Ophiolite genesis and global tectonics: Geochemical and tectonic fingerprinting of ancient oceanic lithosphere
Y Dilek, H Furnes - Bulletin, 2011 - pubs.geoscienceworld.org
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 …

Plate tectonics and the Archean Earth
If we accept that a critical condition for plate tectonics is the creation and maintenance of a
global network of narrow boundaries separating multiple plates, then to argue for plate …

Geochemical fingerprinting of oceanic basalts with applications to ophiolite classification and the search for Archean oceanic crust
JA Pearce - Lithos, 2008 - Elsevier
Two geochemical proxies are particularly important for the identification and classification of
oceanic basalts: the Th–Nb proxy for crustal input and hence for demonstrating an oceanic …

Recognition of ocean plate stratigraphy in accretionary orogens through Earth history: A record of 3.8 billion years of sea floor spreading, subduction, and accretion
Ocean plate stratigraphy (OPS) is a term used to describe the sequence of sedimentary and
volcanic rocks deposited on oceanic crust substratum from the time it forms at a spreading …
