The Induced Polarization Method And Its Applied Research In Fujian, A Molybdenum Metal Mining

Dual frequeney induced polarization method put forward and realized by professor He ji shan china engineering council academician of Central South University in the 20th century 1970s.It is a unique method put forward by Chinese and instrument invested by Chinese in geophysics region and a kind of frequency domain geophysical exploration method. The successful application of double frequeney induced polarization method in prospecting mineraland groundwater and so all, lead to our attempting to detecting under ground gob by this way.Firstly thesis summarize the development and the research and application status of induced polarization method(IP), clarifying the the research purpose and meaning. Secondly, based on the profound understanding of physical mechanism of the IP , we probed into the fundamental of double frequency IP method, including the equivalency of frequency domain and time domain, observation scheme and parameters, frequency characteristics and attentional points for field work. On the fundation of these, we analysed the geological and geophysical features of the work area, the layout of the survey grid, the working method, and the quality evaluation of the observed datum. After profound study of the data processing of the double frequency IP method, and the data of the whole area(41 survey lines and 201 survey points) were processed, approving result could be acquired. Finally, elaborate conclution and interpretation from the processing results have been made, and the drilling holes have been planed at the favorable metallogenic location.
