“…Particular to western Cuba is the lack of the axis of the volcanic arc and the presence of mostly nonmetamorphic platform rocks in the Guaniguanico domain [Iturralde-Vinent, 1998], which is formed by the Sierra del Rosario and Los Organos belts (Figure 1). However, a narrow band of low-to very low grade metamorphic rocks with restricted development of high-pressure metamorphism known as the Cangre Belt crops out along the southern boundary of the Guaniguanico domain [Pszczolkowski, 1994a]. These rocks reach blueschist facies [Iturralde-Vinent, 1998] and their protoliths are rocks very similar to the oldest sediments of the Los Organos and Sierra del Rosario belts [Somin and Millan, 1972;Pszczolkowski, 1987].…”

“…[2] Several models have been proposed for the structural architecture and evolution of western Cuba: (1) those based on transpressional tectonics [Perez-Othon and Yarmoliuk, 1985;Millán, 2003] and (2) those based on thrust tectonics [Hatten, 1957;Cubapetróleo and Simon-Petroleum-Technology, 1993;Pszczolkowski, 1994a;Bralower and Iturralde-Vinent, 1997;Gordon et al, 1997;Iturralde-Vinent, 1998;Otero Marrero and Tenreyro Perez, 1998;Kerr et al, 1999;Moretti et al, 2003]. Transpressional models are strongly conditioned by the surficial expression of major left-lateral faults that can be identified throughout Cuba.…”

Structural and tectonic evolution of western Cuba fold and thrust belt

We present balanced and restored cross sections across the western Cuba fold and thrust belt to illustrate its structure and tectonic evolution, based on the interpretation of multichannel seismic profiles, field data and balancing techniques. The NNW–SSE trending Soroa cross section intersects, from south to north, (1) the Los Palacios Basin, (2) the Sierra del Rosario antiformal stack, (3) the Bahía Honda thrust unit, (4) the frontal ∼3‐km‐thick imbricated thrust sheets, and (5) the foredeep basin. At depth, a duplex that links the Sierra del Rosario unit and the frontal imbricates is defined using the thickness of the cover thrust sheets of the imbricated North American margin. The minimum calculated shortening is of 130 km in a SSE or south direction to fit large‐scale plate tectonic reconstructions. However, a more allochthonous alternative using thinner cover sequences is also discussed, which restores the Bahía Honda unit 220 km to the south of its present position. Syntectonic deposits in combination with a forward kinematic model provide a good constraint for the tectonic evolution of the orogen. The internally deformed Bahía Honda unit overthrusted the North America margin cover successions during Danian and Selandian times (∼65.5–60 Ma), before the stacking of these cover rocks during Selandian and Thanetian times (∼60–56 Ma). The growth of a large antiformal stack beneath the Sierra del Rosario occurred at early middle Eocene (∼56–45 Ma), generating about 4 km of structural relief between the paleoisland of Cuba and the synorogenic seafloor before the final infill of the foredeep.

“…This belt occupies an arcuate, topographically higher area across the north central part of the Sierra de Guaniguanico window (Figure 2b). A small segment of the northwestern part of this belt lies in fault contact with structurally higher ophiolites of the overlying Bahia Honda zone [Pszcz61kowski, 1994b] …”

“…The ophiolite-arc belt has been interpreted by most workers as a Cretaceous island arc that collided and overthrust partly coeval but distinctly different sedimentary facies of the passive margin that include carbonate, clastic, and evaporite rocks containing little or no arc detritus [Wassail, 1957;Pardo, 1975;Gealey, 1980]. At one locality in the thrust belt of north central Cuba, Renne et al [1989] The exposed passive margin sequence of North America in the Guaniguanico window of western Cuba has been subdivided by Pszcz61kowski [1987Pszcz61kowski [ , 1994a Pszcz61kowski [1985;1994a] with the chronology and style of tectonic phases presented in this paper. Note that our collisional and strike-slip phases that terminated passive margin subsidence are somewhat older than previous workers and that the post-strike-slip phases we propose were not recognized by previous workers.…”

“…The Pinos terrane is a medium pressure-medium temperature metamorphic sialic complex. The Guaniguanico terrane contains ophiolitebearing thrust-nappe sequences of Paleocene to early Eocene age (e.g., Cajalbana ophiolite: Pszczolkowski, 1994), and was strongly affected by Paleocene-middle Eocene strike-slip deformation during the opening of the Yucatan basin (Rosencrantz, 1990). The Guaniguanico terrane consists of several tectonic belts, one of which is the Rosario belt (Iturralde-Vinent, 1996).…”

The Cacarajicara Formation of western Cuba is a more than 700-m-thick calcareous clastic sequence that contains shocked quartz throughout, and spherules. Three members are recognized. The lower member consists of limestone and chert boulders, and disconformably overlies Cretaceous deep-water turbidite. It is characterized by: (1) a grain-supported fabric with only a small amount of matrix, (2) 5-15 cm, wellsorted clasts and occasional boulders, (3) reversely graded, discoidal or rectangular boulders showing a preferred orientation, (4) abundant shallow-and deep-water carbonate clasts in a well-mixed fabric, (5) direct contact between adjacent clasts, and (6) hydrostatic deformation within a black clay matrix. This evidence suggests that the lower member was deposited under conditions of high-density and high-speed laminar flow. The middle member consists of upward graded, massive to well-bedded, on June 3, 2015 specialpapers.gsapubs.org Downloaded from S. Kiyokawa et al. 126 homogeneous calcarenite. Unusual fluid-escape structures in the thick calcarenite suggest that this member formed by high-density turbidity suspension. The upper member consists of fine calcarenite mudstone; there is no evidence of bioturbation. We infer that it was deposited from a dilute, low-density suspension.On the basis of these criteria, the Cacarajicara Formation is interpreted to be a single hyperconcentrated flow that was formed by high-energy and high-speed concentrated flow. The south-southeast paleocurrent direction suggests that this highenergy flow originated on the Yucatan platform and was triggered by the Chicxulub impact. We propose that a gigantic flow deposit was induced by earthquake-generated collapse of the Yucatan platform margin owing to ballistic flow from the Chicxulub impact.
