The Caribbean oceanic crust was formed west of the North and South American continents,
probably from Late Jurassic through Early Cretaceous time. Its subsequent evolution has …

Plate tectonics is the governing theory that unifies the Earth Sciences and is unique to Earth.
The sinking of lithosphere in subduction zones drives plate tectonics but exactly how and …

Estimates of global growth rates of continental crust critically depend upon knowledge of the
rate at which crustal material is delivered back into the mantle at subduction zones and is …

New laboratory experiments using granulite xenoliths support a dual origin for I-type
granites as primary and secondary. Primary I-type granites represent fractionated liquids …

Abstract The 110,000 km2 Yucatan Basin in the northern Caribbean Sea is critical for
understanding the Late Cretaceous to Recent tectonic evolution of the Caribbean‐North …

Cuba is the largest island in the Greater Antilles, and its geology records three important
episodes:(1) the Jurassic breakup of North and South America (Pangea) and associated …

Abstract The Loma Caribe peridotite body is mainly composed of serpentinized spinel
harzburgites and lherzolites and minor orthopyroxene-bearing dunites and dunites. Modal …

Little mineralogical evidence is left of the recycling of continental and oceanic crust into the
mantle at subduction zones. Zircon, because of its exceptional robustness, is probably the …

Abstract The Greater Antilles islands of Cuba, Hispaniola, Puerto Rico and Jamaica plus the
Virgin Islands host fragments of the fossil convergent margin that records Cretaceous …

Exotic blocks of massive antigorite-serpentinite (antigoritite) document a deep-seated
subduction channel in the Villa Clara serpentinite-matrix mélange, central Cuba. The …
