چکیده
Ariz pluton, covering approximately 65 km2, is located 50 to 65 km north of Bafq city, Yazd province, and is part of the central Iran structural zone. This pluton ranges in composition from diorite-quartzdiorite to granodiorite and is characterized by a calc-alkaline, metaluminous nature. These rocks primarily consist of hornblende, biotite, plagioclase, orthoclase and quartz. In this study, for the first time, the chemical compositions of hornblende, biotite, and feldspars are used to determine the physicochemical conditions controlling crystallization, emplacement depth, and tectonic setting. Thermobarometry based on Al-in hornblende and biotite compositions indicates that crystallization and geochemical closure occurred at pressures between 2.8-1.3 kbar and temperatures of 861-713 °C. Most of the amphiboles from the Ariz pluton are indicative of formation in a suprasubduction environment or subduction-related tectonic setting. New obtained zircon U-Pb ages indicate that the rock-forming of Ariz pluton crystallized around Late Neoproterozoic-early Cambrian boundary, representing the final product of the geological events that mainly occurred during the Late Neoproterozoic (Ediacaran). Magma-forming of Ariz pluton probably originated from partial melting of the subducted Proto-Tethys oceanic crust beneath the northern margin of Gondwana supercontinent or its above mantle wedge, during Cadomian orogeny and was emplaced in an active continental margin.
