Analysis Of Spectral Characteristics Of Lunar Soil And Quantitative Inversion Of Minerals Information

The exploration of the lunar surface material composition is an important part of lunar exploration. Inversion of the lunar information has important significance, especially in the lunar exploration, lunar landing and lunar resources development. It is also the important parameters to study the origin and evolution of lunar. In this paper, basing on the analysis of the lunar soil spectra, some of the domestic and international data has been preprocess and mineral information extract and coprehensively analyze for the multi-source information of the Oceanus Procellarum - Mare Imbrium region, and some craters. The main contents of this paper and the results are as follows:(1)The analysis of some minerals and rocks of the lunar. Spectral library of lunar samples in the U. S. RELAB, theoretical simulation data, and the spectra of the same minerals in the USGS spectral library. The lunar spectra has been analyzed by spectral theory and the effect of each component to the mixed spectra has been analyzed, too. The spectra of the minerals are different from the earth's as it's drying reducing environment. the absorption features of the lunar minerals mainly lead by the divalent iron and titanium elements, but the hydroxyl or hydrated ions. That the maturity is affected by the solar wind, cosmic rays results in the spectra of the lunar soil lower, flat, and less features.(2)Determination the clinopyroxenes, ortho-pyroxene, plagioclases, olivine and ilmenite content of lunar surface using clementine data by the method of spectra unmixed based Hapke model. The result reveals that the plagioclases content is of result equal to plagioclases content and glass content, no large area olivine exsits on the lunar, the result of ilmenite content is more than the fact, and the error of the pyroxenes is somehow a little big.(3)For the data CE-1 IIM, some batch programs were developed using IDL to repair the noise and stripe, to calibrate the reflection, to geocode and mosaic the files. By the angle parametric method, IIM data are used for mapping of FeO and Ti02.(4) The Oceanus Procellarum - Mare Imbrium region and some craters are coprehensively analyzed by multi-source information.
