NOGUESS would incorporate magnetic field’s temporal changes in order to explore the avenues how to separate sources of induced magnetization from remanent. The hypothesis is that the induced components relate directly to magnetic susceptibility of the sources. Ability to measure changes in magnetic field in response to an external magnetic field change in geological setting would lead to more detailed information about the nature of the geological sources. Normally, this variation of magnetic field measured during the survey is subtracted from the data sets by using the base station at the time of survey. However, in this case the challenge is to incorporate the changes from the survey magnetometer that correspond to changes detected at the base station with the goal to separate remanent and induced components and produce two magnetic maps. One map would provide concentration of magnetic carriers, while the other would inform about the geologic history recorded in remanent magnetic fields.
