Important scientific research achievements of the year
Practical application and demonstration of fixed-wing time-domain airborne electromagnetic measurement system. In cooperation with Hafei Aircraft Design and Research Institute, Hafei Aviation Maintenance Company, China Longfei General Aviation Co., Ltd. and the flight test crew, more than ten technical problems of flight test were solved, 13 flights were carried out, 32 adjusted flight test subjects were completed in three stages, and 2.3GB of original data were collected. Full-state integrated debugging test flight was successful.
Engineering development of deep three-dimensional electromagnetic detection technology. This project is a major national scientific instrument and equipment development project. The prototype of three-dimensional electromagnetic detection system has been successfully developed. The field tests of the three-dimensional multifunctional electromagnetic prototype system, transient electromagnetic prototype system and inductive sensor show that the measurement parameters among the instruments are consistent and reliable, the receiver can work continuously and stably, and the transmitter can realize the power supply of the highest voltage1500 V. At the same time, the three-dimensional observation experiments and applications of various methods and devices are carried out in the mining area by using the developed prototype system. The comparison between the obtained survey information and the existing exploration results in the mining area shows that the three-dimensional survey results reflect the three-dimensional spatial distribution characteristics of the deposit, and the three-dimensional geophysical exploration is initially realized.
Integrate the results of regional geophysical survey and research on methods and technologies, and carry out regional geochemical survey of metallogenic belt. The methods and techniques urgently needed for regional geophysical exploration have been developed, and the regional geophysical survey areas of132,000 square kilometers and1:50,000 square kilometers have been completed, which has increased the national1:250,000 regional gravity survey from 49.6% to 5 1.0%. The basic geophysical map of key metallogenic belts has been compiled, and the comprehensive regional geophysical research of related key metallogenic belts has been completed, such as the comprehensive research of Southwest Sanjiang, and the structural units and fault structures have been divided by using the latest regional gravity data. The methods and techniques urgently needed for regional geochemical exploration have been developed, and 90. 15% of regional geochemical exploration has been completed.
Study on determination of rare elements by melting sample preparation -la-HR-ICP-ms method. In view of the fact that the composition of carrier gas injected into LA-HR-ICP-MS has a direct impact on the signal sensitivity, a helium injection device was added to the carrier gas system, and the mixed gas of helium and argon was used as the carrier gas for sample determination, and the flow rate of the mixed gas was optimized. Under the optimum mixing conditions, the RF power, auxiliary gas flow rate and injection depth were optimized respectively, and the optimum instrument conditions of HR-ICPMS were obtained.
The first flight of time domain special plane B-3855 was successful.
Three-dimensional multifunctional electromagnetic receiver and sensor
Three-component transient electromagnetic receiver and sensor
Complete the establishment of geochemical reference values of Chinese mainland 8 1 index (including 76 elements). An accurate analysis system of total elements in the crust has been developed, including 76 elements and 5 geochemical indicators, all of which have reached the international leading level. For the first time, the national soil geochemical reference map with the index of 8 1, the rock geochemical reference map weighted by the exposed area of strata and 76 elemental geochemical maps of magmatic rocks were made. A number of new prospecting prospects such as uranium, rare earth, copper and gold have been discovered, especially the uncovered basin sandstone-type uranium deposits and unanalyzed rare earth element deposits in the past regional geochemical exploration scanning; Geochemical standards for eight heavy metal elements such as cadmium, mercury, arsenic, lead, chromium, copper, nickel and zinc, and radioactive elements such as uranium, thorium and potassium have been established.
-The global geochemical information platform "Chemical Earth" was initially established. The "Chemical Earth" database and geochemical graphic display model are established, which realizes the management of multi-scale massive geochemical data and graphics, can display geochemical maps of different scales, and has the functions of interactive query between graphics and data, sampling information query and so on. Develop "Chemical Earth" software with completely independent intellectual property rights (abbreviated as "Chemical Earth") V1.0; A national database has been established to explore all elements in the earth's crust. Some geochemical mapping data from Europe and America were collected and successfully applied to "Chemical Earth".
