A new plate tectonic model of the Caribbean: Implications from a geochemical reconnaissance of Cuban Mesozoic volcanic rocks
Accreted terranes, comprising a wide variety of Jurassic and Cretaceous igneous and sedimentary rocks, are an important and conspicuous feature of Cuban geology. Although the Mesozoic igneous rocksExpand
Empirical approach to estimating the composition of the continental crust
The continental crust has ultimately been extracted from the mantle and knowledge of its composition is therefore fundamental to an understanding of the chemical evolution of the Earth. Attempts toExpand
Cretaceous Basaltic Terranes in Western Colombia: Elemental, Chronological and Sr-Nd Isotopic Constraints on Petrogenesis
Accreted terranes comprising Mid to Late Cretaceous picrites, basalts and dolerites occur in three north–south trending belts in western Colombia, in the Central Cordillera, Western Cordillera andExpand
No Oceanic Plateau—No Caribbean Plate? The Seminal Role of an Oceanic Plateau in Caribbean Plate Evolution
Oceanic plateaus are areas of elevated and anomalously thick oceanic crust that are believed to form by enhanced partial melting in a mantle plume that is hotter than ambient upper asthenosphere.Expand
The nature and provenance of accreted oceanic terranes in western Ecuador: geochemical and tectonic constraints
Western Ecuador consists of a complex tectonic mélange of oceanic terranes accreted to the continental margin from Late Cretaceous to Eocene time. New geochemical data from these accreted terranesExpand
Tectonic evolution of the Caribbean and northwestern South America: The case for accretion of two Late Cretaceous oceanic plateaus
It is widely accepted that the thickened oceanic crust of the Caribbean plate, its basaltic accreted margins, and accreted mafic terranes in northwestern South America represent the remnants of aExpand
Trace element geochemistry of orogenic igneous rocks and crustal growth models
Some of the more important constraints on crustal growth mechanisms are reviewed in relation to the trace element composition of orogenic igneous rocks, with specific reference to granitoids, and inExpand
Geochemical characteristics of basaltic volcanism within back-arc basins
Summary Back-arc basins are formed by extensional processes similar to those occurring at mid-ocean ridges. However, whereas the magmas erupted along the major ocean ridges are predominantly LILExpand
The Loch Maree Group: Palaeoproterozoic subduction–accretion complex in the Lewisian of NW Scotland
The Lewisian complex of northwest (NW) Scotland has long been correlated with intercontinental Palaeoproterozoic belts of the North Atlantic region but uncertainty about the age and origin of theExpand
