The mineralogical composition of soils formed on phyllite and alluvium as well as examination of their mineral weathering characteristics should provide an insight into the stage of weathering. Three soil profiles from mountain, plain and low lands were selected. Based on XRD analysis, clay fractions were dominated by chlorite–vermiculite, vermiculite, HIV, illite, mica–vermiculite or mica-smec...

Sangan iron mine with skarn type genesis is located in NE Iran (Khorasan Razavi Province), in the Central Iran zone and NE of Lut Block sub-zone. The Senjedak-III prospect area is one of the six eastern anomalies of Sangan iron mine that encompasses eastern terminal of Khaf- Kashmar- Bardaskan volcano-plutonic belt. The geology of this area consists of a series of igneous (dykes and intrusive b...

The Malayer-Boroujerd-Shazand district (approximately 70 km long) is located in the Sanandaj-Sirjan zone with NW-SE trending, and consist mainly of hornfels, schist, phyllite, migmatite, granite and granodiorite which contain numerous pegmatite and aplitic dykes. Among these rocks, granodiorite, hornfels and schist are main host rocks for quartz, feldspar, muscovite and tourmaline bearing pegma...

Shelgerd area is located south of Mashhad, N.E of Iran, within Binalud Structural Zone. This region is affected by regional metamorphism, slate and phylite are the main metamorphic rocks of the area. Teriassic slate, phyllite, sandstone and Jurassic conglomerates crop out parallel to Sang bast- Shandize fault. Mineralization occurred as vein type, with trend of N65E to N50W with 75 degrees to t...

Aligoodarz granitoidic plutons (Gole -zard and Darreh -bagh) with Middle Jurassic ages are intruded into low grade regional metamorphic rocks (slate and phyllite) and caused aureole of low to medium grade metamorphic rocks (albite-epidote hornfelse facies). Based on precise field, petrographic and geochemistry investigations, the granites belong to the S- type and their composition range from g...
