1952, when the national department was adjusted, she became a professor at Beijing Institute of Geology and served as the director of the Department of Geology and Mineral Resources, leading and cultivating a large number of talents urgently needed by the country and playing an important role in the front line of geological exploration. In the early days of People's Republic of China (PRC). In order to change the oil poverty in China, the school urgently needs to offer courses related to oil exploration. Professor Chi Jishang changed his major and became the director of the petroleum teaching and research section. He opened the first new class of sedimentary petrology in China, and also instructed He Jingyu, a teaching assistant, to set up practical experimental courses such as salt content analysis to meet the needs of petroleum exploration in northwest China. 1954 65438+In February, he served as the deputy director of the geological exploration department of combustible minerals, assisted Professor Wang Hongzhen, director of the department, to lead and train a large number of talents in petroleum and coalfield geological exploration. From June 65438 to September 0957, he served as the deputy director of the Department of Geological Survey and Prospecting, assisted Professor Yang Zunyi, the director of the department, to preside over teaching and scientific research, and devoted a lot of efforts to teacher training. Over the years, she has taught such courses as sedimentary petrology, metamorphic petrology, crystal optics and rock-forming minerals, magmatic petrology, tectonic petrology and Fedoroff method. , and compiled a variety of teaching materials such as Petrology and Sedimentary Petrology. In 1958, she compiled the first unified teaching material of magmatic petrology in China with reference to advanced foreign theories and methods, and combined with a large number of domestic actual data, and then compiled a concise course of Fedoroff's methods in 1962.
1956 and 1957, she participated in the Qilian Mountain comprehensive geological exploration team jointly established by China and the Soviet Union, and crossed the Qilian Mountain twice to investigate the geological structure and minerals. She instructed her assistant Liu Baojun to complete the topographic and tectonic lithofacies map of Chaka area in Qinghai. This picture was later adopted by colleges and universities and incorporated into the course of magmatic petrology. The working conditions in Qilian Mountains are very difficult. Get off work at 9: 00 in the morning and go back to the tent at night 10. 1September, 957, Liu Baojun, the assistant, could not walk because of his cold feet. She is the only one who finished the route and insisted on finishing the task. During the period of 1958, more than 200 teachers and students of Beijing Institute of Geology participated in the geological survey and general survey of prospecting work in the central and western Shandong1∶ 200,000 area, with Chi Ji as the team leader and technical chief. Within four years, the team submitted 14 geological maps (covering an area of 896 million square kilometers) and map reports, all of which were officially published by the state, laying a foundation for prospecting and exploration in the west of Mu Yi fault. In particular, the team first recognized the existence of the Mu Yi fault zone in the eastern part of China, which is of great significance for guiding the prospecting and tectonic theory.
In the early 1960s, she led a special research team to study the Yanshan granite in Badaling area, Xishan, Beijing. 1962, she published the article "Nankou Granite in the West Section of Yanshan Mountain (mainly involving magmatic differentiation, assimilation and mineralization specificity)", which is the first time that a large magmatic complex has been studied and divided in different stages in China. This paper discusses the geochemical characteristics and mineralization specificity of Nankou granite, and discusses the causes of the similarities and differences of granite in this area for the first time. This paper set a model for domestic petrography at that time in research ideas, methods and theories, and was at an advanced level in the world.
China's economic development and construction urgently need diamond resources. 1965, the Ministry of Geology organized the Academy of Geological Sciences, Beijing Institute of Geology and Shandong 809 Team to form the Shandong 6 13 scientific research team, with Chi Ji as the technical director. Through more than a year's efforts, the first batch of Shandong kimberlite research results were completed, and the collective prize was won at the National Science Conference from 65438 to 0978.
In the late 1960s, she first discovered magmatic apatite deposits in alkaline ultramafic rocks in North China in Kuancheng, Hebei Province. This discovery opens up a new prospect for finding similar deposits in the north and reversing the situation of South-to-North Water Diversion Project in China.
