Ammonium phyllosilicates have been identified on the dwarf planet Ceres, thanks to infrared telescopic and orbital data from the Dawn mission, by means of the 3.06 μm spectral feature. Nevertheless, it is not known which ammonium‐bearing phyllosilicate species are present, nor the thermal processing they underwent throughout Ceres history. Identifying the NH₄⁺‐hosting mineral species is important for deciphering Ceres’ surface mineralogy, which provides a link to its interior and putative different evolutionary pathways. Ammoniated species can have formed in the presence of water/ammonia‐rich fluids in different conditions in the interior of the planet; in case of an exogenous outer Solar System origin, they can have undergone heating at depth.

NH4-苯基硅酸盐的高温VIS-IR光谱

借助Dawn任务的红外望远镜和轨道数据，借助3.06μm光谱特征，已经在矮行星Ceres上发现了层状硅酸铵。但是，目前尚不清楚存在哪种含铵的页硅酸盐种类，也不清楚它们在整个谷神星的历史中都经历过热处理。识别含有NH ₄ ^+的矿物种类对于破译谷神星的表面矿物学很重要，它提供了与其内部和假定的不同进化途径的联系。在行星内部，在不同条件下，存在水/富氨流体的情况下会形成氨化物种。在外源太阳系起源的情况下，它们可能已经进行了深层加热。
