| Abstract/Notes | The Escambray Massif of central Cuba is the largest metamorphic complex exposed in the Greater Antilles of the northern Caribbean area. It can be viewed as an extraordinarily rich archive, documenting (1) processes accompanying early rifting between North and South America, (2) the subsequent eastward passage of the intra-oceanic subduction-zone and island-arc complex of the ‘‘Great Caribbean Arc’’ (GCA) originally bridging the Farallon rims of the Americas to its present position of the Lesser Antilles, (3) the interaction of the northwestern GCA with the northern continental border, and (4) final collision of the GCA with the Bahamas crustal section of North America. The Escambray Massif has recently received renewed attention for its role in allowing Caribbean tectonic history to be studied. In this review, we summarize data and information from both published and unpublished Spanish, Russian, German, and English sources and augment this with our own unpublished geochemical and geochronological data to provide a comprehensive overview. The Escambray Massif is a nappe pile of five major tectonic units with different protoliths and pressure-temperature-time paths, indicative of distinct geodynamic settings. The tectonically uppermost Mabujina Amphibolite Complex (MAC) overlies four units of the Escambray Complex (EC) s.str. It is a lithologically heterogeneous unit that underwent low- to medium-pressure amphibolite-facies metamorphism at about 90 Ma. The lithology of the MAC is similar to that described for the active margin of western Mexico. The two directly underlying high-pressure (HP) metamorphic nappes of the EC represent former oceanic crust (Yayabo Unit) and a me´lange-like mix of sedimentary and igneous rocks derived from a passive margin with exotic slivers of oceanic crust and serpentinite (Gavilanes Unit). Pressures of 14–15 kbar were reached in the Yayabo amphibolites and 25 kbar in the eclogite-bearing Gavilanes Unit. The diachronous timing of maximum HP-metamorphism (80 Ma and 70 Ma, respectively) is due to the oblique collision of the GCA with the southern Yucata´n block during subduction. The MAC and the Yayabo Unit were juxtaposed between 75 and 80 Ma, and joined by the Gavilanes Unit at 68–65 Ma. The tectonically lowest units reached lawsonite-grade, high-pressure greenschist-facies conditions at variable temperatures during subduction at ~60 Ma and were stacked with the other units at ~50 Ma, before the complete metamorphic nappe pile was thrust over the southern Bahamas margin and exposed to erosion. Both the MAC and the EC units bear evidence of tectonic transport by oblique subduction and collision extending from the active Pacific margin along the northern Proto-Caribbean passive continental margins to a final position in the thrust belt bordering the southern Bahamas platform. | ||
