该项目将分析新生代深海沉积物中全相和矿物相的3He含量,以便在陆相和地外相之间分配3He收支平衡,并评估进入地球的惰性气体流量的变化。
英文摘要
This project will analyze Cenozoic deep sea sediments for their content of 3 He in fullereness and in mineral phases in order to partition the 3 He budget among terrestrial and extraterrestrial phases, and to assess the variation in extraterrestrial flux of noble gases to the planet.
