Abstract :

The Givshad Sub volcanic mass is located in the south of Birjand ophiolite mélange zone. Up to now, from the point of view of establishment structure, this masses, not exactly determined and various assumption presented about to mass such as: A bearing crater volcanic dome or ring dike. On the base, for apparent subject, we do a number of geophysical (geo electric) profiles on the masses various point (internal and external parts). On the base of data, electrical resistances obtained to under layers were different measured in the internal (300-600) and external (10-300) parts of the mass. Thus with analysis electric waves cross speed and comprised with standard puzzles determined, In spite of ring shape, mass has continued in the internal part under quaternary sediments (the maximum thickness of 15m).In finally conclusion, this mass was sub volcanic dome that altered in the internal part due to increasing of its diameter.
