“…This fits with the geodynamic reconstructions of the Carribbean Plate (e.g. Dengo 1985;Burke 1988;Pindell et al 1988;Pindell and Barrett 1990;Meschede and Frisch 1998;. According to Platt (1993) and Thompson et al (1997b), the extrusion mechanism is also driven by the angle between the plate boundary and the displacement vector.…”

Deformation history of the eclogite‐ and jadeitite‐bearing mélange from North Motagua Fault Zone, Guatemala: insights in the processes of a fossil subduction channel

In Guatemala, along the northern side of the Motagua Valley, a mélange consisting of blocks of eclogite and jadeitite set in a metaserpentinitic and metasedimentary matrix crops out. The metasedimentary rocks display a complex deformation history that includes four tectonic phases, from D1 to D4. The D1 phase occurs only as a relic and is characterized by a mineral assemblage developed under pressure temperature (P-T) conditions of 1.00-1.25 GPa and 206-2638C. The D2 phase, characterized by isoclinal folds, schistosity and mineral/stretching lineation, developed at P-T conditions of 0.70-1.20 GPa and 279-4098C. The following D3 and D4 phases show deformations developed at shallower structural levels. Whereas the D1 phase can be interpreted as the result of underplating of slices of oceanic lithosphere during an intraoceanic subduction, the following phases have been acquired by the mélange during its progressive exhumation through different mechanisms. The deformations related to the D2 and D3 phases can be regarded as acquired by extrusion of the mélange within a subduction channel during a stage of oblique subduction. In addition, the structural evidences indicate that the coupling and mixing of different blocks occurred during the D2 phase, as a result of flow reverse and upward trajectory in the subduction channel. By contrast, the D4 phase can be interpreted as related to extension at shallow structural levels. In this framework, the exhumationrelated structures in the mélange indicate that this process, probably long-lived, developed through different mechanisms, active in the subduction channel through time.

“…In addition, while the reconstructions of Blakey (http://jan.ucc.nau. edu/ ∼ rcb7/globaltext2.html), Meschede and Frisch (1998), and Ross and Scotese (1988) indicate islands in the Panama Strait at this time, more recent reconstructions by Scotese (www.scotese.com; Scotese, 2001) do not. Primarily because islands limit, if not prohibit, flow through this narrow gateway, we choose to exclude them from our boundary conditions.…”

Climate model boundary conditions for four Cretaceous time slices

Abstract. General circulation models (GCMs) are useful tools for investigating the characteristics and dynamics of past climates. Understanding of past climates contributes significantly to our overall understanding of Earth's climate system. One of the most time consuming, and often daunting, tasks facing the paleoclimate modeler, particularly those without a geological background, is the production of surface boundary conditions for past time periods. These boundary conditions consist of, at a minimum, continental configurations derived from plate tectonic modeling, topography, bathymetry, and a vegetation distribution. Typically, each researcher develops a unique set of boundary conditions for use in their simulations. Thus, unlike simulations of modern climate, basic assumptions in paleo surface boundary conditions can vary from researcher to researcher. This makes comparisons between results from multiple researchers difficult and, thus, hinders the integration of studies across the broader community. Unless special changes to surface conditions are warranted, researcher dependent boundary conditions are not the most efficient way to proceed in paleoclimate investigations. Here we present surface boundary conditions (land-sea distribution, paleotopography, paleobathymetry, and paleovegetation distribution) for four Cretaceous time slices (120 Ma, 110 Ma, 90 Ma, and 70 Ma). These boundary conditions are modified from base datasets to be appropriate for incorporation into numerical studies of Earth's climate and are available in NetCDF format upon request from the lead author. The land-sea distribution, bathymetry, and topography are based on the 1 • ×1 • (latitude × longitude) paleo Digital Elevation Models (paleoDEMs) of Christopher Scotese. Those paleoDEMs were adjusted using the paleogeographical reconstructions of Ronald BlakeyCorrespondence to: J. O. Sewall (jsewall@vt.edu) (Northern Arizona University) and published literature and were then modified for use in GCMs. The paleovegetation distribution is based on published data and reconstructions and consultation with members of the paleobotanical community and is represented as generalized biomes that should be easily translatable to many vegetation-modeling schemes.

“…How many ophiolitic units can be referred to the unthickned oceanic proto Caribbean crust is difficult to establish because several data suggest that some units should better fit an intra-or back-arc supra-subduction (SSZ) origin. In any case, the near American point of view already put forward by several authors (Beccaluva et al, 1996;Meschede & Frisch, 1998;Giunta, 1993;Giunta et al, 2002Giunta et al, a, 2002b, is therefore favoured with respect to the classic hypothesis of the Caribbean Plate as a " Pacific promontory" (Burke, 1988;Draper & Pindell 2006;Duncan & Hargrave, 1984;Maresch et al, 2009;Pindell & Barrett, 1990;Pindell 2003;Stanek & Maresch 2006, 2009 (Fig.7). In order to compare the various models of the literature (James, 2009 and references therein; lavori vari), some problems need a better resolution for this tectonic phase: 1.…”
