Most minerals of Earth's upper mantle contain small amounts of hydrogen, structurally bound as hydroxyl (OH). The OH concentration in each mineral species is variable, in some cases reflecting the geological environment of mineral formation. Of the major mantle minerals, pyroxenes are the most hydrous, typically containing approximately 200 to 500 parts per million H(2)O by weight, and probably dominate the water budget and hydrogen geochemistry of mantle rocks that do not contain a hydrous phase. Garnets and olivines commonly contain approximately 1 to 50 parts per million. Nominally anhydrous minerals constitute a significant reservoir for mantle hydrogen, possibly accommodating all water in the depleted mantle and providing a possible mechanism to recycle water from Earth's surface into the deep mantle.
地球上地幔的大多数矿物都含有少量以羟基（OH）形式结构结合的氢。每种矿物中的OH浓度各不相同，在某些情况下反映了矿物形成的地质环境。在地幔主要矿物中，辉石的含水量最高，通常按重量计含有约百万分之200至500的H₂O，并且可能在不含水相的地幔岩石的水收支和氢地球化学中占主导地位。石榴石和橄榄石通常含有约百万分之一至50。名义上的无水矿物构成了地幔氢的一个重要储存库，可能容纳了亏损地幔中的所有水，并提供了一种将地球表面的水再循环到深部地幔的可能机制。
