Description

Introduction The studied area is located in 54 Km from North West & Arak & in east of Shara River. The aim is structural- geological study, following of mineral mineralogic studies, some samples were gathered what their explanation has been mentioned in appendix of (1) and (2). The explanation & decomposed data for desire elements has been represented in section (2-5-3). Variation of lithologic facieses involve area is equal & tectonic - stratigraphy zone of Mahabad - Menujan. Oldest facieses of the area contain shale & lower Jurassic sandstone which has out crop in western & south western part & often sedimentary out crop of region is formed free lower cretaceous combination units. Numerous injections from medium to basic composition (in diorite & diabase) have out crop in youngest unit of mentioned deposits. Big structural event results in Regional metamorphism & calcareous shale in unit K5 and it has turned them to slate & micaschist in more distance from area and eastwards. Most shape of region structure is a part of multicline which has a plunge to south east & its trend is NW-SE, while the region faults with same trend & trends of NE-SW,  N-S & also W-E.
