Abstract
|
The effect of salt domes that basically on whether or not to have the seismicity, is that in this thesis regarding the research and it has been reviewed .The layers of salt that high compressibility and behavior are similar to liquid state due to differences in the density of the surrounding stones with fractures found in Zagros Mountains began to rise that for Salt dome-shaped or mass. Basically waving a mass requires a dynamic effect and cause a mass move in an environment of interaction with its environment, and consequently it would be influential on the adjacent forest. Within the Earth's crust and the areas that saw the fragility and previous fractures, is expected to be operating any stressor irritates and to move on to bring the block involved. The salt dome is also provided under the effect of gravity caused by density contrast with the surroundings and are active and can move a decent candidate, great for placing seismic sources. For vertical movement of salt domes that causes the accumulation of energy can be used to hand three approaches 1-tectonic forces present in the region resulting from the collision of Arabic to page 2-gravity from the density contrast Salt rock with its 3-salt dome growth due to water penetration; That between the first and the most important factor at the top of the salt dome might bulge can be an effect of pressure forces the next side and the differences in the density of the surrounding rocks with salt. We are in this thesis with the help of map drawing show could likely increase the rate of growth of the salt dome in seismicity around 31 can be represented an increase in the rate of The bulge above the salt. The water contained in the salt causes the salt to an immediate acceleration and salt creep up quickly but with regard to the compilation of earthquake occurrences of diagrams per month and the average amount of rain to fall to 31 Active dome plotted it can be said that the likely loss of the rain cannot be liable to thro
