Are the Taitao granites formed due to subduction of the Chile ridge? [PDF]
, 2009 The Taitao granites are distributed around the Late Miocene Taitao ophiolite (5.66 ± 0.33 Ma to 5.19 ± 0.15 Ma) exposed at the western tip of the Taitao peninsula, southern Chile, ~ 50 km southeast from the present day Chile triple junction.

Ophiolites in Earth History [PDF]
Eos, Transactions American Geophysical Union, 2004 I began my undergraduate studies in geology in 1974, shortly after the release of the now famous “Anonymous” report on the first Penrose Conference on Ophiolites (Geotimes, 1972). My early geology courses were filled with information on the nature of the seafloor, with details supplied largely from on‐land studies of ophiolites.

Geochemistry Geophysics Geosystems, 2015 Analyzing subduction initiation is key for understanding the coupling between plate tectonics and the underlying mantle. Here we focus on suprasubduction zone (SSZ) ophiolites and how their formation links to intraoceanic subduction initiation in an ...

Geodynamic setting and origin of the Oman/UAE ophiolite [PDF]
, 2012 The ~500km-long mid-Cretaceous Semail nappe of the Sultanate of Oman and UAE (henceforth referred to as the Oman ophiolite) is the largest and best-preserved ophiolite complex known. It is of particular importance because it is generally believed to have

Nurali Ophiolite Massif (the Southern Urals): Geological, Structural, and Mineralogical Features
Vestnik Permskogo Universiteta: Seriâ Geologiâ, 2018 An overview of a geological structure of Nurali massif is presented. Compositional data of ultramafic rocks from mantle section and transitional mantle-crust assemblages, and chemistry of accessory and ore-forming Cr spinels are examined.

A Jurassic oceanic core complex in the high-pressure Monviso ophiolite (western Alps, NW Italy)
, 2015 The eclogite-facies Monviso ophiolite in the western Alps displays a complex record of Jurassic rift-drift, subduction zone, and Cenozoic collision tectonics in its evolutionary history.

The older ultramafic rocks of Aberdeenshire, similarities to SSZ ophiolites and significance for regional tectonics [abstract] [PDF]
, 2008 It has long been known that there are at least two phases of mafic-ultramafic magmatism in NE Scotland (Read 1919), the well known Younger Gabbro suite and a lesser known ‘Older suite’.
