THETFORD MINES OPHIOLITE. Serpentinite ( cm across) from Quebec's Thetford Mines Ophiolite Complex, representing ancient oceanic lithospheric peridotite that was metamorphosed during the Taconic Orogeny (Ordovician).. Locality: Thetford Mines area, southeastern Mégantic County, southern Quebec, Chaudiere Appalachians, south of the St. Lawrence River, southeastern Canada. Rare earth element geochemistry of Thetford Mines ophiolite complex, Northern Appalachians, Canada The Thetford Mines complex is a complete ophiolite which is part of an ultramafic-mafic belt within Québec Appalachians. These allochtonous bodies were emplaced during the Early Ordovician. The Thetford Mines complex comprises a lower unit of.
Suprasubduction-zone ophiolites have been recognized in the geologic record for over thirty years. These ophiolites are essentially intact structurally and stratigraphically, show evidence for synmagmatic extension, and contain lavas with geochemical characteristics of arc-volcanic rocks. Photang thrust sheet: an accretionary complex structurally below the Spontang ophiolite constraining timing and tectonic environment of ophiolite obduction, Ladakh Himalaya, NW India RICHARD I. CORFIELD, MIKE P. SEARLE and OWEN R. GREEN. The last section examines the regional occurrence and geodynamic significance of ophiolite belts on different continents. The book reflects the contemporary work of the international community in a most up-to-date treatment of process-oriented questions on the evolution of ophiolites. Also available.
The term ophiolite derives from the Greek ophis (snake) referring to the similarity in appearance between altered ultramafic rocks (serpentinites) and snake skin (from Latin serpentium, via Medieval Latin serpentyn).In the modern sense (for reviews of historical concepts see Alpine mafic magma stem; Steinmann Trinity) an ophiolite is an assemblage of rock types whose petrogenetic and.

The Ingalls Complex is the largest and most complete of several Middle to Late Jurassic ophiolites in northwestern Washington. It structurally overlies the Skagit metamorphic core of the North Cascades and is intruded by the Late Cretaceous Mount Stuart by:
