【摘要】：月表主要矿物的空间分布是研究月球起源及演化等科学问题的重要信息之一.以风暴洋地区为例,根据不同矿物光谱在可见光-近红外波段的吸收特征,使用印度M3(moon mineralogy mapper)数据,应用波谱特征拟合法(SFF)反演了火山口附近暗物质区域的单斜辉石、斜方辉石、橄榄石和尖晶石等铁镁质矿物的分布,反演结果显示:风暴洋地区提取的铁镁质矿物分布较集中,其中辉石含量较多,橄榄石和尖晶石含量相对较少.另外着重分析了橄榄石、尖晶石与周围矿物的关系及其地质意义.将提取结果与Lucey用于Clementine影像的光学模型填图结果进行对比显示,提取的橄榄石分布集中,但不存在大尺度的分布,这与本文的研究区域面积有关;就位置而言,二者具有较好的一致性.
[Abstract]:The spatial distribution of the main minerals on the lunar surface is one of the important information for the study of the origin and evolution of the moon. Taking the storm ocean area as an example, according to the absorption characteristics of different mineral spectra in the visible and near infrared bands, the Indian M3 moon mineralogy mapper data are used. The distribution of clinopyroxene, clinopyroxene, olivine and spinel in the dark matter region near the crater was inversed by the spectral characteristic fitting method. The inversion results show that the distribution of ferromagnesian minerals extracted from the storm ocean is relatively concentrated. Among them, the content of pyroxene is more, the content of olivine and spinel is relatively less. The relationship between spinel and surrounding minerals and its geological significance. The comparison between the extracted results and the optical model mapping results of Lucey used in Clementine image shows that the extracted olivine is concentrated in distribution, but there is no large-scale distribution. This is related to the area of the area studied in this paper, and there is a good consistency between them as far as the location is concerned.
