Geology of Cuba

For many years the geology of Cuba has been a challenge to every geologist who has come in contact with any of its aspects, and many were attracted by some of the exceptional features of the island, for example, the extensive development of ultrabasic rocks; the numerous oil and gas seeps; the rich Jurassic ammonite faunas, the variety of its Tertiary foraminifera, and the presence of some of the largest Upper Cretaceous rudistids ever discovered, to name only a few. The greatest geological attraction of the island, however, has been the challenge of understanding the stratigraphy and the structures, not to mention the difficulty of reconstructing the geologic history in a logical and probable way.
