Samples of bauxite.

The oldest bauxites began to form on earth more than 500 million years ago.

A cartoon explaining the formation of bauxite at this time.

Laterite bauxite.

The most famous laterite bauxites are West African.

Continuation of the cartoon.

In the Soviet Union, Belgorod bauxites were formed in this way, Vysokopolsky in Ukraine and on the Middle Timan.

Tikhvin bauxites.

North-Voronezh bauxites.

South Pacific sedimentary bauxites.

Bauxite mining at the oldest Tikhvin bauxite quarry.

In the Tikhvin bauxites, most of the alumina is in the form of boehmite.

Meso-Cenozoic deposits of Turgai type.

Bauxites from these deposits have a bean structure.

Bauxites of oolitic structure are found in these deposits.

Geologists are following the route.

Geologists on the rocks of the Ural Mountains.

Aerogammaspectrometry makes it possible to detect sedimentary deposits of bauxite enriched with radioactive elements.

The geologist on board the aircraft is conducting observations.

Seismic methods are used in the search for deep-lying bauxites.

The obtained seismograms make it possible to identify areas promising for bauxite.

The method of vertical electric sounding is used to search for Turgai-type bauxites.

A cartoon explaining this method.

Geologists on the bus take readings.

Two-plane electrical reconnaissance is used to survey large areas.

The geologist analyzes the data obtained.

Magnetic exploration allows you to record deposits of a magnetic variety of bauxite.

Modern magnetometers detect even weak magnetic anomalies.

The data is recorded on a paper tape and simultaneously prepared for input into a computer.

Entering information into the computer.

A computer with the help of a cartographic system creates a map of magnetic anomalies.

Analysis of the received data.

In promising areas, research is being conducted with the help of drilling rigs.
