• Academician Chen Yuchuan has insisted to do field work and research in Xinjiang for more than 40 years, since he did iron research in Xinjiang in 1977. He has made great contributions to the metallogenic theoretical innovation and geological prospecting main breakthrough in Xinjiang. Under his leading and guidance, there are four monographic studies on metallogenic series in Xinjiang carried out, and one map on metallogenic series of mineral deposits in the Xinjiang Uygur Autonomous Region at 1:1 500 000 published. The successful completion of twice metallogenic zoning and mineral resource potential assessment on solid minerals in Xinjiang has urged the leading level in the whole nation. In the “305” national key project of science and technology, he leaded us to play a key role, to host four major researches and to publish 6 academic monographs with one first prize on science and technology progress in Xinjiang Uygur Autonomous Region. He also played a key role in the new round prospecting for solid minerals, new round survey on land and resources, Xinjiang 358 special project in 21th century, special project for deep prospecting in Xinjiang and central special project for Xinjiang geology and exploration. His work has promoted the geological prospecting main breakthrough in Xinjiang and has made outstanding contributions for Xinjiang to become one key base for important strategic resources.
