摘要 月球的火山作用是月球的重要内生地质过程,反映了月球的内部演化。由爆发式火山作用形成的月球火山碎屑堆积物(LPD)代表了比月海玄武岩更深部的物质,是月球探测的优先目标之一。反射光谱是研究月球火山碎屑堆积物、在全球尺度上区分月球爆发式火山与溢流式火山的重要手段。文中选取29个已经确认的火山碎屑堆积物并结合模拟月球玻璃样品开展光谱学研究,建立了富玻璃的LPD光谱识别指标。根据模拟月球玻璃的铁钛含量与其1μm处吸收特征的关系比较了富玻璃火山碎屑堆积的相对铁钛含量,为今后提高月球火山碎屑堆积物的铁钛反演精度提供思路。研究结果表明,在这29个火山碎屑堆积中,Sulpicius Gallus、Gauss、Walther A、Birt E和Aristarchus是较为富玻璃的火山碎屑堆积。Aristarchus、Sulpicius Gallus和Birt E的钛含量低于Walther A、Gauss,Birt E,1μm左吸收肩偏短波方向,1μm吸收深度较浅,这可能因为Birt E具有异常低的Fe含量,或者其光学成熟度较高。鉴于火山碎屑堆积物重要意义,其是未来月球采样的较佳候选地区。 Lunar pyroclastic deposits(LPDs)originating from the explosive volcanism represent the deeper materials than the basalts in mare;they are the prior target for the lunar exploration.Reflectance spectroscopy is an important tool to study LPDs.We studied the spectrum of 29 LPDs which have been identified previously,established the distinguishing indicator of volcanic glass and proposed a new idea to compare the relative contents of FeO and TiO2 among the glass-rich LPDs.The result shows that Sulpicius Gallus,Gauss,Walther A,Birt E and Aristarchus are glass-rich LPDs.The titanium contents of Aristarchus,Sulpicius Gallus and Birt E are lower than those of Walther A and Gauss.The Birt E has the shallower absorption depth,and the left shoulder moves to shorter wavelength at 1μm band.It may be caused by the very low Fe2+content of Birt E or by its more mature material.
