Prof.Zhang Wenyou(1909-1985)graduated in Beijing University in 1934.After graduation

he engaged in the research of basic geology and mineral resources under the direction of Prof.Li Siguang.In 1945-1947

he went to W Europe and N America on a tour of study and investigation

and in 1953

he again went to the Soviet Union on academic research.Through many years of geological research

he drew the essence of geomechanics and tranditional geology and creatively developed a new theory of fault-block tectonics.Based on this theory

he presided many major geological researches and made significant contributions in tectonics

and seismogeology

as well as in the geoexploration guidance of oil

gas

coal and other mineral resources.He led the compilation of the first tectonic map of China(1/5000000;1959)and the continental and marine tectonic map of China and its neighbouring regions(1/5000000;1983).His representative works—Guidance of Fault Block Tectonics—was written in his late years.
