 An example of such mountains is Alba Mons, which obtained its name 34 years after its crater Alba Patera.The geological term "highland patera" (a kind of low Martian volcanoes with radially channeled flanks), unlike the nomenclatural term "patera", refers to the whole volcano.The term "patera" (together with 12 other nomenclatural terms) was introduced into planetary nomenclature in 1973, on XV General Assembly of the International Astronomical Union, when 9 Martian paterae, imaged by Mariner 9 in 1972-1973, were named.
