Abstract
In 1991 it was 55 years since the application of airborne magnetic surveys on USSR territory, and 52 years since its practical usage at geological institutes. It is possible to outline three periods of such a survey. (1) 1936-55. In this period the magnetic field vertical component was measured with the use of an induction magnetometer developed by A.A. Logachev. The main features of this simple instrument is a half-ring collector, a type of suspension, a compensation mode of measuring with a semi-automatic analog recording, and so forth, and a special system of tuning enabling one to receive a root mean square error of the survey in the range of 50-200 nT. With the use of this magnetometer, the territory of 2,000,000 km2 was surveyed, a number of deposits were discovered ( Krasnokamensk iron-ore deposit in South Siberia in 1943 included), geological maps were refined, and in the period of 1948-49 the first survey in the Arctic (for geological zonation) was conducted.
