Overview of the Geology of Cuba
Chapter 2 Overview of the Geology of Cuba Abstract The Cuban Orogen can be divided into two major structural and strati- graphic units: basement and cover. The basement is the mega complex of igneous, metamorphic, and sedimentary rocks that lies below the little deformed section of the cover. It is divided into several tectonic large units, according to its structural style and age of the rocks. We can distinguish three large complexes: (a) Proterozoic basement, (b) Mesozoic basement, and (c) Paleogene folded belt. The Proterozoic basement outcrops in very limited areas and its structure is unclear. The Mesozoic basement consists of four complexes of very different nature: the Mesozoic paleomargin of the SE North American plate, containing Jurassic-Cretaceous sequences with varying degrees of deformation; the remaining three units, the ophiolite association, successions of volcanic arcs, and southern metamorphic terrains, have traits of tectono stratigraphic terrains. The links between the four major structures of the Paleogene deformed belt are much clearer. However the outstanding deformations and horizontal transport suffered by some units, the primary spatial relationships (paleogeographic) between them are essentially pre- served. At the Paleogene folded and faulted belt are distinguished: • Foreland basin successions. • Piggyback basins successions. • Sierra Maestra-Cresta Caimán vol- canic arc. • Synorogenic basin of Middle and Upper Eocene S Eastern Cuba. The cover composed of deposits from Lower or Middle Eocene to Quaternary, com- prises the younger deposits of the section, little deformed in relation to the underlying layers, usually separated from these by remarkable structural discor- dance. Throughout Cuba, the cover is completely devoid of evidences of magmatic, metamorphic, and hydrothermal activity. -

Portrait of Mary Anning, in oils, probably painted by William Gray in February, 1842, for exhibition at the Royal Academy, but rejected. The portrait includes the fossil cliffs of Lyme Bay in the background. Mary is pointing at an ammonite, with her companion Tray dutifully curled beside the ammonite protecting the find. The portrait eventually became the property of Joseph, Mary‟s brother, and in 1935, was presented to the Geology Department, British Museum, by Mary‟s great-great niece Annette Anning (1876-1938). The portrait is now in the Earth Sciences Library, British Museum of Natural History. A similar portrait in pastels by B.J.M. Donne, hangs in the entry hall of the Geological Society of London. -

Newsletter 2017-18 Department of GEOSCIENCES From the Department Head Hi alums: I hope this newsletter finds you in good health and spirits. It’s been a very exciting and productive year in the department. In case the news hasn’t reached you, Lee Kump was recently named the seventeenth dean of the College of Earth and Mineral Sciences. We are incredibly proud of Lee for this major honor and we know that the college will benefit greatly under his dedicated and sage leadership. Lee’s vision and energy has left the department a much better place. I’m sure all of the faculty will join me in thanking him for a job very well done. I’ve just re-stepped into the headship for a year as we conduct a national search for a new leader. Lee plans to keep an active research program, but it’s still a bittersweet time for many of us with the retirements of Mike Arthur and Terry Engelder, although we expect both of them to be in the department regularly. You can read more about Mike’s and Terry’s incredible careers in this issue, but needless to say we are going to miss these inspirational scientists. Mike “Black Shale” Arthur wrote the textbook on how ancient organic-rich rocks accumulated, and christened the field of chemostratigraphy. Terry “Marcellus” Engelder had one of the most productive late careers on record with his discovery of fracturing patterns in the Marcellus Shale that helped pave the way for gas production in our state. It’s been fun to watch the career paths of these two very different scientists converge in recent years. -

The Geology of Habana, Cuba, and Vicinity
THE GEOLOGY OF HABANA, CUBA, AND VICINITY ROBERT H. PALMER Habana, Cuba ABSTRACT Habana is located on the western end of an anticlinorium that extends from Habana to Matanzas, a distance of approximately 1oo kilometers. The structure is complicated by minor folds and east of Habana Bay by intrusions. The column consists of Upper Cretaceous, Eocene, Oligocene with two members, undifferentiated Upper Tertiary, and Pleistocene or Recent. The Cretaceous is exposed in a belt o10kilometers wide along the axis of the anti- clinorium, and is flanked by the Tertiary on the north, west, and south sides. The low-dipping Tertiary lying unconformably on the steeply dipping Cretaceous evidences extensive post-Cretaceous-pre-Upper Eocene folding and erosion. Since Eocene time the principal events have been elevations and submergences with one minor period of folding. Habana Bay is a drowned valley in the Cretaceous connected with the ocean by a channel through faulted Tertiary limestone. The first knowledge of the geology of Habana was recorded by Humboldt' who visited Cuba in 1803 and again in i805. His obser- vations are general but valuable. He recognized the continuity of an extensive formation in various parts of the island which later writers have denominated "CavernousLimestone," "Porous Lime- stone" and "Yumuri Limestone." To this widespread series Hum- boldt gave the name "Giiines Limestone" from its occurrence north of Gtiines in Habana Province. Arguing solely from lithologic simi- larity, Humboldt believed this formation to be Jurassic and not Tertiary in age as it now has been found to be. He also recordedthe presenceof serpentineat Guanabacoa.
