Thermodynamic calculation of partial melting of peridotite using of the results of calculations of peridotite melting using MELTS, there are a number of shortcomings to application of this thermothe MELTS algorithm has the potential to aid understanding of a wide range of problems related to mantle melting. We review the dynamic model to calculations of mantle melting. In particular, calculated...

u-pb ages obtained on zircons from the investigated migmatites place new constraints on the evolution of the crustal rocks in the takab area. shrimp u-pb dating of inherited zircon in the melanosome parts of mafic migmatites from the takab complex gives a discordant age with an upper intercept of 2961±72 ma (mswd=0.5) and a lower intercept of 24.2±5.7 ma (mswd=1.7). in the concordia diagram, th...

the nain and ashin ophiolites are located in northeastern isfahan province, in western central-east iranian microplate. pillow lavas are one of the most significant cretaceous rock units. the lower partial melting degree in mantle peridotites of ashin ophiolite, and the derived melt by melting their clinopyroxene caused a more basic (basalt) and enriched nature for the ashin pillow lavas, where...
