Induced Polarization Method And The Electromagnetic Method To Find The Metal Mines

Today, deep prospecting single geophysical methods can not effectively achieve the purpose, so the combination of two or more methods of exploration is necessary especially for layer control deposits. According to various definitions of apparent resistivity sensitivity to noise and underground media, it was suggested that the apparent resistivity integrated interpretation method, the inversion results, it increases the constraint only limited understanding. In relying on the project of the integrated use of the induced polarization method (time domain induced polarization for example) and the Electromagnetic Method (EH4electromagnetic imaging system, for example) to detect abnormal suspicious areas.Time domain induced polarization method is a branch of IP law, it is rock, ore, the difference of the induced polarization effect in the artificial DC field source under measurement in the polarization electric field in the land of rock, ore, in order to solve the geological problems a kind of electrical prospecting. EH4electromagnetic imaging system is a combination of a part of the controlled source and natural source magnetotelluric sounding system, the electromagnetic method belongs to the high-frequency electromagnetic sounding technology.The main idea of this paper is the comprehensive utilization of time domain IP and EH4electromagnetic imaging system two geophysical methods to find a stratabound polymetallic deposit, in order to achieve its intended purpose and in the course of the study, Analysis of some of their own experience and understanding. Nature, there is a class of stratabound deposits, the induced polarization method can be reflected in the polarization rate exception, the electromagnetic method to measure deep in the vertical direction can be found in the strata-bound deposits of rock, so the combination of the two are complementary, the practical application of this has been validated in the studyMagnetotelluric sounding data processing, the static correction has been plagued by geophysical workers. If not handled properly, the large errors in the inferred depth occurs, false steep deep fault or large vertical extension of abnormal body seriously affected the interpretation of the results. Therefore, the static correction problem is very important. This pilot study electromagnetic data processing business software MT Soft, static effect correction in the processing chain, is the inversion of induced polarization as the background, try a different window and parameters in order to find the best calibration resultsData combined with a number of papers, the article also described some of the static effect correction processing, due to limited capacity, the author is not its in-depth study the geophysical can these pilot study in order to obtain more suitable for static effect correction...
