近期科学研究表明，地球深处的地幔中可能存在一个巨大的原始水储库。这一发现挑战了传统认为地球上的水主要来自彗星或小行星撞击的观点。研究人员通过分析来自地下600多公里深处的钻石包裹体，发现其中含有富含水的矿物——如林伍德石（ringwoodite），这种矿物在高压环境下能够储存大量水分。尽管这些水并非以液态形式存在，而是以羟基（OH⁻）的形式被锁在矿物晶格中，但其总量可能相当于地表海洋水量的数倍。这一储库被认为是地球形成初期就已存在的“原始水”，在地球演化过程中被封存在地幔过渡带（约410至660公里深度）。它不仅对理解地球水循环具有重要意义，还可能影响板块构造、火山活动甚至生命起源的研究。科学家推测，地幔中的水可通过火山喷发等方式缓慢释放到地表，参与长期的地质和气候过程。未来，通过更深入的地震波探测与实验室模拟，人类有望进一步揭示地球内部水的分布与动态机制。
Recent scientific studies suggest that a vast reservoir of primordial water may exist deep within Earth’s mantle. This discovery challenges the conventional view that Earth’s water was primarily delivered by comets or asteroid impacts. Researchers analyzed inclusions in diamonds originating from depths over 600 kilometers and found water-rich minerals such as ringwoodite, which can store significant amounts of water under high-pressure conditions. Although this water is not in liquid form but rather bound as hydroxyl (OH⁻) within the mineral lattice, its total volume could be several times that of all surface oceans combined.This reservoir is believed to be ‘primordial water’ trapped since Earth’s formation, preserved in the mantle transition zone (approximately 410–660 km deep). Its existence has profound implications for understanding Earth’s water cycle, plate tectonics, volcanic activity, and even the origins of life. Scientists hypothesize that water from the mantle may slowly return to the surface through volcanic eruptions, contributing to long-term geological and climatic processes. Future research using advanced seismic imaging and laboratory simulations may further unravel the distribution and dynamics of water deep within our planet.
