On December 15-16, 2016, professor Qingsong LIU was invited to attend the annual meeting of Qingdao National Lab for Marine Science and Technology (QNLM) and deliver the branch report on “Sea Bottom Process, Resources and Exploration”. QNLM was officially approved by the Ministry of Science and Technology in December 2013, which was jointly constructed by the national ministries and commissions, Qingdao City and Shandong Province, which aims at conducting the fundamental research and cutting-edge technology research based on the national ocean development strategy.


Professor Qingsong LIU was selected as excellent scientist of the first group of “Aoshan Talents” of QNLM in 2016. Based on the “marine geological process and environmental function lab”, he conducts the cooperative research in terms of the marine geology and environmental evolution. On the research platform QNLM, the Department of Ocean Science and Engineering of SUSTC will develop in-depth cooperation with several relevant domestic ocean units to expand the influence of SUSTC.


At this Meeting, the report title of professor LIU is “Paleomagnetism Dating of East Asian Marginal Sea Sediment”. East Asian marginal sea sediment is a good medium to research the marine-continent exchange and marginal sea evolution, but it is a difficult science issue about how to accurately determine its age framework. Based on the detailed technological improvement of the rock magnetism and paleomagnetism measurement, the research team of professor LIU discusses the paleomagnetism dating method on the scales of millions of years, ten thousand years and one hundred years in detail. On the scale of millions of years, the impacts of the sulfide layer and later disturbance on the magnetic strata data shall be determined. On the scale of ten thousand years, with combination of the cyclic theory of the astronomic track and earth magnetic field intensity change characteristics, the chronology information may be provided effectively. On the scale of one hundred years, the secular variation characteristics of geomagnetic field may be used to determine the dating. Based the above-mentioned methods, this research team has achieved great progress in sediment dating in Bohai Sea, Yellow Sea, East China Sea, South China Sea and Yangtze River Delta of China.
