About this deal

During this subduction/accretion event, syn-tectonic sediments were deposited and the activity of the volcanic arc in the northwestern Caribbean (García-Gasco et al. Relative motion designations are shown by convention and keyed to the relative velocity triangles (not to scale of map) in the inset box; for example, 'Pac/NA' is the motion direction of the Pacific lithosphere relative to North America. This model may explain other ophiolitic bodies of the Caribbean arc in Cuba, Dominican Republic and Puerto Rico and elsewhere formed in abyssal/transform fault or forearc settings. Ongoing collision and subduction with a strong strikeslip motion continues today in the eastern Dominican Republic and Puerto Rico-Virgin Islands (Mann et al. En los episodios más tardíos de esta etapa precipita también calcopirita rellenando fracturas y huecos intersticiales entre los fragmentos de sulfuros previos.

The Proto-Caribbean basin (related to the Central Atlantic) formed in between the Americas during Jurassic-late Cretaceous time and started westerly-directed subduction below the Pacific (Farallon plate) in the early Cretaceous, forming backarc, forearc and arc settings in the leading edge of the Caribbean plate (Boschman et al. Volcanic arc activity in the Cuban segment of the Caribbean arc produced sedimentary, volcanic, and plutonic rocks during Cretaceous times (ca. Southern metamorphic terranes: 5- The southern metamorphic terranes are a main feature in the geology of Cuba.

En conjunto, presenta una textura groseramente bandeada en la que alternan irregularmente bandas ricas en pirita, bandas con esfalerita y galena, y bandas de dolomita-ankerita (±sericita, biotita-clorita y apatito criptocristalino), mejor definida hacia el SO del cuerpo mineral. In the western segment of the northern Caribbean orogenic belt (present-day western and central Cuba), arc magmatism was interrupted or attenuated since the late Campanian by episodic collision/subduction of intra-proto-Caribbean passive margin sequences similar to those of the North America-related Maya block (Garcia-Casco et al. Uplift and unroofing of Jurassic-Cretaceous, mantle and crust, arc-and plume-related rock units in the Median Belt of the Dominican Republic exposed basement rocks with a protracted record of tectono-thermal events delineating the evolution of the northern edge of the Caribbean plate.

Convergence largely consumed the Proto-Caribbean by latest Cretaceous-early Tertiary time, triggering collision of the Caribbean arc system with the North American margin, the tectonic emplacement of ophiolitic and volcanic arc units and subducted oceanic and passive margin terranes onto the margin and the formation of the Caribbean Cretaceous-Tertiary orogenic belt (Cruz-Orosa et al. The petrological and geochemical characteristics of antigoritite allow distinguishing two types of rock: i) antigoritite and ii) dolomite-bearing antigoritite.

The movements are: La Quejosita, El panuelo de Pepa, La camagueyana, Los delirios de Rosita, and Los munecos. A fault zone containing a large elongate body of serpentinized peridotite separates the two metamorphosed units. The arc migrated first towards the southeastern flank of the Chortis block, then towards the southern flank of the Maya Block and the Caribeana terrane, and finally towards the Bahamas platform (Pindell et al. Stylish D-Shaped Buckle - D-shaped caribiniers is proved to be the strongest carabiner on the market, and the D-shaped carabeaner provides the largest door opening size.

Some thin tuff beds are present in the southernmost deep water deposits of the North American palaeomargin in western and central Cuba in the Aptian-Cenomanian. Treerunners, cryptic lizards of the Plica plica group (Squamata, Sauria,Tropiduridae) of northern South America. The ophiolitic Villa Clara serpentinite-matrix mélange, central Cuba, forms part of the large ophiolitic belt of the Greater Antilles. Mafic rocks appear as variably sized tectonic blocks within serpentinite that underwent variable alteration at low pressure.though tectonic complexities in the forearc and the backarc led to mid Cretaceous local subduction events that created metamorphic soles associated with ophiolitic units (Lázaro et al. The succeding Paleogene to recent magmatic activity owes its origin to a lithospheric thinning of a continental plate as a consecuence of the absorption of a lower lithospheric mantle. Muestra una estructura zonal con una zona basal discontinua rica en pirita y una zona superior heterogénea en la que varían tanto las proporciones modales de sulfuros+carbonatos (localmente con cuarzo), como la abundancia relativa de esfalerita+galena respecto a pirita. To determine an item's service and warranty coverage in your country, please contact the manufacturer. Features associated with the subduction of the Nazca Plate, such as active calc-alkaline volcanic arcs built on South American crust, only became established in Ecuador, and then Colombia, as the triple junction migrated to the north.
