Geochemistry and Geochronology of Intraplate Lavas Recovered from the Arctic Ocean

This dataset presents new geochemical (major oxide, trace element, and Pb-Sr-Nd isotopic) information and Ar-Ar geochronology for intraplate lavas from the Arctic Ocean. Subaerial lavas were collected from Franz Josef land and submarine lavas were dredged from the Alpha/Mendeleev Ridges.

本数据集收录了北冰洋板内熔岩（intraplate lavas）的全新地球化学数据，涵盖主量氧化物、微量元素与铅-锶-钕同位素数据，同时提供氩-氩年代学（Ar-Ar geochronology）相关信息。研究团队采集了取自法兰士约瑟夫地群岛（Franz Josef Land）的陆上熔岩（subaerial lavas），并通过拖网采样获取了阿尔法/门捷列夫海岭（Alpha/Mendeleev Ridges）处的海底熔岩（submarine lavas）。
