The studied volcanic alkaline rocks with 32.7+6 Ma years age are croped out along the south – east of Urumiyeh - Dokhtar Volcanic Belt in Kerman province. Based on the TAS classification these rocks are divided in to tephriphonolite and phonolite which belong to high-K alkaline rocks. These rocks are composed of pyroxene, plagioclase, sanidine, nepheline, analcime and titanomagnetite minerals. Diopside is the only pyroxene identified in the study area. In the most of the phenocrysts the amount of MgO in the core is more than the rims while the amount of FeO is high in the rims. This trend shows a normal fractionation during magmatic evolution. The composition of pyroxene phenocrysts is from WO_47.8 En_38.8 FS_13.4 to WO_45.6 En_35.7 FS_18.8. Sanidine is the only K-feldspar present in these rocks and has a composition ranges from Or_62.7 to Or_93.8. Most of the plagioclase phenocrysts have Ca-rich cores and more Na-rich rims which is attributed to normal magmatic fractionation. The composition range of plagioclase is An_50.83 to An_59.2. Trapezohedrs of analcime comprise up to 40% of the rocks and the composition of the analcime trapezohedrs are remarkably homogeneous. The analcime is interpreted as having formed by ion-exchange pseudomorphous replacement of primary leucite, either during cooling of the lava or shortly afterwards. Titanomagnetite is a very common equant grain in groundmass of all the studied samples. The Fe-Ti oxide crystals are relatively Ti-rich and are classified as titanomagnetite.

The Bozqush, Kaleybar, and Razgah foid-bearing syenites are located in East Azarbaijan province, NW Iran. Mineral chemistry determined for the amphiboles and clinopyroxenes of intrusions to specify elemental exchange, magmatic affinity, and tectonic setting. Chemical composition of the amphiboles varies from magnasio-hastingsite to ferro-pargasite. This study shows that the Kaleybar amphiboles are richer in Ca+^IVAl than the Bozqush ones and Ca^IVAl=SiNa exchange is the main substitution. According to mineral chemistry, the clinopyroxenes are diopside. Considering the atomic proportion of Wo, En and Fs in the studied clinopyroxenes, variation in end-member components mostly involve the interchange of En and Fs. Moreover there is ^M2Ca^M1(Fe²⁺,Mg) = ^M2Na^M1Fe³⁺  exchange in the clinopyroxenes. The Composition of clinopyroxenes and amphiboles indicate that they were derived from volcanic arc miaskitic magma at relatively low pressures. Based on Al and Ti contents, thermobarometry of the amphiboles show pressures of 6±1 and 7±1 kbar for the Bozqush and Kaleybar intrusions respectively and temperature of 900±100 ˚C.
