Abstract

Apoll 4 obtains 930 photographs from lunat orbit using he Tascibykdeund Hyaci cameras. I photegrapts reveal a numter new geologio fentures A the morpholegy, ,structre, and stratigraphy oflunar surfacc oits. The ruary relsthe verification of well as REviouslyvooognized dctails of the extensive role of voleanism inthe Pormation and modification ofthe lunathhightands,especially on the tanside Terra volanism appears to be manifest in the formation of() constructional units ofhilly and fuarrowed material ofs regtonal extent as in the Kant Plateau in the eentral ncarsido highlands Crater Pasteu near the eastern timb ofthe moon; (2)s somewhat viseous lava Nows and pools associated northwest of the with Dactip sostems and/or What appear be volanie craters O cralers, crater chains, and irregular depressions, particularly on the lumar farsicle, ( The trst photographs of a tow channel, a leveed sinuous rille that apparently originated by lava lowage on the surface aere obtained Apsllo 14. Another first is a high r resolution photograph of the interior of what appears to be the youngest hunar erater yet photographed in the 20-40 km size range. Also, photo- graphie sequenxes were madte at sero phase conditions andl at low sun clevation angles near the terminator, Ih latter condition are mest suitable tor studying small-scale topographic varations units M lunar surface units.
