Ophiolites, and discussions on their origin and significance in Earth's history, have been
instrumental in the formulation, testing, and establishment of hypotheses and theories in …

Abstract Northwestern South America preserves a record of the assembly of western
Pangaea, its disassembly and initiation of the far western Tethys Wilson Cycle, subsequent …

Ophiolites are suites of temporally and spatially associated ultramafic, mafic, and felsic rocks
that are interpreted to be remnants of ancient oceanic crust and upper mantle. Ophiolites …

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 …

Regional grou**s of a majority, or all, of Earth's crustal blocks have occurred several times
in Earth history, but only the most recent supercontinent Paleozoic Pangea/Gondwana, is …

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 …

The margins of the Caribbean and associated hazards and resources have been shaped by
a poorly understood history of subduction. Using new data, we improve teleseismic P-wave …

Plutonic and hypabyssal porphyritic granitoids (and their volcanic equivalents) are important
constituents of the composite geological record of the Colombian Andes, not only from a …

Tholeiites occur in a variety of geological settings, eg, mid-ocean ridge, back-arc basin,
ocean island, island arc and intra-continent, and their geochemical and isotopic …

We integrate known and suspected Meso-American plate motions with the geochronology of
Caribbean arcs and Central American HP/LT belts to promote two primary concepts. The first …
