dc.descriptionBatholith of Shirkuh, Yazd, is part of the central Iranian structural zone, located southwest of the province. The lithology of this complex comprises mostly monzogranite and granodiorite and some quartz monzonite, quartz monzodiorite and syenogranite.Plagioclase, quartz, orthoclase, biotite and amphibole are the dominant minerals in these rocks. The composition of plagioclases varies from labradorite to oligoclase, and alkali feldspars belong to the orthoclase category. Amphiboles are calcic, rich in iron and Fe-Mg-Mn amphiboles, and range from ferro-hornblende to tschermakite, and tschermakite hornblende. According to various geobarometry methods using the amphibole composition, it is estimated that the calc-alkaline batholith has been formed in a supra-subduction tectonomagmatic environment at 700–900 °C and 0.8–1.5 kbar pressure under high oxygen fugacity. Moreover, based on the thermometry results of feldspars, the emplacement temperature was obtained in the 770–920 °C range by the Anderson method for the Shirkuh granitoid batholithen-US
dc.descriptionO batólito de Shirkuh, Yazd, faz parte da zona estrutural central do Irã, localizada a sudoeste da província. A litologia deste complexo compreende principalmente monzogranito e granodiorito e alguns monzonitos de quartzo, monzodioritos de quartzo e sienogranitos. Plagioclásio, quartzo, ortoclase, biotita e anfibólio são os minerais dominantes nessas rochas. A composição das plagioclases varia de labradorita a oligoclase e os feldspatos alcalinos pertencem à categoria ortoclase. Os anfibólios são cálcicos, ricos em ferro e anfibólios Fe-Mg-Mn, e variam de ferro-hornblenda a tschermakite e tschermakite hornblende. De acordo com vários métodos de geobarometria usando a composição de anfibólio, estima-se que o batólito calcalcalino tenha sido formado em um ambiente tectonomagmático de supra-subducção a 700-900 ° C e 0,8-1,5 kbar sob alta fugacidade de oxigênio. Além disso, com base nos resultados da termometria dos feldspatos, a temperatura de colocação foi obtida na faixa de 770–920 ° C pelo método de Anderson para o batólito granitóide Shirkuhpt-BR
