Abstract Mantle peridotites from the External Liguride Jurassic ophiolites (Northern Apennines, Italy) show diffuse occurrence of pyroxenite bands, recording melt migration and crystallization at lithosphere-asthenosphere boundary, during old, pre-Jurassic stages their subcontinental lithospheric mantle evolution. We present coupled microstructural geochemical study profiles across various type...

in order to study of variation and relationships between yield and quality traits, 14 domestic populations of bitter vetch (vicia ervilia) were collected from different parts of lorestan province and sown in two separate experiments under irrigated and dry land farming system using randomized complete block design with three replications in khorramabad, iran during 2005 and 2006. data were coll...

introduction geological background ophiolites have played a major role in our understanding of earth’s processes ranging from seafloor spreading, melt evolution and magma transport in oceanic spreading centers, and hydrothermal alteration and mineralization of oceanic crust to collision tectonics, mountain building processes, and orogeny. they provide the essential structural, petrological, geo...

Data collated from subalkaline lavas and dikes of Palaeogene ophiolites the SW Pacific in Papua, New Guinea, Caledonia, North Island, Zealand interpreted as having formed first upon subduction initiation, are investigated to determine whether these MORB like, similar other initiation IBM forearc. ophiolite mostly tholeiitic basalt; however, calc-alkaline comprise ~ 25% samples. Major element ab...

We investigated the crystal and structural behavior of Cr-bearing spinels from Archean chromitites Sittampundi (India), which had been subjected to very high-grade metamorphism. The data show that their oxygen positional parameters are among highest ever recorded for with similar Cr# Mg# those found other occurrences. general agreement between electron microprobe Mössbauer indicates analyzed st...
