Li Siguang (1889-1971), Geologist

Li Siguang (1889-1971) was a member of the Chinese Academy of Sciences, a geologist and paleontologist. He was the founder of geomechanics and also a pioneer in China's paleontology and glaciology development. He awarded the National Natural Science Award. The asteroid with the international number 137039 was named after Li's name as "137039 Lisiguang".
Li Siguang's discovery of Quaternary glacial remains laid the foundation for the study of Quaternary geology, geography and climate, and contributed to the construction of hydrology and engineering in China. He created the Paleontological Fusulinid Classification Criteria, which accurately delineated the Carboniferous and Permian strata and was used by the international paleontological community to comprehensively study the sea level changes during the Carboniferous and Permian period and their relationship with the Earth's rotation. Li Siguang used mechanics to study the structure and movement patterns of the earth's crust and to delineate the sturctural systems of China and major regions of the world. He used geodynamic theory to guide the search for energy sources such as coal, oil, uranium and geothermal heat, and to prevent and control natural disasters.

Li Siguang Geological Science Award
This is a science award established in 1989 to honour Li Siguang's outstanding achievement and his patriotism, as well as to encourage geoscientists to contribute to the socialist modernisation and the advancement of science and technology. The Li Siguang Geological Science Award consists of four awards: The Li Siguang Geological Science Field Geologist Award, The Li Siguang Geological Science Research Award, The Li Siguang Geological Science Teacher of Geology Award and the The Li Siguang Geological Science Honor Award.
