    The Baladeh volcanic area in Northern Iran (specifically located in Central Alborz) contains continental alkaline basaltic volcanic outcrops. The most significant minerals in this group of rocks are plagioclage and pyroxene. Accordingly, these minerals were studied and assessed via mineral geochemistry. Compliant with our analysis, the chemical composition of pyroxene and plagioclage are in the range of diopside-augite and bitonite-labradorite, respectively. The temperature and thermodynamic conditions of the parent magma were estimated based on the diagrams of mineral chemistry. High oxygen fugacity, medium to high pressure range, temperature 600-1200 C were the most important conditions governing the parent magma. Geochemical and mineralogical tectonomagmatic diagrams indicate that these basalts are formed locally in an intercontinental tensile basin (constituted as a consequence of the lithospheric thinning of eocene compaction processes). Volcanic assemblages are induced by the formation lava due to the removal of adiabatic pressure from metasomatized mantles, formed as small-scale volcanic rocks that represent an alkaline volcanism and metamorphic rocks with a similar composition to primary lava-derived (or near-primary) lava. Elemental ratios (such as Zr/Nb, La/Nb) represent and are indicative of an elemental model of magmas formed by multiple degrees of smelting of garnet-bearing harzburgite and heterogeneous mantle sources.
