Geochemical make-up of oceanic peridotites from NW Turkey and the multi-stage melting history of the Tethyan upper mantle
(Springer Wien, 2014-02)
We present the whole-rock and the mineral chemical data for upper mantle peridotites from the Harmanci{dotless}k region in NW Turkey and discuss their petrogenetic-tectonic origin. These peridotites are part of a Tethyan ...
Carbonation of mantle peridotite by CO2-rich fluids: the formation of listvenites in the Advocate ophiolite complex (Newfoundland, Canada)
(Elsevier Science, 2018-06)
The mantle section of the Advocate ophiolite (Newfoundland, Canada) contains unique outcrops of listvenite (magnesite-quartz), antigorite- and quartz-bearing talc-magnesite rock, and carbonated antigorite-serpentinite. ...
The Santa Luz chromite-peridotite and associated mafic dykes, Bahia-Brazil: remnants of a transitional-type ophiolite related to the Paleoproterozoic (>2.1 Ga) Rio Itapicuru greenstone belt?O peridotito cromitífero de Santa Luz e diques máficos associados, Bahia-Brasil: remanescentes de um ofiolito transicional relacionado ao greenstone belt paleoproterozóico (>2.1Ga) do rio Itapicuru?
(Asociacion Brasileira de Geologia, 2007-12)
The Santa Luz chromite rich peridotite complex crops out in the Serrinha Block, NE Sao Francisco Craton, aproximately between grey gneisses of the Archean basament and supracrustal rocks of Palaeoproterozoic rocks of the ...
Mantle Recycling: Transition Zone Metamorphism of Tibetan Ophiolitic Peridotites and its Tectonic Implications
(Oxford University Press, 2016)
Large peridotite massifs are scattered along the 1500 km length of the Yarlung-Zangbo Suture Zone (southern Tibet, China), the major suture between Asia and Greater India. Diamonds occur in the peridotites and chromitites ...
Slab-derived components in the subcontinental lithospheric mantle beneath Chilean Patagonia: Geochemistry and Sr–Nd–Pb isotopes of mantle xenoliths and host basalt
(Elsevier, 2017)
In subduction zones, ultramafic xenoliths hosted in alkaline basalts can yield significant information about
the role of potential slab-derived components in the subcontinental lithospheric mantle (SCLM). Chemical ...
A melt-focusing zone in the lithospheric mantle preserved in the Santa Elena Ophiolite, Costa Rica
(2015-08-01)
The Santa Elena Ophiolite in Costa Rica is composed of a well-preserved fragment of the lithospheric mantle that formed along a paleo-spreading center. Within its exposed architecture, this ophiolite records a deep section ...

Sr and Nd isotopic geochemistry of the early ultramafic-mafic rocks of the Mako bimodal volcanic belt of the Kedougou-Kenieba inlier (Senegal)
(SPRINGER HEIDELBERG, 2010)
The Mako bimodal volcanic belt of the Kedougou-Kenieba inlier is composed of volcanic basalts and peridotites interbedded by quartzites and limestones intruded by different generations of granitoids. The early volcanic ...