In the face of the adversity during the Cultural Revolution, she still participated in the training courses organized by the reform team in the geological teams of Hebei, Jiangxi and Hubei provinces, helped to set up the laboratory, and went to Hubei, Liaoning, Henan and other provinces to conduct field visits to kimberlite and similar rocks, and continued to contribute to the search for diamond resources under extremely difficult conditions.
From 65438 to 0975, Wuhan Institute of Geology was founded. Chi Jishang served as deputy director and director of the Department of Geology and executive vice president of Wuhan Institute of Geology. She presided over the "July 21 University" jointly organized with Hubei Bureau of Geology and Mineral Resources, resisted the ultra-left practice of "focusing on stage struggle", organized teachers to make their own textbooks and give lectures carefully, and trained 100 junior college students majoring in geology and geochemistry for the geological team. In the process of school relocation, she devoted herself to this work. Under the condition of unstable personnel and lack of equipment and teaching materials, she guided the teaching work of the whole hospital to the right track step by step and re-trained a batch of college graduates. After the Third Plenary Session of the Eleventh Central Committee of the Party, the spring of science came. She presided over the application for a loan from the World Bank and established a testing center with modern equipment and high-level research capabilities. She made great efforts to build a teaching staff and presided over the selection of a group of teachers to go abroad for further study. At the same time, she has been insisting on teaching petrography, compiling and publishing textbooks and monographs such as Tectonic Petrology and Fedoroff's Law.
1980 was elected as an academician of China Academy of Sciences.
1981-1984, she led more than 30 teachers and students, aimed at the international frontier disciplines, and undertook the research on the key topic of the Ministry of Geology and Minerals, "Cenozoic volcanism, deep xenoliths and the relationship between mineralization and ore sources in eastern China". After several years' efforts, he presided over the scientific research on Cenozoic basalt and upper mantle (including kimberlite) in eastern China, and published a monograph. This book systematically discusses the geological, petrological, mineralogical and geochemical characteristics of Cenozoic basalts and upper mantle rocks in eastern China, deeply discusses the related problems of Cenozoic continental rift magmatism and deep processes in eastern China, and systematically summarizes the characteristics and prospecting direction of kimberlite in China. The research method of petrology is exemplary, with outstanding pioneering, reaching the advanced level at home and abroad, and won the first prize of 1989 scientific and technological achievements of the Ministry of Geology and Mineral Resources.
She also presided over the National Natural Science Foundation's scientific research project "Petrological study on phosphorus-rich alkaline, basic and ultrabasic rocks, carbonate rocks and tectonic magmas in some areas of North China" and "Study on prediction theory and method of diamond primary deposits in North China platform".
She directed the completion of the science and technology fund project of the State Education Commission, "Petrology of eclogite and ultrabasic rocks in Rizhao-Junan area, Shandong Province and the possibility of finding kimberlite and diamond primary deposits". She made many academic reports at the symposium on "Kimberlite and Diamond Prospecting" held by the Ministry of Geology and Mineral Resources, systematically introduced the research results of the research group, and analyzed the international research level and development trend of Kimberlite at that time, making new contributions to the study of Kimberlite and diamond prospecting in China. For decades, Chi Ji has been engaged in various fields of petrology and many disciplines of geology, and her field work has covered more than 20 provinces (autonomous regions) including Tibet.
She has done a lot of positive and fruitful work for developing friendship and cooperation between Chinese and foreign scientists. She is the representative of China in the Executive Board of the International Geological Correlation Program (IGCP) (1979- 1982) under UNESCO and the International Union of Geosciences, and has attended international conferences in Washington and Paris. She received many foreign scholars to visit China, and cooperated with famous geologists in the United States, the former Soviet Union and Australia, such as Professor P.J.Wyllie and I.S.E? Professor carmichael, Professor Nisumula, Professor D.H. Green and Professor ви Lebedinski all have friendly exchanges and academic exchanges.
