A view on Bisotun relief geological conservation(Daryoosh inscription).

 General:
     Bisotun Region is located in the Zagros mountain , about 3 Km cast of Kermanshah,lran. relief Bisotun at Biston Mountain ( Bisotun Formation ) is as one of important Iranian cultural 1-leritages. The tectonic activites and situation at subduction zone of Zagros thrust induced the Joints and many fractures on Massive limestone ( Lower Cretacceous ) Dissolution , Whethering , effecets of Atmospheric precipitation and karsst developing caused to making several huge damages to relief Bisotun.This paper attempt to describe Methods ol Geological Conservation ol cultural heritages especially Dissolution prosses ( karsi ) , causes , principles and method ofconservation.
In this study effective factors on rocky and relief cultural heritages ( or cultural structures ) divided into Genetic effects ( Internal ) and Emposed effects ( External ).Gcnetic effects divided to three groups of Paleoactions , Neoactions and Next action In the end According to investigations and recognize Methods of Restoration were proposed chart of geological conservation.
