Process of Change in the Geographic Information System Technology In IRAN’s Geology and Exploration
Geophysitst, uses Geographic Information System For studying the spatial Factors related to earthquakes and defining shallow intrusive bodies in different scales considering the fligh height and space (Fig 5)

In economic geology, the Geographic Information System can be used for zoning the mineral exploration and preparation digital economic geological maps including complete mines data and indices (type , coordinations, pargenesis, age, species, country rock the shape of mineral ore) and also it can be helpful in designing exploration model , finding out whether the ore deposit is econimical or not and tracing new exploration location by making mineralization models.
Conclusion
Optimised use of underground mineral resources of the country will have substontial and main role in creating balance and establishing relatively economic self-sufficiency policy and consequently political and economical dependence. On the other hand , if our potential in recognition and row materias exploration as
well as exploitation and processing , using Geographic Information System, increases it will couuse the added volue in mining section and incrcase its share in the national Gross product (NGP) , it will also Facilitate and expand the employment.
