Althowsh highland ftragments lie wnt 24 cote, tley shomuld provide an important source of information on the sequence ar eust-limb busins, k The numerous rays that erosS the Crist m bas in rees hlghland materials, Prochus Giordano Brano are esponsible for the most the basin, but discontinu ous rays and secondary craters of Langrenus and Tarur c tho basin. Individual bright components of Giordano ccntenl and eastern arts of rays weral small fresh craters (probable secondaries) that contribute to the overall ess the rlay. However, rays of Proclus have very gradstional boundaries with the surr S there no #pparent contrast between the rays and surrounding mare, with S local mit respect 100 m) crater frequencics Both deposition primary ejecta and reworking were most Wikely responsible for the formation of ray systems Mare Crisium. the faet that Luna 24 landed near the uprange end of a Giordano Bruno ray, incomplete SiLE ing he uppermost layer and formation of the ray by reworking of in situ regolith suggest that its aterials may ba scarce or.not present in the core Highland fragments present are most likely to be representative of several highland sources.
