The contents of the newspaper handwritten by geologist Li Siguang.

The contents of the newspaper handwritten by geologist Li Siguang are as follows:

1, Li Siguang, China geologist, native of Huanggang, Hubei Province, formerly known as Li.

2. Li Siguang studied geology at the University of Birmingham, England, and obtained a master's degree 19 19.

3. After returning to China, Li Siguang taught in many universities and made many important achievements in geological research.

4. Li Siguang's research achievements on Odonata fossils broke the chaotic situation of international classification of Odonata at that time.

5. Li Siguang has also made great contributions in the field of Quaternary glaciology. He overthrew the wrong theory that there was no Quaternary glaciology in China at that time.

6. Li Siguang's innovative research in the field of geology has made important contributions to the development of modern geology in China.

7. The geomechanics theory put forward by Li Siguang provides important theoretical support for oil exploration and development in China.

8. After the founding of People's Republic of China (PRC), Li Siguang held many senior positions, including vice president of China Academy of Sciences and Minister of Geology of China.

9. Li Siguang paid attention to practice and investigation in scientific research, and opposed theory on paper, which had an important impact on scientific research and economic development in China.

10, Li Siguang studied hard all his life. In his later years, he wrote these four characters in his study: diligence and innovation. These four words reflect his spirit of pursuing scientific truth and his determination to keep exploring.

Li Siguang's contribution:

Li Siguang founded geomechanics, which made great contribution to the development of China petroleum industry. In the early years, the Odonata fossils and their stratigraphic stratification were studied exquisitely, and it was pointed out that there were Quaternary glaciers in eastern China.

The concepts of "geomechanics" and "tectonic system" were established, and the geomechanics school was founded. It is pointed out that the three subsidence zones of the new Cathaysian tectonic system have broad prospects for oil exploration, and a way to predict earthquakes by combining active tectonic research with in-situ stress observation is created.
