Events----INSTITUTE OF GEOLOGY AND GEOPHYSICS, CHINESE ACADEMY OF SCIENCES

During April 26 - 30, the Education Department of the Institute of Geology and Geophysics, CAS (IGGCAS) organized a geological field excursion to Jixian, Tianjin, Miyun, and Beijing for graduate students at the institute. A total of 44 doctoral and master graduate students participated in this trip, which included four doctoral students from Mongolia, Ghana and France, whose majors cover the three first-grade disciplines of geology, geophysics, geological resources and engineering as well as two second-grade disciplines of marine geology. During the trip, aimed at teaching the students necessary field skills, Deputy Director Wu Fuyuan, Chu Xuelei, Chen Daizhao, Lin Wei and Peng Peng showed the students to geological features of the areas and key observations for their interpretation. The trip focused on two main geological regions of interest.

(1) To investigate the Early Precambrian geology in Miyun and the typical sedimentary profiles of Jixian in the late Early Proterozoic to Mesoproterozoic (1800-1000 Ma); to understand the early Precambrian geological evolution in North China Craton as well as the Meso-neoproterozoic major geological events and the early environments of Earth, and consider the formation and failure mechanisms of North China Craton.

(2) To investigate the metamorphic core complexes of Yunmeng Mountains and the volcanic rocks of Sihai Basin; to understand the detachment fault time and spatial distribution characteristics through interpreting deformation performance and thermal chronology research results from different layers of rocks; to explain the tectonic analyses on different tectonic sections of complexes in Yunmeng Mountains; to learn how to identify multiphase tectonic events from the overall structural frame; and to consider the relation of the large-scale shallow tectonic deformation and magma activity in the North China Craton since the Mesozoic with the deep failure process of North China Craton.

A concluding seminar of postgraduate geological field trip was held on April 29, where Deputy Director Wu Fuyuan summarized the purpose and importance of postgraduate geological field trip in detail. He engaged with the graduate students and discussed key parts of the organization and arrangement of such a geological trip. The students expressed that the geological field trip could be used not only for understanding and mastering relevant geological knowledge as well as field geological work methods and skills, but also strengthening the mutual communication and understanding between the students with different professional backgrounds, so as to enrich the cultural life of graduate students in the Institute.
