to all teachers and students:
at the invitation of chinese academy of sciences academician and president of lanzhou university, chunhua yan, on july 12, 2023, academician peizhen zhang, director of the academic committee of sun yat-sen university and seismologist, will visit our university to conduct the 2023 summer school lecture series titled "learning at lanzhou university: science and china." the details are as follows:
reporter: academician peizhen zhang
title: neotectonic and geomorphological evolution of the northeastern margin of the qinghai-tibet plateau
time: july 12, 2023, 15:30 (3:30 pm)
venue: western district, chengguan campus, student activity center lecture hall
reporter profile:
academician peizhen zhang, a seismologist, currently serves as the director of the academic committee at sun yat-sen university and is a member of the fifth academic and publishing work committee of the university. born in huaiyin county, henan province in december 1955, he graduated from changchun university of geology in 1979. he obtained his master's degree from the graduate school of the university of science and technology of china in 1982 and his doctoral degree from the massachusetts institute of technology in the united states in 1988. from 1988 to 1991, he conducted postdoctoral research at the university of nevada in the united states. in 1991, he returned to china and served as an associate researcher and researcher at the institute of geology, china earthquake administration. since 2015, he has been an academician at sun yat-sen university.
academician zhang's research focuses on the study of continental dynamics and the characteristics of strong earthquake activity through geological structural deformations at different time scales. through the analysis of gps data over a decade, he has revealed the present-day strain status of both extensional and shear deformations within the qinghai-tibet plateau and the compressional shortening in its surrounding areas. he has proposed a dynamic model that couples the movement of rigid blocks in mainland china with non-rigid continuous deformations. through his research on the structures of the neogene period spanning millions of years, he has obtained empirical evidence for low-rate and distributed deformations around the qinghai-tibet plateau. he has also discovered significant and widespread tectonic events during the late neogene period, which have had far-reaching effects. he has put forward a new perspective suggesting that substantial fluctuations between glacial and interglacial periods in global climate are responsible for a 2-4 million-year increase in sedimentation rates. through extensive field scientific investigations and in-depth laboratory research, academician zhang has made a series of new discoveries. these include the characterization of long recurrence intervals and interseismic deformation associated with the wenchuan earthquake, the rupture model of high-angle shovel-shaped thrust faults, and the causal model of multiple unit combinations. he has been honored with the national science and technology progress award (second class) three times and the natural science award (second class) once.
we welcome all teachers and students to actively attend!
