Ge/Si record of marine biogenic opal

We have determined germanium/silicon ratios in purified diatoms and radiolarians from siliceous sediments in Holocene core tops, one late Pleistocene piston core, and four...本研究已测定采自全新世岩心表层（Holocene core tops）硅质沉积物、1根晚更新世活塞岩心（late Pleistocene piston core）沉积物以及4份（原文后续内容省略）硅质沉积物中的纯化硅藻（diatoms）与放射虫（radiolarians）的锗/硅比值。
