Abstract > The Visible and Infrared Spectrometer ( <fc>VIR</fc> ) instrument on the Dawn mission observed Ceres’s surface at different spatial resolutions, revealing a nearly uniform global distribution of surface mineralogy. Clearly, Ceres experienced extensive water‐related processes and chemical differentiation. The surface is mainly composed of a dark component (carbon, magnetite?), Mg‐phyllosilicates, ammoniated clays, carbonates, and salts. The observed species suggest endogenous, global‐scale aqueous alteration. While mostly uniform at regional scale, Ceres’s surface shows small localized areas with different species and/or variations in abundances. Few local exposures of water ice are seen, especially at higher latitudes. Sodium carbonates have been identified in several areas on the surface, notably in Occator bright faculae. Organic matter has also been discovered in several places, most conspicuously in a large area close to the Ernutet crater. The observed mineralogies, with the presence of ammoniated species and sodium salts, have a strong resemblance to materials found on other bodies of the outer solar system, such as Enceladus. This poses some questions about the original material from which Ceres accreted, suggesting a colder environment for such material with respect to Ceres’s present position. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><abstract xmlns =“http://www.wiley.com/namespaces/wiley”type =“main”xml：id =“maps13104-abs-0001”xml：lang =“en”> <标题类型=“main”>抽象</ title> > 可见光和红外光谱仪（ <FC> Vir </ Fc> ）在不同的空间分辨率下观察CERES表面的仪器，揭示了表面矿物学的几乎均匀的全球分布。显然，CERES经历了广泛的水相关方法和化学分化。该表面主要由深组分（碳，磁铁矿→），Mg-碱基，氨化粘土，碳酸盐和盐组成。观察到的物种表明内源性，全球范围水性改变。虽然在区域规模大多是均匀的阶段，但CERES的表面显示出具有不同物种和/或丰富的变化的小局部区域。看到少数局部曝光的水冰，特别是在更高的纬度。已经在表面上的几个区域中鉴定了碳酸钠，特别是在偶然的亮点上。在几个地方也发现了有机物质，最明显地在靠近Ennutet火山口的大面积中。观察到的矿物学杂志具有氨化物质和钠盐的存在，与外太阳系统的其他体内的材料具有很强的相似性，例如Enceladus。这造成了关于CERES凸起的原始材料的一些问题，这表明关于这种材料的较冷环境，关于CERES的现在位置。 </ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-24922/'>《Meteoritics & planetary science》</a> <b style="margin: 0 2px;">|</b><span>2018年第9期</span><b style="margin: 0 2px;">|</b><span>共22页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=D Sanctis M.
