Deformation and seismic anisotropy of the lithospheric mantle in the southeastern Carpathians inferred from the study of mantle xenoliths

Relation between mantle shear zone deformation and metasomatism in spinel peridotite xenoliths of Jeju Island (South Korea): Evidence from olivine CPO and trace elements

“…Vissers et al, 1997;Fabries et al, 1998;Newman et al, 1999). Nevertheless, Falus et al (2008) supposed similarly elevated temperatures (∼900 • C) for the mylonitization of peridotite xenoliths of the EastTransylvanian Basin Volcanic Field (eastern Carpathian-Pannonian Region), which is situated close to the Vrancea subduction zone in the 700-km long fold-thrust belt of the Carpathian Mountains.…”

“…Mainprice and Silver, 1993;Vauchez and Garrido, 2001;Karato et al, 2008 and references therein). Nevertheless, studies dealing with geochemical problems combined with fabric analysis are rare (Bali et al, 2007;Falus et al, 2008;Tommasi et al, 2008), even though the relationship between melt percolation and deformation is known. Studies on natural and experimental partial molten systems suggest that deformation may enhance permeability, favoring melt percolation (e.g.…”

Deformation and hydration of the lithospheric mantle beneath the Kaapvaal craton, South Africa

“…OH concentration in olivine as a function of pressure in the studied xenoliths. For comparison, concentrations in olivine from previous studies on peridotite xenoliths from various cratonic and off-craton localities and in olivine megacrysts in kimberlitic magmas Falus et al, 2008;Grant et al, 2007;Kurosawa et al, 1997;Li et al, 2008;Peslier and Luhr, 2006;Peslier et al, 2002;Stachel et al, 2003) are also displayed. Dashed line shows the water solubility at 1100°C and increasing pressure from Kohlstedt et al (1996).…”

“…For comparison, data obtained in previous studies on peridotite xenoliths from various localities are also shownFalus et al, 2008).…”

Topo-Transylvania: a multidisciplinary Earth science initiative in Central Europe to tackle local and global challenges

“…1) and the adjacent part of the Transylvanian Basin make it a key area to understand the rapid changes of continental topography in an important part of the Carpathian-Pannonian system of Central Europe. These relevant active processes are linked with subduction roll-back, break-off and associated basin (de)formation, volcanism, post-volcanic activity (gas emanations, ore mineralization), earthquakes and tectonic movements (e.g., salt diapirism, volcano spreading Szakács and Krézsek 2006;Falus et al 2008;Ismail-Zadeh et al 2012;Horváth et al 2006;Seghedi et al 2016;Kis et al 2017). These processes are active or have ceased their impact during the recent evolution of the Carpathians-Transylvanian system).…”
