a procedure is presented that synthesizes fractional crystallization separation processes to obtain pure solids from multi-component solutions. the method includes a procedure to generate a network flow model to identify alternative process designs for fractional crystallization. the main advantage of this systematic procedure with respect to other reported procedures is using non-equilibrium s...

three intrusive granitoid bodies from northwest saveh, central iran, are embedded in volcanic sedimentary rocks of the eocene,forming isolated small outcrops: khalkhab quartz monzodioritic units (sio2: ~52-57 wt %) to the northwest, neshveh granodioriticunits (sio2: ~62-71 wt %) to the northeast, and selijerd granodioritic units (sio2: ~63-69 wt %) to the southeast. the khalkhab unit iscomposed...

baft ophiolitic – mélange belt is a part of the ophiolite melange belt of central iran whose genesis is considered as an environment related to tethys subduction at upper cretaceous. major part of intrusive masses of baft ophiolitic – melange form gabbros with the inequigranular texture fine to coarse and pegmatitic, plagiogranites also with inequigranular general texture have been developed wi...

Evidence from abyssal peridotites suggests that significant chemical reaction with peridotite can occur during the early stages of cooling and crystallization of mid-ocean ridge basalt (MORB) magmas. We evaluate the hypothesis that reactive crystallization (crystallization influenced by such melt^rock reaction) could cause magma compositions to evolve along a different chemical trajectory than ...

Introduction: LEW2 consists of abundant, coarse subhedral to euhedral olivine crystals (-FOG()90, typical grainsize -0.5mm) set in a fine-grained intergranular groundmass composed primarily of plagioclase, olivine, and Ca-A1 pyroxene [eg. 1,2]. The groundmass clearly represents a crystallized melt [3,4]. McKay et al. [6] proposed that this interstitial groundmass melt was produced by fractional...
