“…These findings are in agreement with the conclusions presented by Benford et al (2012), Symithe et al 2015, andCalais et al (2016). The Chorotega block is moving about 10 mm/a in the N60°E direction with respect to the Caribbean plate.…”

“…In Central America, we introduced the four main blocks Maya, Chortis, Chorotega, and Panama following Boschman et al (2014), Burke et al (1984), DeMets et al (2007, Pindell et al (1988), andJames (2007). In the Caribbean, we followed the proposals of Symithe et al (2015) and Calais et al (2016) and considered the blocks Gonave, Hispaniola and Puerto Rico-Virgin Islands in the north-eastern plate boundary. Mexico and Cuba were assumed to lie on the North American plate.…”

“…Following Symithe et al (2015) and Calais et al (2016), we consider three main blocks in the north-eastern Caribbean plate boundary (Fig. 14): the Gonave block (Rosencrantz and Mann 1991) is located in the west and it is limited by the Enriquillo and Oriente faults and the Plateau Central-San Juan valley area.…”

“…Based on our computed Moho depths and Vp/Vs ratios, and with additional constraints from the major thrusts identified at the surface and the geodynamic reconstructions Pubellier et al, 2000;Calais et al, 2016), we propose a geological model along a N-S profile across Haiti (Fig. 10).…”

Haiti, located at the northern Caribbean plate boundary, records a geological history of terrane accretion from Cretaceous island arc formations to the Eocene to Recent oblique collision with the Bahamas platform. Little is presently known about the underlying crustal structure of the island. We analyze P-waveforms arriving at 27 temporary broadband seismic stations deployed over a distance of 200 km across the major terrane boundaries in Haiti to determine the crustal structure of western Hispaniola. We compute teleseismic receiver functions using the Extended-Time Multi-Taper method and determine crustal thickness and bulk composition (V p /V s ) using the H-к stacking method. Three distinctive and fault-bounded crustal domains, defined by their characteristic Moho depth distributions and bulk crustal V p /V s , are imaged across Haiti. We relate these domains to three crustal terranes that have been accreted along the plate boundary during the northeastwards displacement of the Caribbean plate and are presently being deformed in a localized fold and thrust belt. In the northern domain, made up of volcanic arc facies, the crust has a thickness of~23 km and Vp/Vs of 1.75 ± 0.1 typical of average continental crust. The crust in the southern domain is part of the Caribbean Large Igneous Province (Caribbean LIP), and is~22 km thick with Vp/Vs of 1.80 ± 0.03 consistent with plume-related rocks of late Cretaceous age. Significantly thicker, the crust in central Haiti has values of Moho depths averaging~41 km and with Vp/Vs of 1.80 ± 0.05. We propose that the central domain is likely constructed of an island arc upper crust with fragments of dense material originating from mafic lavas or LIP material. We produce a crustal profile along a N-S transect across Haiti accounting for the surface geology, shallow structural history, and new seismological constraints provided by variations of crustal thickness and bulk composition.

How transpressive is the northern Caribbean plate boundary?

et al. 2016

International audienceTranspressive deformation at the northern Caribbean plate boundary is accommodated mostly by two major strikeslipfaults, but the amount and location of accommodation of the compressional component of deformation is still debated.We collected marine geophysical data including multi-beam bathymetry and multichannel seismic reflection profiles alongthis plate boundary around Hispaniola, in the Jamaica Passage and in the Gulf of Gonâve. The data set allows us to imagethe offshore active strike-slip faults as well as the compressional structures. We confirm that the Enriquillo-Plantain-GardenFault Zone (EPGFZ) in the Jamaica Passage has a primary strike-slip motion, as indicated by active left-lateral strike-sliprelatedstructures, i.e.: restraining bend, asymmetrical basin, en echelon pressures ridges and horsetail splay. Based ontopographic cross-sections across the EPGFZ, we image a very limited compressional component, if any, for at least thewestern part of the Jamaica Passage. Toward the east of the Jamaica Passage, the fault trace becomes more complex and weidentify adjacent compressional structures. In the Gulf of Gonâve, distributed folding and thrust faulting of the most recentsediments indicate active pervasive compressional tectonics. Estimates of shortening in the Jamaica Passage and in the Gulfof Gonâve indicate an increase of the compressional component of deformation towards the east, which nonetheless remainsvery small compared to that inferred from block modelling based on GPS measurement
