The investigated area in south west of Razavi Khorasan province located in 1: 250000 topography & geological map of Ferdwos which is considered as part of structural zone of central Iran and as apart of the northern margin of Lut block. According to our field geological investigations and satellite image studies indicate that the main volcanic rocks whit acidic to intermediate composition (rhyolite, dacite, Rio dacite, andesite, quartz andesite, quartz latite andesite) and Intrusive masses are (monzogranite, synogranite, quartz monzo syenite, quartz syenite ) of area can be seen. Magma mainly consist meta-alumina and alumina. The change strike of faults is east – west of south side to north side.K- Feldspar masses are probably the main economic potential of the investigated area.
