<p>Bala Zard volcanic rocks are erupted in the Lut Block in Eastern Iran and exposed about 270 Km north east of Kerman city. The volcanic rocks mainly consist of basalt, andesite, dacite, and rhyodacite. Petrographic studies show that several disequilibrium textures such as sieve texture and oscillatory zoning in plagioclase phenocrysts are present in some of the minerals of BalaZard volcanic rocks. Mineral chemistry studies revealed compositional changes along with the textural changes in minerals from the study area. The observed oscillatory&nbsp;zoning profile for the anorthite&nbsp;content (An) of plagioclase suggests repeated injections of mafic melts (replenishment) and mixing with pre-exiting magma and forming rocks with basaltic-andesite composition. The chemical composition of clinopyroxene phenocrysts exhibit calc-alkaline affinity and suggest that Bala Zard volcanic rocks formed in a subduction related volcanic arc.</p>
