Understanding the mineralogy of the Earth's interior is a prerequisite for unravelling the evolution and dynamics of our planet. Here, we conducted high pressure-temperature experiments mimicking the conditions of the deep lower mantle（DLM, 1800–2890 km in depth） and observed surprising mineralogical transformations in the presence of water. Ferropericlase,（Mg,Fe）O, which is the most abundant oxide mineral in Earth, reacts with H;2;O to form a previously unknown（Mg,Fe）O;2;H;x;（x ≤ 1）phase. The（Mg,Fe）O;2;H;x;has a pyrite structure and it coexists with the dominant silicate phases,bridgmanite and post-perovskite. Depending on Mg content and geotherm temperatures, the transformation may occur at 1800 km for(Mg;0.6;Fe;0.4;)O or beyond 2300 km for(Mg;0.7;Fe;0.3;)O. The（Mg,Fe）O;2;H;x;is an oxygen excess phase that stores an excessive amount of oxygen beyond the charge balance of maximum cation valences(Mg;2+;, Fe;3+;and H;+;). This important phase has a number of far-reaching implications including extreme redox inhomogeneity, deep-oxygen reservoirs in the DLM and an internal source for modulating oxygen in the atmosphere.

在甘肃陇东地区相关志书类中,明代嘉靖年间乐蟠人侍郎韩鼎编撰《庆阳府志》载:“婚嫁,用鼓乐迎至女家”以及“丧礼悉宗古制……用鼓乐遂迎诸客。”明代编纂、清代续修的《平凉府志》云:“岁除日多嫁娶,祭祀祖妣,男女以序献酬四拜,爆竹鼓吹欢呼终夜。”今日的甘肃庆阳唢呐音乐,正是这些文献中的“鼓吹”“鼓乐”。据多名艺人介绍并参照相关资料可推知,目前甘肃庆阳地区的唢呐艺人约有千名以上,“生也唢呐、死也唢呐”仍然是这一方土地人民两种民俗用乐的典型形式。那传人状况究竟如何?传承又有何特点?
