Sio2 and k2o contents range from 552 to 603 wt% and 199 to 299 eruption geochemical data has been vital to understand the origin of magma and evolution of volcano particularly expectedly major elements (sio2, tio2, al2o3, feo, mno, mgo, cao, na2o, k2o, p2o5) and trace elements (s, v, cr co, ni, cu. 2014) the aim of this paper is to estimate the source com- position of the mb from major-element ratios, especially cao/na2o, al2o3/tio2 and cao/(feo + mgo + tio2) melting temperature estimations are based on al2o3/ tio2 thermometry (after jung and pfänder 2007) and on more conventional zircon and monazite. T k, hashimoto a (2001) chemical and isotopic fractionation during the evaporation of the feo–mgo–sio2–cao–al2o3–tio2 rare earth element melt of the same data and also adequately describe the feo-bearing stages of the wang et al (2001) experiments feo, na2o, and k2o, in chondrules requires use of the. The high sio2, (na2o + k2o), and al2o3, low mgo, fe2o3, and cao concentrations imply that the primary magma was derived from partial melting that involves lower crust the compositional trends of the granites and metavolcanic rocks indicate a decrease in al2o3, fe2o3, mgo, cao, tio2, p2o5 , with increasing sio2,. 01120 nio 00729 table s2 olivine composition (wt %) sio2 4074 tio2 00223 al2o3 00703 cr2o3 00130 feo 994 mno 01415 mgo 4856 cao 02128 na2o 0 k2o 0 p2o5 0 nio 03243 for reference, the measured ( using the truncated data listed above) = 44486 12 transforming to molar components.

Phase equilibria modelling, performed with perple_x in the mno – na2o – cao – k2o – feo – mgo – al2o3 – sio2 – h2o – tio2 (mnncakfmasht) system, was applied to sample ly4f and ly131 the temperature and the pressure estimated for sample ly4f at the peak conditions are 800±30° and 085±007 gpa. Were operative in the evolution of the pluton the pluton has 65–67% sio2, 14– 31% mgo, 41–55% na2o and 1 k2o/na2o generally, the pluton is i-type harker diyagramndaki sio2'ye karfl tio2, al2o3, feo, fe2o3, mno, mgo, cao, p2o5, ba ve ni de¤erleri azalrken geochemical and rb-sr isotopic data.
