Geoduality Theory

1- So far geomorphologists acted as if they explained geomorphic phenomenon within the framework of Causality low. Unlike spatial geography in classical geography there is no necessarily for Causality in relationships among phenomenon and there’s an only generic relationship which can explain the Causality low. But generic relationship has essential difference with that so-called Correlation relationship. Duality is a concept which explains the conflict between two phenomena and is used to refer to a systematic whole. The result of this theory show: •Data analysis in geoduality theory framework can cause a reason in comparison with classical analysis in geomorphology. •Even though dual concept has similarity with coupling but similar techniques for data analyzing can be found among them. •Not only duality concept isn’t the same as dual concept but also philosophically speaking it is just the same as parity word.Soft isostasy: In geology the concept of isostasy was applied by an American geologist called Dutton in 1889 to refer to balanced movements between the crust and mantel. Two supporters of this theory called Pratt and Airy developed this theory into displacement of crust. Soft isostasy is a balanced relation between two parts of the earth's crust which functions gradually in an action and reaction manner when encountering one another.Geoduality: Dual and Duality might be respectively translated into double and the quality of having two parts. It is a term which, meanwhile, contains implicit distinction, unity and is capable of expressing the companionship of two phenomena as without one the other one is not capable of speculating the concept of Duality. What it means by the term Duality in geomorphology is a certain phenomenon which is united with a secondary phenomenon and although it might be considered as a separate and independent entity, there is special bond between them so that the action of one of them is to be recognized in relation with the secondary phenomenon. Concept of duality in geomorphology and it proved, most rely to investigate are focused the land subsidence and the uplift in the adjacent hills. Phenomenon of plains subsidence has been paid attention to by geologists for a long time and almost all the researchers have come to terms that main reason for such subsidence is due to nonstandard exploitation of underground water tables. Such deduction could be acquired as a result of mere studying of plains. The results of the recent studies using the radar interference measuring technique(in the plains of Mahyar, Yazd-Ardakan, Ardebil and Orzoueiyeh) show that the subsidence is a phenomenon which takes place along with another phenomenon called Uplift which is the contrary of aforementioned phenomenon. These phenomena operate in connection with one another and are united which leads to a type of procedural fecundation. The function of these phenomena toward each other is one of the obvious proofs in geomorphology which is not limited to this only, but many other geomorphologic procedures can have the same relation with one another, such as decrease in temperature and civil expansion in Iran or heat and civility contraction in Iran. Duality is a regular coordination of two opposing or complementary parts which is known as a whole. The main purpose of this theory is to explain a particular type of connection among phenomena and it is entitled Dual. In order to reach this goal the subsidence phenomenon is studied which function in accordance with the up lift phenomenon the aim of this theory is to explain the relation between the phenomena, subsidence and up lift in neighboring regions. Researchers believe that the reason for subsidence is in direct relation with ground water withdrawal. In fact, in this theory the process of plains subsidence is attributed to another process which is considered to be in twin relation with subsidence and the aforementioned up lift takes place in the neighboring heights of these plains.
