The Shabil area is located approximately 50 km east of Meshkinshahr city, Ardabil Province, northwestern Iran. According to geochemical studies, the Eocene volcanic rocks of this area often have basaltic, alkali basaltic, and trachyandesitic compositions. Geochemical investigations indicate that these rocks are predominantly metaluminous, high-potassium calc-alkaline, and shoshonitic, and their geochemical characteristics are consistent with post-collisional arc settings. The enrichment of LILE elements and the depletion of HFSE elements observed in samples from the Shabil area are consistent with the characteristics of volcanic rocks associated with magmatic arcs. The enrichment of LREE elements relative to HREE elements in the Eocene volcanic rocks of the study area may indicate the involvement of subduction-related processes or crustal contamination of the magma.
