Abstract
Whether surficial carbonates can be carried into the Earth's lower mantle is key to global deep carbon cycles but remains poorly understood. New clues from magnesium and zinc isotopic systematics on rocks from deep-rooted mantle plumes are presented and discussed in this Perspective.
摘要
地表碳酸盐能否被带入地球下地幔是全球深部碳循环的关键，但目前仍知之甚少。本文从来自深部地幔柱岩石的镁和锌同位素系统中得出新线索并展开讨论。
