The distribution fracture patterns of old Martian impact basins were studied. The basaltic plains on the Moon generally occur inside or around impact craters and basins and it is believed that fractures generated by large impacts provided long lasting pathways for magmas. The volcanic plains and volcanic edifices on Mars which show a complex distribution are the interiors of the most obvious old basins are largely buried by wind blown deposits. The Martian ridged plains that most resemble the lunar maria typically are offset from such impact basins. The origin of the mare like plains offset and the placement of the large volcanic mountains are discussed.
