The article considers geological and morphological features of a volcanic relief of a surface of a planet Mars. Effusive magmatism processes at early stages of planet crust forming come out in structure of solidified relief forms of Mars. The volcanic relief of a planet represents relic ancient line oriented forms and central lava flooding. Linear forms generate shield volcanoes, chains of volcanic mountains and radial-concentric faults. Hypsometric high-rise profiles of volcanoes and average slopes surface of the relief defined on the materials of Mars Orbiter Lazer Altimeter (MOLA) of the spacecraft Mars Global Surveyor (NASA). The relative age of volcanoes and volcanic plains is estimated on density of shock craters. The system of the nomenclature of names of volcanic and extended forms of relief Mars, according International Astronomical Union (IAU), is presented in paper. The results of studies give an opportunity to compare scientific and technical information about the planet and make considerably easier the usage of space survey material in studying the surface geomorphology of Mars in view of outlooks of the planet learning.
