Magnetic survey, one of the tools used by exploration geophysicists in their search for mineral-bearing ore bodies or even oil-bearing sedimentary structures and by archaeologists to locate and map the remains of buried essential feature is the measurement of the magnetic-field intensity and sometimes the magnetic inclination, or dip, and declination (departure from geographic. Two UAMSs have been acquired, and, by now, about km 2 of , magnetic survey has been carried out. In , line km of , UAMS magnetic survey has been carried out in Central Kazakhstan. The task of the survey is geological mapping, in particular—tracing of zones prospective for lead-zinc and iron-manganese ores of Cited by: 1. S.S. Hubbard, N. Linde, in Treatise on Water Science, Magnetics. Magnetic methods obtain information related to the direction, gradient, or intensity of the Earth's magnetic field. The intensity of the magnetic field at the Earth's surface is a function of the location of the observation point in the primary earth magnetic field as well as from contributions from local or. Magnetic surveys are also used to locate a concentration or absence of magnetic minerals in the search for economic ore deposits (Sheriff, ). Variations in the observed magnetic field from the predicted regional field are called magnetic anomalies and are attributed to variations in the distribution of materials having different magnetic.
Sheet‑metal barns, power lines, and other potentially magnetic objects will occasionally be encountered during a magnetic survey. When taking a magnetic reading in the vicinity of such items, describe the interfering object and note the distance from it to the magnetic station in your field book. Airborne magnetic surveys or aeromagnetic surveys are usually made with magnetometers carried by aircraft flying in parallel lines spaced 2 - 4 km apart at an elevation of about m when exploring for petroleum deposits and in lines - km apart roughly m or less above the ground when searching for mineral concentrations. Magnetic Surveys. Magnetic surveys may be very simple or very camplex, depending on the objectives of the survey. The,amplitude of magnetic anom alies range from less than 1 7 to several thousand gammas ; horizontally the extent of these anomalies ranges from less than 1 .
