法国格列诺布尔大学IRlGM研究所G.Poupinet和B.de Voogd根据地震资料说明新、老大陆板块的上地幔结构的差异。他确定,P波以垂直方向通过太古代地质的时间比通过古生代地台的时间要快1.2秒,这证明若化学成
G. Poupinet and B. de Voogd at the IRIGM Institute at the University of Glète-Gloucestershire in France described the differences in the structure of the upper mantle between the new and old continental plates based on seismic data. He determined that the P-wave travels through the Archean geology in the vertical direction faster than the passage through the Paleozoic platform for 1.2 seconds, demonstrating that if the chemical
