Abstarct: Nowadays geophysical exploration methods have extensive applications in exploration of mextallic ore deposits, mainly due to their relatively good results, low costs and high speed. Considerable contrast between physical properties of mextallic ore deposits and their host rocks have enabled us to explore them using various geophysical methods. Mercury is one of mextallic minerals having high conductivity in its pure form. However, mercury in its deposits is often observed as cinnabar that is electrically resistive. For exploration of mineral deposits in an area, we can use different geological, geochemical and geophysical methods, and then, by integrating their results, we determine the preference of exploration zones. To determine mercury mineralization limits in Khangoi area, we have used different geophysical methods, namely resistivity, induced polarization (IP) and very low frequency (VLF) electromagnetic methods, and finally, we have presented a suitable and correct interpretation using geological evidences and geochemical studies. Often quite a large number of data is acquired using the VLF method, but little quantitative information is obtained from the data. Using Fraser filter and current density pseudo-section, data. It is baxsed on reduction of background noise and avoiding an increase in random noises. If the noise in the study area is in the form of background and unique noise, the filter eliminates the noise. However, the conditions of the data acquisition in the area are often otherwise, so that random noise in addition to background noise affects the data. In these situations, Fraser filter not only reduces random noise but also causes increasing the noises. This is a weakness of this filter. By modifying this filter to reduce noises, we can obtain modified Fraser filter that is used in this research work for the first time in Iran, and its advantages have been shown in this thesis. The results of using different geophysical methods (i.e. resistivity, IP and VLF) and geochemical and geological methods were integrated, and finally, two main mineralization trends, one associated with major fault of the study area, and the other in the vicinity of minor faults of the area were recognized. Therefore, combining exploration information and obtaining a suitable patter from mercury mineralization, we explored mercury mineralization zones in the area.
