چکیده
LCT-granitic pegmatites as defined by (Cerny, 1991) are anomalously enriched in Li, Rb, Cs, Be, Sn, Ga, Ta>Nb, (B,P,F) and are host to many of the worlds most precious gemstones including emerald, chrysoberyl and topaz (Minas Gerais, Brazil), sapphire and ruby (Afghanistan and Pakistan), and gem tourmaline (Pala District, California). Twelve Minfile (MF) occurrences of LCT-pegmatites are recorded in BC, with all but one located within the Omineca Belt.

Boroujerd-Nezam Abad zone widespread along NW-SE trend in part of Sanandaj-Sirjan zone. Borujerd-Nezam zone consists of hornfels, schist, phyllite, migmatite, granite and granodiorite rock types. Metamorphic (hornfels and schist) and igneous (granitoids) rocks are known as host pegmatitic dykes. Quartz, feldspar, muscovite and tourmaline are the most common pegmatite, and mica are as muscovite ...

In the area SW of Arak, intrusives are emplaced into metasediments of early Mesozoic age. The intrusive rocks vary in morphology, structure and mineralogy, and exhibit various degrees of alterations; Rb-Sr geochronological data have been obtained to constrain their timing. There are three different groups of granitic rocks in the area: (a) the Astaneh intrusion, consisting of granite, biotite g...

Mard-abad calc-alkaline granite formed along the margin of active pull-apart or intra-continental plates, and it is post-collision granite type. Granophyric, perthitic and myrmekitic are main textures that could form from crystallization of hypersolvus source magma, which occurred under water vapor pressure of approximately 2 kb. During this study the temperature of formation of these granites ...

Malmir area is located in the east of Doroud city, in the Sanandaj-Sirjan metamorphic zone. The earliest deposits contain a relatively uniform sequence of slates and phyllites with silisic veins and veinlet. Various granitoid units, with Middle Jurassic age, are the most important geological event that occurred in the area. Microprobe analyses of tourmalines in pegmatites and and quartz-tourmal...
