勇气号火星车上的显微成像仪以100微米的分辨率分析了火星古瑟夫陨石坑的土壤和岩石的纹理。哥伦比亚纪念站附近的土壤中存在着弱结合的尘埃团块。一些刷状或磨损的岩石表面显示出火成岩结构，以及与次生矿化一致的蚀变皮、涂层和矿脉的证据。岩石结构与火山起源以及随后的撞击事件、风和可能还有水造成的蚀变和/或风化一致。
The Microscopic Imager on the Spirit rover analyzed the textures of the soil and rocks at Gusev crater on Mars at a resolution of 100 micrometers. Weakly bound agglomerates of dust are present in the soil near the Columbia Memorial Station. Some of the brushed or abraded rock surfaces show igneous textures and evidence for alteration rinds, coatings, and veins consistent with secondary mineralization. The rock textures are consistent with a volcanic origin and subsequent alteration and/or weathering by impact events, wind, and possibly water.
