Ultradetailed Environmental Magnetic Investigations in Ukraine

The significant and valuable results at high-resolution environmental investigations using magnetic methods are obtained in Ukraine. The ultradetailed magnetometry is the complex magnetic investigation of the geological surroundings including the magnetic survey with unlimited minuteness and studying of rock-magnetic properties and environmental magnetism including soils. The combination of the ultradetailed magnetometry with equally detailed investigations of the environmental magnetism brings the new conditions for understanding the nature of anomalous magnetic field. These data are very important at the investigations of the flanges outcrops, crystalline basement, prospecting of minerals, oil and gas exploration, agriculture, soil science, ecology. The determination of the accuracy of survey is required at the stage of selecting a rational methodical complex of magnetometry. Investigated objects were reliably identified with an accuracy above 0,5 nT. One of the most important results of the investigations is that one-time survey of the territory is enough. The magnetic characteristics decrease under the conditions of eluvial landscapes and the influence of geochemical processes of salt. The minimal values of the soil magnetism are specific for hydromorphic sites of landscapes. Often, these processes could not be fixed with visual image. In the same time, these hazards effect on the conditioning of agricultural land.
