  • Total extrusive and intrusive magma generated on Mars over the last ∼3.8 billion years is estimated at 654 x 106 cubic kilometers, or 0.17 cubic kilometers per year (km3/yr), substantially less than rates for Earth (26 to 34 km3/yr) and Venus (less than 20 km3/yr) but much more than for the Moon (0.025 km3/yr). When scaled to Earth's mass the martian rate is much smaller than that for Earth or Venus and slightly smaller than for the Moon.
