Petrologia e petrogênese do maciço intrusivo de SiahKuh no sul de KhoshYeilagh
Palavras-chave:
Gobbro, diorito, ambiente extensível, SiahKuh, Irã.Resumo
SiahKuh está localizado na parte nordeste da cidade de Shahrood e na zona leste de Alborz. A área de estudo utilizando modelos geoquímico onde foram utilizadas 60 amostras rochas intrusivas, revelou que a região composição petrological consiste gabro, Monzodiorita, sienite, diorite .. Monzonite e plagioclase. Piroxena e olivina são os principais minerais de Gabro e Diorito. Texturas granulares, intergranulares e ópticas também são observadas. No sienito e monzonito, plagioclásio, feldspato alcalino e, às vezes, quartzo, granular e variolite podem ser observados. Com base em geoquímico, magma produzido a partir de rochas para alcalina calca alta potássio intermediário e anomalias negativas de Nb, Rb, P e enriquecimento das rochas na região a partir de elementos de terras raras (LRRE) e a alta proporção de LREE / HREE representa a propagação da crosta e uma indicação da presença da fase de granada na fonte do manto. Magma de basalto inicial foi criado a partir de um manto com uma composição de Lerzolite-Garnet com um ponto de fusão de 12-15%. Evidências estruturais sugerem a formação dessas rochas na fenda intercontinental. A formação dessas rochas pode ser atribuída aos efeitos das fases de tração intercontinental associadas a falhas profundas durante as fases orogênicas alpinas no período do Eoceno.
