Purpose. At this stage of our research we study the information content of soil magnetism addressing the environmental, soil science and exploration objectives. This requires the magnetic properties data of unmodified soils at the territories of hydrocarbons prospecting, soil erosion, environmental pollution. We have collected significant soil magnetism data bank in Ukraine. At the same time the mountain-forest soils were generally not studied and poorly understood. Methods. To remove this gap we carried a series of tests at the area of Maniava Waterfall within Bohorodchany district of Ivano-Frankivsk region, in the south-west of the village Maniava. The investigated soils are brown, sometimes podzolic gleyed soils (Haplic Cambisols on the WRB international classification). We used the reconnaissance studies of soil, field magnetic measurements and soil sampling for the next laboratory magnetic research. Results. The results revealed that mass-specific magnetic susceptibility (χ) of the upper humus horizons A is in the range of 15–25×10-8 m3/kg. The transitional horizon B often included gleyed layers, loam clays, flysh rock material. At the same we identified the presence of humus in horizon B, χ = 10–1510-8 m3/kg. The underlying bedrocks in horizon C (like flysh) are characterized by values: χ = 5–10 10-8 m3/kg. The boulder rocks were recorded almost in passing to the riverbed, they are non magnetic: χ = 1×10-8 m3/kg. Novelty. The results indicate that mountain-forest soils of Ukraine Carpathian Mountains may not have a significant influence on the formation of local magnetic anomalies. But sometimes if χ is above 10-8 m3/kg the soil may be microseepaged by hydrocarbon fluid. In this case the information about soil magnetism is important for oil and gas prospecting. Soils with magnetic susceptibility lower then 20×10-8 m3/kg are not informative for oil and gas exploration. Significance. The magnetic properties of soils data of the Folded Carpathians may be used during detailed magnetometer surveys upon oil and gas fields.
