First zircon ages for Sabalan volcano, northwestern Iran Volcano evolved in two major eruption episodes forming Paleo-Sabalan and Neo-Sabalan. Paleo-Sabalan ages between 4.5 and 1.3 Ma; Neo-Sabalan ages between 545 and 110 ka Multiple ignimbrite forming eruptions during Neo-Sabalan stage Geochemistry consistent with melting of subduction modified mantle after slab breakoff
