Kinematic reconstruction of the Caribbean region since the Early Jurassic

The geochemistry of the Maimón Formation (Central Cordillera, Dominican Republic) revisited

“…Este último cinturón está constituido por fragmentos acrecionados de: arcos vulcano-plutónicos, litosfera oceá-nica ("ofiolitas") del Caribe (Pacífico) y Proto-Caribe (Atlántico), canales de subducción, cuencas de trinchera, materiales de retro-arco y ante-arco, y de los márgenes continentales de Norteamérica y Suramérica así como bloques continentales menores como Maya y Chortís (e.g. Pindell et al, 2005Pindell et al, , 2006Iturralde-Vinent et al, 2008;Pindell y Kennan, 2009;Boschman et al, 2014).…”

“…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). Esta corteza oceánica está compuesta mayoritariamente por basaltos con afinidades MOR (mid-ocean ridge; Donnelly, 1994).…”

Mineralogy, geochemistry and sulfur isotope characterization of Cerro de Maimón (Dominican Republic), San Fernando and Antonio (Cuba) lower Cretaceous VMS deposits: Formation during subduction initiation of the proto-Caribbean lithosphere within a fore-arc

“…135 Ma (Rojas-Agramonte et al, 2011;Pindell et al, 2012, and references therein). Subduction and related arc magmatism ceased in Hispaniola and Cuba in the latest Cretaceous-earliest Tertiary as a result of volcanic arc-Caribeana terrane collision (García-Casco et al, 2008), though subduction and volcanism renewed in Hispaniola and eastern Cuba until the Eocene when the final collision of the arc and the Bahamas Platform took place (Lewis and A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT Draper, 1990;Mann et al, 1991;Rojas-Agramonte et al, 2006, 2008Boschman et al, 2014).

U-Pb LA-ICP-MS GEOCHRONOLOGY AND GEOCHEMISTRY OF JURASSIC VOLCANIC AND PLUTONIC ROCKS FROM THE PUTUMAYO REGION (SOUTHERN COLOMBIA): TECTONIC SETTING AND REGIONAL CORRELATIONS

“…Regional paleogeographic models, stratigraphic considerations or scarce geochemical data have been commonly used to propose two different tectonic environments: (1) a continental volcanic arc related with the Pacific subduction (Boschman, et al, 2014;Bustamante et al, 2010;McCourt et al, 1984;Meschede and Frisch, 1998;Pindell and Tabbutt, 1995;Pindell and Erikson, 1993;Spikings et al, 2014;Toussaint, 1995), (2) an intracontinental extensional rifting that can be associated to the breakup of Pangea in the Triassic and Early Jurassic (Cediel et al, 2003;Cochrane et al, 2014;Pindell and Dewey, 1982;Ross and Scotese, 1988).…”
