fossil record,
stratigraphy, tectonics, classification of its ophiolites,
quaternary deposits, metallogeny and minerageny.
