Abstract：There are a variety of geological structures in the Oceanus Procellarum,including 43 craters,some famous lunar mares like Mare Imbrium and Mare Frigoris,and so on.Since the Oceanus Procellarum is the candidate landing area of lunar exploration for some countries,it is important to carry out the inversion of the minerals in the dark matter of craters of the area to facilitate research,exploration and utilization of lunar resources in the future.In addition,distribution of minerals on lunar surface is important since it concerns the origin and evolution of the moon.In this paper,the Oceanus Procellarum is taken as study area,the minerals in the dark matter of crater are inversed according to the spectra absorption characteristics in the visi-ble and near-infrared bands of different minerals like clinopyroxene,orthopyroxene,olivine and spinel from M3 (moon mineral-ogy mapper)data by spectral feature fitting.The mafic minerals extracted from the Oceanus Procellarum are relatively concen-trated.The content of pyroxene is more than spinel and olivine.And the geological significance and relationship among olivine, spinel and other extracted minerals in the vicinity are analyzed.A comparison of the mapping results of the optical model of Lu-cey on Clementine data reveals that the distribution of inversion results is consistent.In this paper,the extracted olivine distrib-uted concentratively,but there is no large scale distribution,it is associated with the study area of this article.
