چکیده
melt fractions that percolated pervasively throughout the massif and On the basis of their structural and compositional characteristics, had a refractory, calc-alkaline character. Locally, these melts were mafic rocks in the Ronda peridotite are classified into four groups: tapped into cracks forming intrusive dykes. group A (garnet-bearing rocks) occurring in the spinel tectonite domain; group B (spinel websterites) along the recrystallization front; group C (Ti-rich spinel pyroxenites) in the granular tectonite and plagioclase tectonite domains; and group D (Cr-rich pyroxenites) as composite layers along the recrystallization front, dykes in the

Postcollisional mafic igneous rocks record crust-mantle interaction during continental deep subduction
Findings of coesite and microdiamond in metamorphic rocks of supracrustal protolith led to the recognition of continental subduction to mantle depths. The crust-mantle interaction is expected to take place during subduction of the continental crust beneath the subcontinental lithospheric mantle wedge. This is recorded by postcollisional mafic igneous rocks in the Dabie-Sulu orogenic belt and it...
متن کاملPetrological Evolution of the Upper Mantle Beneath the Southern Sanandaj-Sirjan Zone: Evidence from Kuhshah Peridotite Massif, Southeast Iran
The Kuhshah ultramafic complex is located in the south-east of Sanandaj-Sirjan metamorphic zone, near the probable remnants of Neotethys plate in Iran. It consists of highly depleted harzburgites, dunites, chromitite bands and altered gabbros. The ultramafic parts have been intruded by numerous clinopyroxenite dykes and veins. In the harzburgites, there are different generations of olivine, ort...
متن کاملPetit-spot as definitive evidence for partial melting in the asthenosphere caused by CO2
The deep carbon cycle plays an important role on the chemical differentiation and physical properties of the Earth's mantle. Especially in the asthenosphere, seismic low-velocity and high electrical conductivity due to carbon dioxide (CO2)-induced partial melting are expected but not directly observed. Here we discuss the experimental results relevant to the genesis of primitive CO2-rich alkali...
متن کاملTertiary Minette and Melanephelinite Dikes, Wasatch Plateau, Utah: Records of Mantle Heterogeneities and Changing Tectonics
A swarm of minette and melanephelinite dikes is exposed over 2500 km 2 in and near the Wasatch Plateau, central Utah, along the western margin of the Colorado Plateaus in the transition zone with the Basin and Range province. To date, 110 vertical dikes in 25 dike sets have been recognized. Strikes shift from about N80øW for 24 Ma dikes, to about N60øW for 18 Ma, to due north for 8-7 m.y. These...
متن کاملGeneration of Hawaiian post-erosional lavas by melting of a mixed lherzolite/pyroxenite source
Melting of mafic veins in a marble-cake mantle may play an important role in generating isotopic and chemical heterogeneities in mid-ocean ridge and ocean island basalts. Mafic veins have lower solidi than mantle peridotite and will be preferentially sampled during partial melting, particularly at low melt fractions. However, the abundance of mafic components in the mantle or their role during ...
