HISTORY BEGIN

Aeronautical geophysical work was carried out in Vietnam from 1961-1963 when the General Department of Geology cooperated with the Soviet Union to survey from the air at a scale of 1:200,000 North Vietnam’s mainland. In 1962-1963, aeronautical radiometric measurements were carried out at 1:25,000 scale on an area of 10,000 km2 along the Red River and the South of the old zone IV. In 1964-1965, aerial measurements were carried out at a scale of 1:25,000 over an area of 1,000 square kilometers in Hebei province.

In 1964, when the US imperialists bombed the northern provinces of Vietnam, the aeronautical geophysical survey was interrupted. In 1965, the General Department of Geology assigned the task of aeronautical geophysical survey to Delegation 35. The first aeronautical geophysical flight team was established, captain Dinh Bang, vice captain in charge of engineering: Nguyen Xuan Son.

In response to the fast-paced mineral prospecting and exploration for the socialist industrialization in our country, the Government Council issued Directive No. 1041/KT3 dated June 13, 1970 on conducting aeronautical geophysical measurements.

On January 30, 1971, the General Department of Geology transferred the task of aeronautical geophysical survey from Delegation 35 to the Department of Geophysics under Decision No. 26/QD-TC. The Aircraft Geophysics Team was established under the Department of Geophysics and Geology, taking the name of Team 65. Delegation 65 carried out the first aeronautical geophysical survey project “Aeronautical radiomagnetic survey in combination with Thanh Hoa area”. Thuy – Ba Vi, ratio 1:25,000”. The first technical staff to develop and implement the project include: Nguyen Quang Quy, Nguyen Thanh Chau, Tran Le, Mai Xuan Tuan, Ngo Minh An, Tran Huu Lich , Mai Xuan Thai, Pham Quang Phuc; Flight crew: Pham Tien Thuan, Le Ai Dich, Tran Phan Duc; Office team: Nguyen Xuan Son, Le Minh Phuc, Nguyen Huu Bac, Hoang Ba Ky, Tran Doan Hoe, La Thi Nghia, Nguyen Thi Lan….

By 1981, the 65th Division had carried out a number of geophysical flight plans such as: Aerial survey of 1:25,000 scale in East Ha Tinh, aerial radiological survey in Binh Tri Thien and Nghe Tinh regions.

In 1980, the United Nations sponsored Vietnam a system of electro-magnetic-spectral geophysical machines for aviation under the project of searching for groundwater for human life VIE/76/004.This is a geophysical equipment system. relatively modern aeronautical management, combining analog and digital recording, thereby allowing the application of computer-based document processing in the future. The technicians who have been trained in this period such as: Nguyen Van Hau, Nguyen Van Hop, Vu Van Danh, Nguyen Manh Quang, Nguyen Tuan Nam, Kieu Trung Thuy….Delegation 65 has implemented a number of flight plans. geophysics such as: 1:25,000 scale aerial survey in East Ha Tinh area, aerial radiomagnetic survey in Binh Tri Thien area, experiment on Canadian magneto-gamma-spectrum – aeronautical electrical equipment in Son Tay – Phu area Tho, surveying aviation electromagnetics in Ha Tuyen-Yen Bai-Hoa Binh region, surveying survey plans from aviation at the scale of 1:200,000 in southern provinces.

Due to many achievements in aeronautical geophysical surveys, in 1984, President of the State Council Truong Chinh awarded the third-class Labor Medal to officials and employees of Union 65 (Resolution No. 498 KT HĐNN dated May 18, 1984).

In the period 1982-1988, due to the need to search for radioactive ores for the purpose of nuclear energy development of the “Council for Mutual Economic Assistance of Socialist countries”, the General Department of Mining and Geology established a Geophysical Union. Aircraft 82 (Door 82) carried out survey flight plans from the gamma spectrum in the Da Nang – Quy Nhon region with the support of Soviet machinery and experts. The main officers of the 82nd Delegation included: Team leader Quach Kim Tru, deputy delegation Nguyen Van Bao, Doan Manh Tan, Quach Van Thuc, Vo Thanh Quynh…., geophysical engineers operating aviation machines such as: Dao Trieu Tuc, Tran Tien, Truong Cong Anh, Ho Hai, Vu Tuan Hung, Nguyen Van Lam…

In 1988, Aircraft Geophysics Enterprise was established under the Decision No. 650/M-DC dated October 4, 1988 of the General Department of Mining and Geology on the basis of merging 2 units, Team 65 and Team 82.

The current Aviation Geophysical Union is a unit that continues to inherit the tradition of the previous generation and perform aeronautical geophysical tasks for basic research, geological investigation, mineral search with 3 methods. : magnetic – gamma spectrum – aerogravity.

c/ Summary of achievements

Aviation geophysics has been applied in Vietnam since 1961. In 1964, the aerial survey flight at the scale of 1:200,000 was completed throughout the North of Vietnam. In 1983-1992, the flight was completed and linked with documents from the aviation division of South Vietnam to create a map of the field from Vietnam’s aviation at the scale of 1:500,000 (1995). This map was edited and published at a scale of 1:1,000,000 in 1998, it is valuable to use not only for geological, mineral, environmental, disaster,… but also for many Other fields such as communications, national security, etc.

Since 1982, began to apply flight technology to measure the combination of magneto-gamma spectroscopy for geological mapping and mineral search at the scale 1:25,000 and 1:50,000. To date, 18 flight projects from the gamma spectrum at 1:25,000 and 1:50,000 scale have been completed over an area of more than 95,000 square kilometers. The measurement results have collected data to establish field maps (magnetic field, gamma radiation field, field of radioactive elements K, U, Th). These data are then further processed-analyzed to establish geological structure maps, zoning and forecasting mineral prospects according to geophysical documents.

The geophysical flight technology of the Geophysical Union has been constantly innovating over the years. Before 1989, data was recorded using analog technology, flight navigation was done by taking photos and videos, and data processing and display of results were completely manual. From 1996 up to now, the above steps are all done digitally, always updated with world technology of the same period.

The results of the geophysical measurement flight, through the ground test, have detected many promising mineral areas for transfer of search and exploration. Many important mines have been discovered: Thach Khe iron (Ha Tinh), Na Rua, Na Lung, Boong Quang (Cao Bang); Khe Hoa – Khe Cao uranium (Quang Nam); fluorite Xuan Lanh (Phu Yen); gold (Son Hoa, Xa Lat, Xuan Son, Tra Bu, So Tang, Tay Hue…); magnesite Kong Queng, So Ro (Gia Lai), iron and copper-nickel in That Khe (Cao Bang), iron and lead-zinc in Cho Don (Bac Kan), Thuong Giap (Tuyen Quang); copper nickel Phan Thanh (Cao Bang) and many coastal ilmenite placer mines.

Currently, with new processing-analytic technology, the Geological Physics Federation is exploiting to improve the existing geophysical flight data, synthesizing with geological and mineral data on many structural zones– mineralogy in Vietnam. As a result, more potential areas of endogenous minerals have been identified and forecasted. When examining the ground, many new valuable mineral points were discovered such as gold in Khe Mang, Khe Nang (Ha Tinh), A Ngo (West Hue), Tra Doc (Quang Nam), Tien Cam (Quang Ngai)…

The achievements of the unit have contributed greatly, not only in geological, mineral, environmental, disaster investigation, … but also in many other fields such as communications, national security. room…for many consecutive years, the Union won the title of Excellent Labor Collective, …. Many individuals have won the titles of Hero of Labor, Emulation Soldier at branch and ministerial level…
