“…2 and 3C;Iturralde-Vinent, 1996). The available petrological, geochemical, and geochronological data suggest that Cuban ophiolites include both mid-ocean-ridge and supra-subduction zone types (Kerr et al, 1999;Proenza et al, 2006;Marchesi et al, 2007;Lázaro et al, 2015). However, the widespread occurrence in the ophiolites of very refractory mantle peridotites as well as extrusive rocks with geochemical characteristics of island arcs indicate that the protoliths of most Cuban ophiolites formed above a subduction zone by both fore-arc and back-arc spreading.…”

Cuba is the largest island in the Greater Antilles, and its geology records three important episodes: (1) the Jurassic breakup of North and South America (Pangea) and associated passive margin and oceanic sedimentary and magmatic evolution; (2) the sedimentary, magmatic, and metamorphic evolution of an intra-oceanic Cretaceous-Paleogene ophiolite-arc complex; and (3) the Paleogene "soft collision" and transfer of the NW Caribbean plate (and Cuba) to the North American plate. Thick sequences of JurassicCretaceous strata (conglomerates, sandstones, limestones, dolostones, shales) and interlayered basaltic rocks characterize passive margin sequences preserved in the Guaniguanico terrane (western Cuba, related to the Mayan passive margin and the Gulf of Mexico) and the Bahamas Platform borderlands (north of Cuba). Passive margin deposition ceased in latest Cretaceous time, when increasing relief of accreted (overriding) oceanic arc and ophiolite complexes shed coarse sediments (olistostrome and flysch), followed by carbonate deposition. Fragments of the intervening oceanic lithosphere (Proto-Caribbean, connected to the Central Atlantic) and fore-and back-arc oceanic lithosphere (Caribbean, of Pacific origin) occur as tectonic fragments detached from the ophiolitic units, including serpentinized harzburgites and dunites, banded and isotropic gabbros, basalts (tholeiitic and fore-arc basalts, locally with boninites) and Late Jurassic (Tithonian) through Late Cretaceous (Coniacian and younger) oceanic sediments. Arc activity in the Cuban segment of the Greater Antilles produced sedimentary, volcanic, and plutonic rocks during Cretaceous times (ca. 135-70 Ma). A new arc developed in eastern Cuba during Paleocene-middle Eocene times. Cuban arc sequences include island-arc tholeiitic, calcalkaline, and alkaline bimodal suites of volcanic and plutonic rocks. Remnants of ProtoCaribbean oceanic lithosphere occur as exhumed mélange-bearing eclogite-, blueschist-, and garnet-amphibolite-facies tectonic blocks (oldest age ca. 120 Ma) within a serpentinite matrix intercalated with, or at the base of, the overthrusted ophiolitic bodies. Cuban Cretaceous arc magmatic activity ended due The geology of Cuba: A brief overview and synthesis to the subduction of Proto-Caribbean passive margin sequences of the Caribeana terrane, an offshore protuberance of Yucatan. This event formed strongly deformed high-pressure metasedimentary and metaigneous rocks at ca. 70 Ma, when the Caribbean plate began to collide with North America. The collision, which included overriding of the ophiolitic and arc units over both subducted and unsubducted passive margin sequences, also produced synorogenic basins and filled them, a process that continued until ca. 40 Ma. This foldbelt was succeeded by local uplift and subsidence to form late Eocene-Recent unconformable post-orogenic continental basins.

“…El arco-isla de las Antillas Mayores contiene un amplio registro de volcanismo asociado a subducción que, prolongándose durante más de 70 Ma, abarca términos boniníticos y toleíticos de arco (IAT) del Cretácico Inferior en gradación general hasta series calco-alcalinas ricas en K del Cretácico Superior (Donnelly y Rogers, 1980;Donnelly et al, 1990;Lebron y Perfit, 1994;Kerr et al, 1999;Jolly et al, 2001), si bien existen toleítas de arco del Cretácico Superior (e.g. Proenza et al, 2006;Marchesi et al, 2007). Existe un amplio consenso en que, precediendo la subducción, la formación de la litosfera oceáni-ca del Proto-Caribe (brazo Caribeño del Atlántico Central) tuvo lugar a partir de rifting continental de edad Jurásico Medio/Superior y sucesiva apertura Cretácica de una cuenca oceánica entre los continentes de Norte y Suramérica tras la ruptura de Pangea (Pindell y Barret, 1990;Meschede y Frisch, 1998;Mann, 1999;Boschman et al, 2014).…”

“…En cambio, la polaridad inicial de la subducción, la existencia de un cambio de polaridad a lo largo del Cretácico o de un único o múl-tiples arcos siguen siendo objeto de recurrente discusión (e.g. Kerr et al, 1999;Iturralde-Vinent, 2003;Proenza et al, 2006;Marchesi et al, 2007;Pindell et al, 2012;Escuder-Viruete et al, 2014;Lázaro et al, 2014). Los primeros modelos evolutivos del Caribe que abrazaron las ideas de la tectónica de placas en los años 1970'-80' (Bracey y Vogt, 1970;Malfait y Dinkelman, 1972;IturraldeVinent, 1975;Ladd, 1976;Mattson, 1979;Maurrasse, 1981;Pindell y Dewey, 1982;Walper, 1982) fueron recogidos, complementados y discutidos posteriormente por Draper y Lewis (1989), Donnelly et al (1990), Lewis y Draper (1990) y Pindell y Barret (1990.…”

“…Si bien es cierto que en las Antillas Mayores las rocas del PIA-IAT preceden a las CA, la transición de unas a otras aparentemente se prolongó desde el Barremiense hasta el Turoniense (ca. 130-90 Ma; Proenza et al, 2006;Marchesi et al, 2007;Hastie et al, 2009;Pindell et al, 2012). Por otro lado, proponen que la subducción-acreción durante el Campaniense tardío -Paleoceno temprano de secuencias sedimentarias de margen pasivo de afinidad Proto-Caribeña (Atlántica; a las que agrupan bajo el nombre de Caribeana) desencadenó una interrupción o atenuación en el volcanismo de arco y un cambio en el ángulo de la subducción con especial afectación al O del arco (Cuba central y occidental).…”

RESUMENLos materiales volcánicos de la Formación Maimón, metamorfizados en facies de esquistos verdes, son representativos del magmatismo más antiguo registrado en el arco-isla del Cretácico del Caribe. A partir de nuevos datos geoquímicos de roca total y mediante el uso de elementos traza inmóviles (elementos de alto potencial iónico -HFSE, tierras raras -REE), se reconoce el predominio de protolitos basálticos y una menor proporción de rocas de composición intermedia y ácida. Geoquímicamente, los protolitos basálticos han sido clasificados como boninitas, toleítas de arco de isla pobres en Ti y LREE, toleítas de arco de isla pobres en Ti normales y escasas toleítas de arco de isla normales. Las rocas ácidas presentan claras afinidades boniníti-cas y toleíticas y pertenecerían al tipo M (derivadas del manto). La geoquímica de las toleítas pobres en Ti y LREE permite su clasificación como FAB (Fore-Arc Basalts, i.e. basaltos de ante-arco), término recientemente acuñado para describir toleítas con rasgos de MORB (basaltos de dorsal centro-oceánica) identificados en el ante-arco de Izu-Bonin-Mariana. La presencia de FAB y su correlación estratigráfica con boninitas son indicativas de formación en un contexto de ante-arco durante los primeros estadios magmáticos en un régimen extensional ligado al inicio de la subducción y el nacimiento del arco-isla. La Fm. Maimón puede representar la sección superior (volcánica) de una ofiolita tipo "inicio de subducción" .
