Li Guangxing s main research results, what are Li Siguang s research results?

There are a large number of remnants of Quaternary glacial activity in the Yangtze River basin.

1.for China's atomic and hydrogen bombs.

The success of the development within the room has made outstanding contributions.

2.Using the study of mechanics on the movement of the earth's crust and the law of mineral distribution, the concepts of "geomechanics" and "tectonic system" were created. **The three subsidence zones of the New China tectonic system contain oil, and the discovery of Daqing Oilfield, Dagang Oilfield, Shengli Oilfield, North China Oilfield and other oilfields confirms it**.

3.In his early years, he had excellent research on the fossils of the Flyidae family and their stratigraphic significance. The study of fossils and their stratigraphic significance in northern China is the earliest study of the Carboniferous Permian in China.

The character "" created by him, which is used to translate fusulinid (a long-extinct foraminifera belonging to the protozoa), is used by the Chinese paleontological community.

4.The theory of the existence of Quaternary glaciers in East China was proposed.

5.Forecast: Li Siguang believes that it can be predicted.

China is a country with many people, and Li Siguang has done a lot of pioneering work for geology and forecasting; In his later years, Li Siguang also did a lot of work for the development and utilization of geothermal energy in China, and created a forecasting method that combines active tectonic research and in-situ stress observation, and the "astronomical, geological and paleontological data" published in his later years had a profound impact on the advocacy of China's interdisciplinary disciplines, and made great contributions to the development of China's geological education, geological science and geology.

Femtosecond detection found plagiarism in 1953, Li attacked.

Siguang proposed the "New Huaxia Construction System." In 1954, he personally organized a team to carry out oil surveys in Songliao Pingzhiyuan and North China Pingdaoyuan, and after several years of hard work, he successively discovered Daqing Oilfield, Shengli Oilfield, Dagang Oilfield and ......Then, Li Siguang and other geologists worked together to make China quickly find tungsten, chromium, uranium, diamond, coal and rare metal deposits, and made great achievements in the development of geothermal and groundwater, and the study of Quaternary glaciers.

Li Siguang's research covers a wide range of subjects, and he has made great achievements in paleontology and glaciology. His research on Quaternary glacial relics overturned the previous assertion that "there are no Quaternary glaciers in China". In the study of geological theory, the most important work was the creation of geomechanics.

He used the perspective of mechanics to study the movement of the earth's crust and the distribution of minerals, and regarded various structures as the result of in-situ stress. Regarding the geological characteristics of eastern China, Li Siguang used the theoretical analysis of geomechanics to analyze the three subsidence zones of the New China tectonic system, which has broad prospects for oil searching, thus rejecting the view that "China is poor in oil".

1. "Li Siguang's research results" refer to the relics of a large number of Quaternary glacial activities in the Yangtze River Basin.

2. Li Siguang founded geomechanics and made important contributions to the development of China's petroleum industry; In the early years, he had excellent research on the fossils of the Flyidae family and their stratigraphic significance, proposed the existence of Quaternary glaciers in eastern China, and established a new marginal discipline"Geomechanics"with"Tectonic system"concept, established"Tectonic system"the concept that created the school of geomechanics; This paper proposes the understanding of the broad prospect of oil prospecting in the three subsidence zones of the New China tectonic system, and creates a forecasting method that combines active tectonic research and in-situ stress observation.

In the 50s of the 20th century, under the leadership of Minister Li Siguang and through the continuous theoretical exploration and practice of China's famous geologists such as Huang Jiqing and Xie Jiarong, it was affirmed that eastern China, especially the Songliao Basin in Northeast China, has good oil storage conditions. After listening carefully to the report, he supported the views of the Ministry of Geology, and according to the suggestions of the Ministry of Geology and Li Siguang, a large-scale oil survey was started in the Songliao Plain and the North China Plain. In 1956, under the auspices of Li Siguang, the oil survey and exploration work in a very short period of time successively discovered Daqing, Shengli, Dagang, North China, Jianghan and other oil fields, and established immortal contributions to China's petroleum industry.

From the late 50s to the 60s, the exploration department successively found the Daqing Oilfield, Dagang Oilfield, Shengli Oilfield, North China Oilfield and other large oil fields, which made the rolling oil emerge when the country was in urgent need of energy. In this way, not only did they take off the hat of "China's poor oil", but also made the theory of terrestrial oil production put forward by the Chinese and the theory of geomechanics founded by Li Siguang the most powerful proof.

Li Siguang's research results: Dali Ice Age Yumu Ice Age: about 70,000 10,000 years ago Lushan Ice Age Rees Ice Age:

About 370,000 240,000 years ago Dagu Ice Age Minde Ice Age: about 800,000 680,000 years ago Poyang Ice Age Qunzhi Ice Age: about 1,200,000 900,000 years ago.

He has made outstanding contributions to China's "poor oil" hat, China's atomic bomb, the establishment of geomechanics theory, and the successful development of China's hydrogen bomb.

Li Siguang (1889-1971) was a Chinese geologist and the founder of geomechanics. He founded geomechanics in the 20s of this century and made great contributions to geological theory. He used the viewpoint of mechanics to study the phenomenon of crustal movement, regarded various tectonic traces as the result of in-situ stress activities, established the basic concept of geomechanics of "tectonic system", provided a new method for exploring geological natural phenomena, opened up a new way for the study of crustal motion laws, created a new situation in geological science, and enjoyed a high reputation in the world.

His theories have made great contributions to China's oil exploration. For example, he used geomechanics to analyze the characteristics of geological structure in eastern China, and believed that the three subsidence zones of the New China tectonic system had a broad prospect for oil searching, which theoretically denied the theory of "China's oil poverty". The successive discoveries of Daqing, Shengli, Dagang and other oil fields confirmed his scientific foresight.

In terms of geological work, he emphasized that on the basis of studying the activity of geological structures, the changes of in-situ stress were observed, and the direction was pointed out for the realization of the first forecast. In addition, as early as the early 20s, Li Siguang visited the foothills of the Taihang Mountains, the Datong Basin, the Lushan Mountains and the Huangshan Mountains in China, and successively discovered the remains of Quaternary glaciers, which overturned the erroneous conclusion of many international glaciological authorities that there are no Quaternary glaciers in China. Li Siguang has been engaged in the research of paleontology, glaciology and geomechanics for a long time, and has made outstanding contributions in the identification of paleontological fossils, the discovery of Quaternary glaciers in China, and the establishment of geomechanics.

He is the author of the book "Concepts of Geomechanics", which argues that the deformation of rocks in the movement of the earth's crust is due to the action of in-situ stress. In July 1947, he represented China at the 18th International Geological Congress, and for the first time applied the geomechanical theory he founded, and gave an academic report entitled "The Origin of the New China Sea", which aroused strong repercussions. Since then, geomechanics, a new discipline founded by the Chinese, has officially gone down in history.

Li Siguang returned to China from England in 1920 and spent his life studying earth science. He was studious, practical, and knowledgeable, and achieved outstanding achievements in many areas, the most important of which was the creation of geomechanics with worldwide influence. Using this theory, Li Siguang put forward his own unique insights on the analysis of modern crustal movements, the exploration of mineral resources, and the forecast, which have withstood the test of practice.

In addition, he was also the discoverer of the Quaternary glaciers in China, and also made special contributions to the study of fossils.
