basalt is not a sedimentary rock. it is actually an igneous rock formed from cooled, melted rocks. in fact, basalt is classified as an extrusive see full answer below

almost all the rocks at the lunar surface are igneous—they formed from the cooling of lava. the two most common kinds are basalts and anorthosites.
