GEOPHYSICAL DIVISION
50 YEARS OF CONSTRUCTION AND DEVELOPMENT
During the 50 years of construction and development, the Geophysical division has overcome all difficulties, united by consensus, constantly strived and developed in all fields of work, achieved many results in production and research , has made worthy contributions to the geological investigation and mineral assessment of our country. The prominent areas of work of the Geophysical Division are
1. Aeronautical Geophysics Work
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 southern part of Vietnam’s aviation to create a map of the Vietnamese aviation field 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 not only for geological, mineral, environmental geology, geological hazards, etc. but also for many other fields such as communications, security and defense…
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). Thanks to the application of new processing technology, these data are then further processed – analyzed to establish geological structure maps, zoning maps to forecast mineral prospects according to geophysical documents. .
The geophysical flight technology of the Geophysical Division has been constantly innovating over the years. Before 1989, data was collected using analog recording 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); Phan Thanh field (Cao Bang) and many coastal ilmenite placer mines.
Currently, with new processing and analysis technology, the Federation of Geophysics is exploiting and improving 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 inspecting the ground, many new valuable mineral sites were discovered such as gold in Khe Mang (Ha Tinh), Khe Nang (Quang Binh), A Ngo (West Hue), Tra Doc (Quang Nam), Tien Cam (Quang Nam), Quang Ngai)….

In 1975, the South was completely liberated, the Federation of Geophysics and Geophysics was assigned the task of measuring and drawing up a gravity map of 1:500,000 scale of South Vietnam. From those two sources, a gravity map of the whole territory of Vietnam was established at the scale of 1:500,000 in 1985. In 2011, the Geological Physics Federation was assigned the task of additionally measuring the “empty areas”, combined gravity material at scale 1:100.000 – 1:50,000, complete gravity map at 1:500,000 scale and edited for publication.
Since the early 90s of the last century, the scale 1:50,000 and 1:100,000 gravimetric measurements have been widely applied, in combination with the aeronautical gamma spectrum measurement method, for mapping and mapping purposes. Geological map and mineral search in groups of 1:50,000 and 1:25,000 sheets. Gravity data has provided a lot of useful information about structure, fault, magma to support geological structure mapping, deep structure-tectonic research, and detect and classify hidden magma blocks. as a premise to search for minerals; detect and determine the structural parameters of the fault systems, the characteristic parameters of the transformation zones related to minerals. Up to now, the whole territory of Vietnam has 27 areas measured by gravity at the scale of 1:100,000 to 1:50,000 with a total area of approximately 85,000 km2..

Some typical results
Since its establishment in 1967, the Geophysical division has been assigned by the State to implement more than 300 projects, production reports and scientific research with territorial scale, survey rate and industrial complex. different recording technology.
According to the size of the territory, the rate of research, the above projects and reports can be classified into groups of tasks:
I. Small scale area geophysical research and investigation (<1:1,000,000 – 1:500,000);
II. Researching and investigating the area’s geophysics at the average rate (1:250,000 – 1:200,000);
III. Research and investigate the area geophysics at a large scale (1:100,000 – 1:25,000);
IV. Geophysical investigation, assessment, exploration (>1:25,000).
According to the technology and location of the recording, it can be divided into groups of geophysical methods: aeronautical, marine, terrestrial
According to the main investigation purpose, the service subjects can be divided into groups of geophysical methods of investigation: geology-minerals, environmental geology, geological hazards.
The products of these projects and reports are currently kept at two facilities: the Center for Geospatial Information and the Library of the Geophysical division.
This is an invaluable source of documents and information that not only has contributed to the cause of geological investigation and mineral search in the past period, but also has long-term meaning and continues to be processed. analysis in order to exploit for research, investigation and assessment of minerals, especially deep minerals in the new period as well as for other fields of the national economy.
The results of the geophysical research investigation small and medium scale areas have yielded a huge amount of data. These data are processed and built into maps according to each element and field composition with different scales. Up to now, most of Vietnam’s territory, on the mainland and in the sea and islands, has been surveyed, measured, and geophysically drawn at the scale of 1: 1,000,000 and in more detail, covering almost the entire area. with high homogeneity.

7. Some typical mines discovered from geophysical work
The results of geophysical work have directly or significantly contributed to the discovery of mines and ore bodies. Here are some typical mines:
Thach Khe iron mine, Ha Tinh was discovered directly through the results of flight measurements from 1: 200,000 of the northern territory of Vietnam in the 1960s of the last century. Total reserves and resources of grade B+C1+C2 have been calculated as 544 million tons of ore.
By radiometric method, a number of rock samples with high radioactive intensity have been detected, and since then, radioactive deposits – rare earths with large reserves have been found in Nam Xe, Phong Tho, Lai Chau.
Analysis of measurement results from aircraft gamma spectrum, combined with ground gravity data, have directly detected and predicted uranium prospects in the Nong Son lowland, which today has become the largest uranium mine in Vietnam.
Most other iron mines such as Bao Ha (Yen Bai), Lang Hit, Trai Cau (Thai Nguyen), etc.; Radioactive deposits, industrial-scale rare earths, titanium and ilmenite placer concentrations currently being exploited are all recorded on magnetic anomaly maps, aircraft gamma spectra and radioactive field maps. nature.
By stimulating polarization method in the early 80s of the last century, new deep-lying pyrite ore bodies with the largest reserves (about 1 million tons) were discovered in Giap Lai pyrite mine (Phu Tho).
Participating in exploration in Cho Don (Bac Kan), by Cra-E company (Australia) and the Vietnamese side, by means of field transfer and stimulated polarization to detect ore bodies at a depth of >100 m in conditions above are dense exploration and exploitation works.
Geophysical studies in the Sinh Quyen copper mine, and the endogenous copper-gold Ta Phoi-Lao Cai confirm that geophysical anomalies are very effective in detecting mineral bodies. Geophysically verified detection depth according to exploratory drilling documentation. The predicted depth of mineralization is >500m.
The magnetite iron ore mine of skarn origin in Boong Quang, Cao Bang province was discovered in 2002 when conducting a detailed examination of the mineral prospect area demarcated according to magnetic and gravity flight data. Here, when measuring geological mapping, searching for minerals at the scale of 1:50,000, no signs of ore were detected, including mineralization. In the same place was discovered copper-nickel mineralization deep down, which was confirmed according to the drilling results.
Kon Queng magnesite mine, Gia Lai province was also discovered in 2000 when examining in detail the potential mineral area identified according to the results of magnetic flight – gamma spectrum. This is a rich ore mine with huge reserves.
Iron, lead-zinc mines in Ban Duan, Na On, Bac Can province were discovered by a combination of methods of electricity, magnetism, gravity and transfer field. The results of determining the reserve are forecasted to be 470,047 tons of lead-zinc ore and 8,713,236 tons of iron ore.
