Kursk Magnetic Anomaly

in the earth's crust can be hidden huge mineral deposits.Places where a cluster makes it appropriate extraction of iron ore and other resources, called pools.Thus, the iron ore basin is one of the main sources of value to the country's production of the metal.On one of these large pools and would like to talk more.Kursk magnetic anomaly is located near the town of Zheleznogorsk, is based at the mine in the late 60s.Nevertheless, the city is quite large, it is home to almost one hundred thousand people.It is the second largest among the cities of Kursk region.

Kursk magnetic anomaly is a huge and rich pool, one of the most powerful in the world reserves of iron ore (about 31 billion tons).Swimming stretches for a distance of about 600 kilometers and is located on the territory of several regions of Russia: Belgorod, Orel, Bryansk and Kursk.Deposits of iron ore include the ferruginous quartzites and magnetite, Precambrian granitoids.They are developed underground and open pit (eg Korobkovsky, Mikhailovsky, Lebedinsky and Stoilensky mines).Kursk anomaly, and is rich in land resources, black soil with humus content of 5 to 13%.Because of the active ore mining fertile soil loses its area and decreases rapidly.

Kursk magnetic anomaly was studied in the Soviet period, in 1931.The largest enterprise in the development of its oil fields in a given time is Lebedinskoye Joint Stock Company Mining Processing Plant.The width of the pits reaches five kilometers depth - about 700 meters.

Some large deposits of KMA were discovered much later than the first 60 years of the last century.This anomaly was accidentally discovered by academician PB Inohodtsevym in the late 18th century, when mapping land surveying in the European part of Russia.When conducting research scientist in the Belgorod region magnetic needle instead of pointing to the north, began to spin wildly.A hundred years from this strange anomaly encountered associate professor of Kazan University Smirnov, who led the geomagnetic survey.It was only nine years old assistant professor of Kharkov ND Nikolai Pylchykov conducted special studies in the field of the Kursk magnetic anomaly, and realized that there are huge deposits of minerals.They had found new areas of deposits.The great merit of the study by Professor KMA EE Leist, who for many years has studied border anomalies and the depth of it minerals.Since 1920, more carefully began her study commission headed by Gubkin.After the war, there was an active exploratory drilling, resulting in identified rich deposits of iron ore.

In the 60s began to function Lebedinsky and Mikhailovsky mines in 1969 - Stoilensky mine.They are remarkable superficial deposits of minerals and low water content.The platform cover rocks of Precambrian found deposits of bauxite, cement raw materials, phosphate, construction of clay and sand.On the basis of Kursk Magnetic Anomaly in the future planned construction of a huge industrial complex of world importance to the extraction of iron ore to many tens of millions of tons per year.

Prioskolskoye developing field of Magnitogorsk Iron and Steel Works - iron ore reserves are up about 45 million tons, including the non-oxidized ferruginous quartzites.Mikhailovskoye - one of the oldest and largest fields.It is near the small town of Zheleznogorsk mining stocks are up about eleven billion tons of mining and processing enterprise developed Mikhailovsky.Chernyansky mine has reserves of about two billion tons of iron ore, and is located in shallow water - 160-200 meters.Currently, Kursk magnetic anomaly is the world's largest supplier of iron ore and stores are still many rich mineral deposits.
